If Windows says it is missing or cannot load, repair Windows and identify the triggering application instead of downloading a replacement DLL.
What this file actually does
The full component name is Remote Desktop PnP Redirected Device Co-Installer. It belongs to the Windows Remote Desktop and Plug and Play redirection family. In supported configurations, Remote Desktop can make selected local devices available to a remote Windows session, subject to Windows settings and policy.

Those inventories are not authoritative Microsoft package manifests, and they do not prove that the same file is packaged identically in every Windows 10 or Windows 11 build. Do not choose a replacement based only on a filename, file size, or an old version table.
A program may be the first place you see the error because it starts a component that Windows can no longer load. That does not necessarily mean the program owns the DLL or that reinstalling Visual C++ will help.
Causes by symptom
| What you see | Most likely explanation | Best first action |
|---|---|---|
| The error started after Windows Update or a failed upgrade | Windows component or servicing damage | Install pending updates, then run DISM and SFC |
| Antivirus lists the file in quarantine | A legitimate file was removed, or a tampered copy was detected | Check its path and digital signature before restoring |
| Only one old program reports the error | The program may have a damaged installer or an incorrect dependency reference | Repair or reinstall that program from its official source |
| Several Windows features or DLLs fail | Broader component-store or system-file corruption | Run DISM followed by SFC |
| “The specified module could not be found” appears while the file exists | A dependency may be missing, or the file may be corrupt or mismatched | Check the path and signature, then repair Windows |
| The error began after a cleanup utility ran | The utility may have removed a protected or referenced file | Undo the cleanup if possible and use Windows repair tools |
| The file repeatedly returns to antivirus quarantine | Malware, tampering, or an invalid replacement may be involved | Do not keep restoring it; run a full security scan |
Fix 1: Install Windows updates and restart
Start with Windows servicing because the correct copy must match your Windows build and architecture.
- Open Start > Settings.
- Select Windows Update.
- On Windows 10, open Update & Security > Windows Update.
- Select Check for updates.
- Install all available quality, security, and servicing updates.
- Restart the computer, even if Windows does not immediately require it.
- Try the program or Remote Desktop action that produced the error.
If Windows Update itself fails, restart once more and check again. A damaged update cache or component store can prevent Windows from restoring protected files, so continue with DISM and SFC if the message remains.
Fix 2: Repair the Windows component store with DISM
DISM repairs the Windows component store, which Windows uses to restore protected system files.
- Open Start.
- Type
Command Prompt. - Right-click Command Prompt and select Run as administrator.
- Approve the User Account Control prompt.
- Run this command:
DISM.exe /Online /Cleanup-Image /RestoreHealth
- Wait for the operation to finish. Do not close the window if progress appears to pause.
- Restart Windows after DISM completes.
A successful result normally reports that the restore operation completed successfully. If DISM says it cannot find source files, do not download tspnprdrcoinstaller.dll separately. Use a matching Windows installation source or continue to the recovery options below.
Microsoft’s DISM repair guidance explains how to provide a repair source. A source must closely match the installed Windows edition and version. The command has this form:
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess
Replace the example path only when you have a legitimate, matching repair source.
The manual route requires identifying the right Windows build, finding compatible installation media, and interpreting DISM output. Outbyte PC Repair can show a scan of system problems and performs repairs with its full version, but it is optional and does not replace a Windows repair installation when the component store is seriously damaged.
For Windows 7, do not blindly use the modern /Cleanup-Image sequence. Microsoft documents different repair considerations for that release. Use Windows Update, SFC, the appropriate servicing package, or System Restore instead.
Fix 3: Run System File Checker
Run SFC after DISM, not before. DISM repairs the source that SFC depends on.
Free tools Windows power users keep installed
One-click scans. No signup required.
- Open Command Prompt as administrator again.
- Enter:
sfc /scannow
- Wait until verification reaches 100 percent.
- Restart Windows.
- Test the affected program again.
Microsoft’s System File Checker documentation describes the possible results:
- Windows Resource Protection did not find any integrity violations: SFC found no damaged protected files. The named DLL may not be the real cause, or a dependency may be missing.
- Windows Resource Protection found corrupt files and successfully repaired them: restart and test again.
- Windows Resource Protection found corrupt files but was unable to fix some of them: run DISM again, check Windows Update, and consider System Restore or an in-place repair.
- Windows Resource Protection could not perform the requested operation: restart into Safe Mode and repeat the scan, or use Windows Recovery Environment.
If SFC cannot repair the file, repair details may be recorded in:
%windir%LogsCBSCBS.log
The log is technical, but it can confirm whether Windows identified the file as damaged or whether another component caused the failure.
Fix 4: Check antivirus quarantine and verify the file
A security product may quarantine a legitimate Windows file, but a file with a Microsoft-like name is not automatically safe.

Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstall- Open Windows Security from the Start menu.
- Select Virus & threat protection.
- Open Protection history.
- Look for an entry involving
tspnprdrcoinstaller.dll. - Record the detected path and reason.
- If the file is quarantined, do not restore it immediately.
- Check whether its original location was an expected Windows directory, such as
C:WindowsSystem32. - In File Explorer, right-click any existing copy, select Properties, and inspect the Digital Signatures tab.
- Restore it only when the path and Microsoft signature are consistent with a legitimate Windows component.
If antivirus repeatedly quarantines the file, stop restoring it. Update the security definitions and run a Full scan in Windows Security. A repeated detection can indicate malware, a tampered file, or an untrusted replacement.
Even when quarantine caused the immediate error, DISM and SFC are safer ways to restore the correct build than copying a file from another computer.
Fix 5: Repair the program that triggers the message
If the error appears only when launching one older application, that application may be using an incorrect or damaged reference. The program is not necessarily the owner of this Windows DLL.
- Note the exact application name and the complete error text.
- Open Settings > Apps > Installed apps.
- Select the affected program.
- Choose Advanced options if available.
- Select Repair.
- If Repair is unavailable or ineffective, select Uninstall.
- Restart Windows.
- Download the latest installer from the application developer’s official website.
- Install the program again and test it.
For a game, use its launcher’s Verify, Repair, or equivalent file-checking command before reinstalling the entire game. Do not allow an installer to replace protected Windows files with a copy from an unknown source.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If the program is old, it may reference a component that is not present in your current Windows build. Contact the developer or install a current version rather than forcing an older DLL into System32.
Fix 6: Check Remote Desktop and device redirection settings
This file is associated with Remote Desktop Plug and Play redirection. If the error appears only during an RDP session or when connecting a redirected device, check the session configuration.
- Disconnect the Remote Desktop session.
- Open Remote Desktop Connection by searching for
Remote Desktop Connection. - Select Show Options.
- Open the Local Resources tab.
- Select More under Local devices and resources.
- Review the devices being redirected.
- Temporarily clear a device category that is not required.
- Reconnect and test.
On managed computers, group policy may control device redirection. A policy change can affect whether local devices are exposed to the remote session, but it will not repair a corrupted Windows component. If the failure continues, return to DISM and SFC rather than repeatedly changing redirection settings.
Fix 7: Update or reinstall a related driver
If the error began while connecting a printer, camera, storage device, or another Plug and Play peripheral, update that device through Windows or its manufacturer.
- Right-click Start and select Device Manager.
- Expand the category related to the device.
- Right-click the device and select Update driver.
- Choose Search automatically for drivers.
- Restart Windows if a driver is installed.
- If the problem began after a driver update, open Properties > Driver and select Roll Back Driver when available.
- If the device remains broken, select Uninstall device, restart, and let Windows detect it again.
Avoid forcing a driver intended for a different Windows architecture. A 32-bit and 64-bit driver or DLL are not interchangeable.
Manually checking hardware vendors, driver dates, and compatible architectures can take time. Outbyte Driver Updater can scan for outdated drivers and installs updates with its full version, but it is optional, and the device manufacturer remains the authoritative source for specialized drivers.
Fix 8: Use System Restore
Use System Restore when the problem began immediately after an update, cleanup operation, driver change, or software installation and a suitable restore point exists.
- Press Windows + R.
- Type:
rstrui.exe
- Press Enter.
- Select Next.
- Choose a restore point dated before the error began.
- Select Scan for affected programs if available.
- Confirm the restore point and select Finish.
- Let Windows restart and complete the process.
System Restore normally rolls back system files, drivers, installed programs, and settings without removing personal documents. It is not a substitute for a backup.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Fix 9: Perform an in-place Windows repair
If DISM and SFC repeatedly fail, several protected files are damaged, or Windows Update cannot repair the component store, use official Windows installation media for an in-place repair.
Use installation media that matches the installed Windows edition and architecture. Start setup.exe from within Windows and choose the option to keep personal files and applications when it is offered. Read every screen carefully before confirming.
A repair installation is preferable to copying a DLL because it restores Windows components as a matched set. Back up important files first, and do not begin a repair if you are unsure which edition or installation option applies.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesDo not download or register the DLL manually
Do not download tspnprdrcoinstaller.dll from a random DLL library. A loose download can have the wrong Windows version, wrong architecture, invalid signature, damaged dependencies, or malicious code. It may also hide the actual component-store problem.
Do not copy a Windows 7 or Windows 8-era file into a Windows 10 or Windows 11 installation simply because the filename matches. Do not use System32 as a universal destination.
regsvr32 is also not a general DLL repair command. It applies only to libraries that provide the appropriate registration entry point. Microsoft explains DLL self-registration and Regsvr32 troubleshooting. Unless a verified installer or Microsoft documentation specifically requires registration, do not run:
Best Value
regsvr32 tspnprdrcoinstaller.dll
A registration error does not prove that the file is missing, and successful registration would not repair a damaged Windows component store.
What to report when asking for help
Record these details before escalating:
- Windows edition, version, and build
- Whether the system is 32-bit or 64-bit
- The complete error message
- The program or device that triggers it
- Whether the error occurs outside that program
- The path of any existing copy of the DLL
- Whether antivirus quarantined it
- The result of DISM and
sfc /scannow - Whether the problem began after an update, driver installation, cleanup tool, or software installation
The most useful distinction is whether the file is genuinely absent, present but unsigned or corrupt, or present while one of its dependencies is missing. That distinction determines whether Windows repair, application repair, driver work, or malware investigation is the correct next step.
FAQ
Is tspnprdrcoinstaller.dll safe?
It is a genuine Microsoft Windows component name associated with Remote Desktop Plug and Play redirection. A particular copy is safe only when its location, signature, and integrity are consistent with Windows. The name alone is not proof.
Should I reinstall Visual C++ Redistributable?
Usually not. This file is associated with Windows Remote Desktop device redirection, not Visual C++ Redistributable. Repair Windows first and identify the application that triggers the message.
Does missing this file break normal Windows use?
Not necessarily. The impact depends on what is trying to load it. You may notice the problem only during a Remote Desktop operation, device-redirection task, or an application with a faulty dependency reference.
Is it a Windows 10 or Windows 11 file?
Public inventories clearly associate the file with older Windows releases. Current Windows 10 and Windows 11 package coverage should be verified against the installed build rather than assumed from an old file listing.
Where should the file be restored?
Let Windows servicing restore it. Do not manually choose a destination or copy a downloaded DLL into System32.
What if the message says “The specified module could not be found”?
That message can mean a dependency is missing even when tspnprdrcoinstaller.dll exists. Check its path and signature, then run DISM and SFC before replacing anything.
