Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →regcleanpro.dll is a third-party application file, not a Windows component, and it should not normally be copied into System32 or SysWOW64. The safest fix is to identify the program that requested it, then repair, reinstall, or remove that parent application.
What this file actually does
The filename is associated with software rather than with Windows itself. Public records describe it as part of DLL download sites Fixer, while separate software inventories associate RegCleanPro.dll with RegClean Pro from Systweak.
Those records are inconsistent, so the filename alone cannot prove which program installed your copy. Do not assume that every file named regcleanpro.dll is the same binary.
Catalogue records describe versions including 3.1.81.2796, 3.0.81.2643, 2.9.72.2517, 2.7.72.2024, and 2.0.72.2024. The listed files are 32-bit Win32 DLLs, with reported sizes ranging from approximately 1.57 MB to 2.86 MB. This is catalogue metadata, not proof that any downloaded copy is safe or suitable for your computer.

regcleanpro.dll is not known to be:
- A Windows system file
- A Microsoft Visual C++ runtime
- A DirectX component
- A .NET file
- A driver
- Game middleware
The error may appear as “regcleanpro.dll is missing,” “cannot find regcleanpro.dll,” “error loading regcleanpro.dll,” or “the specified module could not be found.” The last message is important: it can mean that regcleanpro.dll exists but one of its dependencies is missing.
Causes and fixes at a glance
| What you notice | Most likely cause | Best next step |
|---|---|---|
| The error appears when Windows starts | A removed program left a startup reference | Identify and remove the parent program or its startup entry |
| The error appears when launching RegClean Pro or a similar utility | The application is damaged or incomplete | Repair or reinstall the application |
| The file disappeared after a security alert | Antivirus quarantine | Inspect Protection history before restoring anything |
| The file exists, but Windows says a module cannot be found | A dependency is missing | Reinstall the parent application and its required runtime |
| The program was unexpectedly installed | Bundled or potentially unwanted software | Scan the computer and uninstall the parent application |
| Several Windows programs also fail | Broader system corruption | Run DISM, then SFC |
| Reinstalling does not help | Wrong owner, wrong architecture, leftover startup task, or dependency failure | Record the path, signature, application name, and exact error |
Identify the program that owns the file
Before downloading anything, determine which executable is requesting the DLL.
Check the error and file location
Read the complete error message. It may identify the application that attempted to load regcleanpro.dll.
If the file still exists:
- Press Windows + S.
- Search for
regcleanpro.dll. - Right-click the result and select Open file location.
- Note the full folder path.
- Right-click the DLL and select Properties.
- Open the Details tab.
- Check the Digital Signatures tab, if present.
A DLL inside a clearly named application folder is more useful evidence than the filename itself. A copy in an unexpected temporary folder, a user profile subfolder, or a random system directory deserves additional scrutiny.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesThe Properties dialog may show a product name, company name, file version, or signer. It may also show little useful information. An absent signature does not automatically prove malware, but it means you should rely more heavily on the file path, the installed program, antivirus results, and the installer’s provenance.
Also check the application list:
- Open Settings.
- Select Apps.
- Select Installed apps.
- Search for RegClean Pro, DLL download sites Fixer, or another program named in the error.
- Select the program’s three-dot menu.
If the program is not listed, check Control Panel > Programs > Programs and Features as well. A leftover startup entry may still be calling a program that has already been removed.
Fix 1: Repair or reinstall the parent application
This is the most likely solution when the error began after an update, failed cleanup, interrupted installation, or partial uninstall.
First decide whether you still want the application. If you do not recognize it, or it arrived bundled with another download, removal is safer than replacing its DLL.

Use Windows repair options first
- Open Settings > Apps > Installed apps.
- Find the suspected parent application.
- Select the three-dot menu.
- Choose Advanced options, if available.
- Select Repair.
- Restart Windows and test the application.
If Repair is unavailable or does not work:
- Return to the application’s menu.
- Select Uninstall.
- Complete the uninstall wizard.
- Restart the computer.
- Download the application again only from its publisher’s official source.
- Install it using an administrator account.
- Launch the program and check whether the error has disappeared.
For RegClean Pro, use the publisher’s official Systweak download and support pages rather than a standalone DLL source. If the program is unwanted, leave it uninstalled and remove its remaining startup reference instead.
A successful repair means the parent application opens without the DLL dialog and its normal features work. If the same error returns immediately, verify that you repaired the correct application. The conflicting public ownership records make this check essential.
Fix 2: Check antivirus quarantine before restoring anything
Windows Defender or another antivirus product may have quarantined the DLL after a detection, software update, or change in security definitions.
To inspect Microsoft Defender:
- Open Start.
- Search for Windows Security and open it.
- Select Virus & threat protection.
- Select Protection history.
- Review entries related to
regcleanpro.dllor its parent application. - Expand the detection and record the file path and detection name.
Microsoft explains the available quarantine actions in its Protection History guidance.
Free tools Windows power users keep installed
One-click scans. No signup required.
Do not restore the file merely because an application now reports it as missing. A missing file after quarantine may indicate that the application is unwanted or that the file was detected as unsafe. Prefer uninstalling the parent application or reinstalling it from its official publisher.
Restore a quarantined file only when you have independently established its provenance and are confident the detection is a false positive. Never disable antivirus protection just to force an unverified DLL to load.
After dealing with the detection, run a full scan:
- Open Windows Security.
- Select Virus & threat protection.
- Select Scan options.
- Choose Full scan.
- Select Scan now.
If the error returns after reboot or the program appears to recreate itself, use Microsoft Defender Offline from the same Scan options screen. Microsoft’s Defender scan guidance explains the available scan types.
Fix 3: Remove a leftover startup reference
If the parent program has been uninstalled but Windows still displays the error at sign-in, an autostart entry may be trying to launch a removed executable.

Check Startup apps:
- Press Ctrl + Shift + Esc to open Task Manager.
- Select Startup apps.
- Look for entries clearly associated with RegClean Pro, DLL download sites Fixer, or the application shown in the error.
- Right-click the identified entry.
- Select Disable.
- Restart Windows.
You can also inspect scheduled tasks:
- Press Windows + S.
- Search for Task Scheduler and open it.
- Select Task Scheduler Library.
- Review tasks with an unmistakable name matching the removed application.
- Open a task’s Actions tab to see what it launches.
- Disable or delete only entries you can confidently identify as belonging to the removed program.
Do not delete arbitrary registry values or tasks simply because their names look unfamiliar. If the error stops after disabling the confirmed entry, the DLL was not the real repair target; the orphaned startup reference was.
Fix 4: Resolve a missing dependency
“The specified module could not be found” does not always mean that regcleanpro.dll itself is absent. Windows may be unable to load a library required by that DLL.
Start by reinstalling the parent application. Its installer is the safest way to restore the complete group of private libraries and dependencies.
The catalogue records for this file identify it as 32-bit. A 32-bit application runs on 64-bit Windows, but it normally needs 32-bit dependencies. If the application documentation specifically requires Microsoft Visual C++, install the required package from Microsoft’s Visual C++ Redistributable downloads. For a 32-bit application, the relevant package is generally the x86 redistributable. Do not claim that this package contains regcleanpro.dll; it does not.

If reinstalling the parent application and its documented runtime does not help, record the exact error, application path, DLL path, and any event-log entry. A dependency diagnostic from the application vendor may then be needed.
Fix 5: Repair Windows components only when Windows itself is damaged
DISM and SFC are not primary repairs for a private third-party DLL. SFC repairs protected Windows components, not application files such as regcleanpro.dll.
Use them when other Windows features are also malfunctioning, system files are corrupted, or the problem followed a broader Windows failure.

- Open Start.
- Type Command Prompt.
- Right-click it and select Run as administrator.
- Select Yes at the User Account Control prompt.
- Run:
DISM.exe /Online /Cleanup-Image /RestoreHealth
- Wait for the operation to complete.
- Then run:
sfc /scannow
- Restart Windows.
Microsoft recommends running DISM before SFC in its System File Checker instructions.
If both commands complete successfully but the application still reports the DLL error, return to repairing or reinstalling the parent program.
Repeating SFC and DISM without knowing what changed can make troubleshooting feel like guesswork. Outbyte PC Repair can scan for broader system problems and show what it identifies; repairs are performed by the full version, and it is not required for this DLL-specific fix.
Fix 6: Check drivers only when the application points to a driver problem
A driver is not the normal explanation for regcleanpro.dll, and Device Manager will not replace this application DLL. Use it only if the error began alongside a graphics, storage, security, or other device failure and the application documentation identifies that device as relevant.
Recommended Free Tools
- Right-click Start.
- Select Device Manager.
- Expand the device category named in the application’s error or support instructions.
- Right-click the device.
- Select Properties.
- Open the Driver tab.
- Check the driver provider and date.
- Use Update Driver only with a driver obtained through Windows Update or the hardware manufacturer.
- Restart Windows and retest the application.
Guessing among dozens of drivers is slower and can introduce a mismatched package. Outbyte Driver Updater can scan and identify outdated drivers; the full version performs driver installation, but updating drivers is not a substitute for reinstalling the application that owns regcleanpro.dll.
Do not copy the DLL or register it automatically
Avoid downloading regcleanpro.dll from random DLL download websites. A standalone copy may contain malware, be the wrong version, use the wrong architecture, or fail because the actual problem is a missing dependency or a damaged parent application.
Do not copy it into C:WindowsSystem32 or C:WindowsSysWOW64. Those folders are not general-purpose repair locations, and placing an unverified DLL there can create a second problem.
Also do not run regsvr32 automatically. That command is intended for DLLs that expose a COM registration entry point, commonly DllRegisterServer. There is no reliable evidence that regcleanpro.dll should be registered. If the publisher specifically instructs you to register this file and confirms that it supports that entry point, follow the publisher’s exact architecture-specific command. Otherwise, reinstall the parent application.
Use System Restore for a recent change
If the error began immediately after installing or removing the related software, System Restore may reverse that change without affecting personal files.
- Press Windows + R.
- Type
rstrui.exe. - Press Enter.
- Select Next.
- Choose a restore point from before the problem began.
- Select Next > Finish.
- Allow Windows to restart.
This works only if a suitable restore point exists. Microsoft describes the process in its System Restore guidance.

FAQ
Is regcleanpro.dll a Windows file?
No. It is associated with third-party software, including records for DLL download sites Fixer and RegClean Pro. It should not normally be installed in a Windows system directory.
Which program installed it?
The filename alone cannot establish that. Check the application named in the error, the DLL’s folder, Properties details, digital signature, and installed-program list.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →Is the file malware?
Not automatically. RegClean Pro has appeared in reports involving potentially unwanted software, but that does not prove that every copy of regcleanpro.dll is malicious. Check its provenance and antivirus detection before deciding whether to restore or remove it.
Should I install Visual C++?
Only if the parent application specifically requires it. The Visual C++ Redistributable does not contain regcleanpro.dll.
Can I fix the error with regsvr32?
Usually not. There is no evidence that this private application DLL requires COM registration. Reinstall the owning application instead.
What if the program has already been removed?
Look for a clearly identified leftover entry in Task Manager > Startup apps or Task Scheduler. Removing the orphaned reference may be the correct fix, rather than restoring the DLL.
What information should I provide to support?
Record the full error text, application name, DLL path, file Properties details, digital signature status, antivirus detection, Windows architecture, and whether the problem began after an install, update, uninstall, or quarantine event.
