How to Fix “An Error Occurred While Updating” in Steam

Steam’s generic update error does not name its cause. Check the parenthetical reason, try Steam’s built-in fixes, and investigate system issues carefully if it persists.

Steam’s “An error occurred while updating [game title]” or “An error occurred while installing [game title]” message means the install or update failed; it does not identify the cause by itself. First check for a specific reason in parentheses at the end of the message, then work through Steam’s built-in troubleshooting steps.

Read the full error message first

Write down the game name and any parenthetical reason at the end of the message. Steam Support’s “Update & Installation Issues” article says: “The specific reason for the error will be shown in the parenthesis at the end of the error message.” The generic wording alone cannot tell you whether the problem is with a content server, local permissions, storage, or something else.

Try Steam’s basic troubleshooting steps

Try these in order, checking whether the affected game can update or install after each step.

  1. Restart Steam and your computer. Fully exit Steam, reopen it, and retry. If the error remains, restart the computer and try again.
  2. Clear the download cache. In Steam, open Steam > Settings > Downloads and select Clear Download Cache. Steam may ask you to sign in again afterward.
  3. Repair the game’s library folder. Open Steam > Settings > Storage, select the relevant library, open its options menu, and choose the repair option. Labels can vary slightly by Steam version.
  4. Verify the game’s installed files. Go to Library, right-click the game, and select Properties > Installed Files > Verify Integrity of Game Files. Let Steam finish before retrying the update.

Try a different download region

A regional Steam content server may be slow, overloaded, or experiencing hardware trouble. To test that possibility, open Steam > Settings > Downloads, select a different Download Region, then retry the download. This is a diagnostic change, not proof that the original region was at fault.

Test another Steam library location

If you have another drive or library folder available, try installing or moving the game there. In Steam > Settings > Storage, add or select another library location, then use the game’s storage or move option to test it. If the game works from another location, that is useful evidence to investigate the original library or drive; it does not by itself establish a hardware failure. This step is optional and does not mean you need to buy another drive.

When the error persists

If Steam’s basic steps do not help, investigate system-level possibilities rather than assuming a single cause. Steam lists network equipment, operating-system or driver issues, firewall or antivirus interference, background programs that monitor or modify disk or network activity, overclocking, drive health, and RAM among the areas to consider.

  • Note whether other downloads or network services are affected, and check for interruptions from network equipment.
  • Review recent operating-system, driver, security-software, or background-program changes that coincide with the failure.
  • If you suspect security software, do not leave protections disabled. Steam frames temporary disabling as a test to handle with specialist assistance.
  • Consider storage or memory diagnostics only when other evidence points in that direction; the Steam message alone does not diagnose either component.

Steam recommends contacting a local IT specialist for advanced troubleshooting. Its guidance also lists reinstalling Steam to the same location, but warns that uninstalling Steam deletes all game content. Do not uninstall until you understand that consequence and have protected any content you need to keep.
