9 Remedies to Clear Windows Setup Stuck on Validation Error

Do you see a “verifying installation” prompt whenever you launch Steam? This prompt appears when Steam is cross-checking the game files in its database with those on your computer. Normally, this process should take only a few seconds.

However, if Steam takes an unusually long time to verify the files, it’s a sign that something is amiss. This can happen due to corrupt Steam files, weak internet connection, or lack of administrative permissions. As such, if Steam gets stuck in the “verifying installation” process, use the following solutions to get it fixed

1. Restart the Steam Client

Whenever Steam gets stuck on the “verifying installation” process, your first port of call should be to restart the Steam client. Restarting the client will clear any temporary files, cached data, or other resources that might be triggering the problem.

So, restart and check if it makes any difference. If not, then try the next solution.

2. Check Your Internet Connection

Steam requires a strong internet connection to verify the game files. However, if your connection is weak or unstable, Steam might get stuck in the verification process.

You can use an internet-speed testing website to check your internet speed and stability. If the result shows your connection is slow and unstable, try the following solutions:

• Restart the router.
• Update your network driver .
• Reset the network settings on Windows .

However, if none of the above solutions work, you’ll have to contact your ISP.

3. Launch Steam With Administrative Rights

Another quick way to fix the problem is to launch the Steam client with administrative privileges. Granting elevated rights will ensure that Steam has the required permissions to access and verify the game files.

To launch Steam as an administrator, follow the below instructions:

1. Right-click on the Steam client and chooseProperties from the context menu.
2. Switch to theCompatibility tab.
3. Check theRun this program as an administrator box.
