How to Solve Errors

There are several troubleshooting steps you can take to resolve error code 0x36b1. Try them one by one until the issue is fixed.

Run System File Checker

System File Checker (SFC) scans your system for corrupted files and attempts to repair them. To run SFC:

  • Open Command Prompt as administrator (search for "cmd", right-click, and select "Run as administrator").

  • Type sfc /scannow and press Enter.

Let the scan complete; it may take some time. Restart your computer after the scan finishes.

Check Disk Space

Ensure you have sufficient free space on your hard drive to accommodate the installation. To check disk space:

  • Open File Explorer (press Windows key + E).

  • Navigate to "This PC" in the left pane.

  • Look at the available space for your main drive (typically C:).

If space is limited, delete unnecessary files or programs to free up space.

Temporarily Disable Antivirus

Temporarily disable your antivirus software during installation and re-enable it afterward. Some antivirus programs may interfere with the installation process.

Run as Administrator

Run the installation program as an administrator. Right-click on the installer file and select "Run as administrator" from the context menu.

Check User Permissions

Ensure you have sufficient permissions to write to the installation directory. You can check and modify user permissions through the File Explorer properties window for the installation folder.

Reset Windows Update Components

Sometimes resetting Windows update components can resolve installation issues. To do this:

  • Open Command Prompt as administrator.

  • Execute the following commands, pressing Enter after each one:

    • net stop wuauserv
    • net stop cryptSvc
    • net stop bits
    • net stop msiserver
    • ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    • ren C:\Windows\System32\catroot2 Catroot2.old

  • Restart the services by running the following commands:

    • net start wuauserv
    • net start cryptSvc
    • net start bits
    • net start msiserver

Clean Boot Windows

Performing a clean boot helps isolate software conflicts that might be causing the error. To do this:

  • Search for "System Configuration" and open it.

  • Go to the "Services" tab and check "Hide all Microsoft services".

  • Click "Disable All".

  • Go to the "Startup" tab and click "Open Task Manager".

  • Disable all startup items in the Task Manager.

  • Close Task Manager and click "OK" in System Configuration.

  • Restart your computer.

  • After restarting, try installing the program again. If the installation succeeds, a third-party program was likely causing the conflict. Re-enable services and startup items one by one to identify the culprit.
