Product version: 10.9

Last modified: 23 March 2023


When attempting to create bootable media on a physical machine running Windows OS, the job fails.

Alternatively, attempting to manually mount an ISO file in Windows returns the following error:

Couldn't Mount File

Sorry, there was a problem mounting the file.


To resolve this issue, try the following:

  1. Open regedit in your Windows machine by typing regedit in the Search window, right-clicking it, and selecting Run as Administrator.

  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}.

  3. On the right side of the window, click UpperFilters. Then, right-click it and select Delete. Do not delete UpperFilters.bak.

  4. Repeat step 3 for LowerFilters. Do not delete LowerFilters.bak.

  5. Save your changes and reboot the machine.

  6. Try creating bootable media or mounting the ISO file again.
