Cannot mount ISO file in Windows 11

Anonymous

My laptop came with Windows 11 Pro.

It will not mount an ISO file.

I've right-clicked, selected "mount", get the spinning wheel for a while, then get a message that there is an error mounting the file.

Tried right-clicking and selecting Open With... Windows Explorer. Same result.

Tried disabling 'Check Apps and Files' under "Windows Security/Reputation Based Protection". Doesn't work.

The file CAN be opened in VLC or other app (when it's a video file), so it is not the file (tried several).

The files also mount fine on my other PC which has Windows 10.

    Hello. I've tried all the steps listed in this thread, and none of it seems to work.

    I've run the Terminal and the RestoreHealth commands, restarted computer. I've followed the link to a solution, and got to the registry. The files that were listed weren't there, so there was nothing to delete.

    I've followed the advice of the post above me, and there is no "Windows/DeviceInstall" path to check for.

    I'm at a loss. Any other help?

    The simultaneous "inability to mount a file in Windows Explorer" and "inability to access cdrom resources" is highly likely tied to security software or setting which restricts cdrom access. This can be verified if you are able to load the image in powershell with: Mount-DiskImage -ImagePath "c:\sims.iso"

    Gives a result like this:

    Attached : True

    BlockSize : 0

    DevicePath : \.\CDROM0

    FileSize : 3550216192

    ImagePath : c:\sims.iso

    LogicalSectorSize : 2048

    Number : 0

    Size : 3550216192

    StorageType : 1

    PSComputerName :

    This means the iso was mounted. You will see an extra drive under you devices but will be unable to access this resource because some setting is blocking cdrom access.

    Also please check the following key with Registry Editor:

    Registry Hive HKEY_LOCAL_MACHINE
    Registry Path Software\Policies\Microsoft\Windows\DeviceInstall\Restrictions
    Value Name DenyDeviceIDs
    Value Type REG_DWORD
    Enabled Value 1
    Disabled Value 0

    Make sure it is disable.

    If you were unable to mount the file either the iso is corrupt or you have corrupted your Windows installation.

    Virtual Drive makers of any and all kinds will also run into the same problem; ability to mount ok, ability to read mounted contents denied. The more intelligent ones will report a mount failure error simply because the contents cannot be read thus cannot be verified.

    Just saw this error when trying again to mount an ISO:

    However, I cannot seem to be able to uninstall, delete, or update the driver.

    This is the received error message I receive after several minutes of the spinning circle.
