  1. Unable to Mount ISO file in Windows Explorer


    Please note : I am able to open the ISO with other programs (Winrar, 7zip, etc)


    I am desperate, looking for help. I have scoured the web far and wide and cannot find a solution to my issue and I refuse to believe that reformatting my PC is the only way to fix this issue.


    My issue is, I want to be able to mount iso files (and have been able to do so in the past) with windows explorer. I get the "mount" option when i right click, but when I select it, or select to open the file through windows explorer, I get an error that reads " Sorry, there was a problem mounting the file"

    I have Windows 10 Home x64

    I have tried;

    copying the file to another drive(its currently in "D:/backup.iso" (My C: drive is my windows install drive). I get the same error as above no matter where i copy it (ctrl+c while the iso is selected, ctrl+v somewhere else)


    checking file permissions and read status

    Changing (and checking) the sparse flag in an elevated command prompt
    "fsutil sparse setflag {PathToISO} 0"




    Checking to see if there was already a mounted drive/file(there isn't)


    changing the default file extension app, but the .iso file type isn't even listed.

    This led me to believe there was a incorrect registry entry(s). I thought the only entry I needed to worry about was in "Computer\HKEY_CLASSES_ROOT\.iso", but it seems like the entries there are correct, and there are hundreds more entries that came up in search related to the string ".iso". Here are a few entries i thought relevant.

    I apologize for the long post. There seems to be no end to this. I know I can just open the file with Winrar, but I want to be able to open the file in explorer like i have been able to do in the past, (albeit a while ago). I am truly at my wits end here.

    I would greatly appreciate any help.

    :)

    Error mounting .ISO files in Windows 10

    Hi,

    There are several reasons why you are having issues mounting ISO files on your Windows 10 Home computer. To assist you better, kindly answer the questions below:

    • What other troubleshooting steps have you done so far?
    • Have you tried mounting the ISO files on another computer?
    • Have you tried copying the ISO file to your desktop and mount it from there?
    • Do you have a CD/DVD drive installed on your computer?

    Regards.

  3. Windows 10 Mount Iso

    Hi, I´m Douglas M.

    I would like to help you, When you right click an ISO file and Mount does not show at top of list the the file association is wrong.

    Click on Open With and you need to make Windows Explorer the default.

    After that the Mount choice will be there.

    kinds Regards
