Windows 10: Explorer fails to open && mount .ISO files - where 7zip has no problems

Hi community!I have some trouble to open certain .iso files on my Windows 10 Pro Version 20H2, Build 19042.985, Experience Pack 120.2212.2020.0 --> latest available level for my system without outstanding updates:I created MacOS .iso files on my Mac and want to use them for a VMWare installation on my Windows 10 system. I copied them via local LAN. Booting the VM fails with "Guest: Status upon boot failure: No Media" which made me suspect, that there is a problem with the image.As I try to open it with the explorer, I receive the error that the file is damaged: I also tried

Error when mounting ISO files

Hi,



Thank you for writing to Microsoft Community Forums.



I understand when you are trying to delete/rename/move the ISO files after mounting it you get an error message. It could be possible that the ISO file is mounted and that is the reason you are unable to modify it.



I suggest you to eject the ISO file and then try to modify it. Please follow the steps mentioned below:

1. Press Windows key + E, to open
   File Explorer.
   
2. Click on This PC on the left pane, you will find the mounted ISO file.
   
3. Right click on the ISO file and click on Eject. Try modifying the ISO file now.
   

Please reply with the status of the issue, we will be glad to help you further.

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 a elevated command prompt
"fsutil sparse setflag {PathToISO} 0"



Running "sfc /scannow" in a elevated command prompt (no errors returned)


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.
