  1. Option does not work 100% I can mount the .ISO after following “Mikes” correct steps.

    I can then install the software, but when I go to run it, even though the .iso is still mounted and in explorer/ This PC, the program says it cannot find the disc.

    So problem not fixed if MS can’t mount .ISO so the mounted .ISO can be found by the software that is installed from the mounted, and left mounted, .ISO.

    Need fix for that problem.

    PS. Damon tools and WinCDEmu both have same issue…

    Running Win 10 1903 Ent, 32 bit in VM to run old educational learning software.

  2. Why is every single solution to this in Google supplying this garbage incorrect info? Just wasted half an hour trying this crap before I found Mikes comments with the actual answer…

  3. This article is worthless doesn’t work at all.
    If you want to mount an ISO simply do this.
    right-click the iso, and select properties in the menu.

    Under Opens with, select Change to change the file association

    select Windows Explorer

    After that you will have the Mount Icon back
