Installed on a Win10 Pro x64 VMWare VM.
Took a snapshot of the VM first though.
Applied a package and all looked well.
Applied Windows default package.
... the icon for Icon Packager went to a generic blank icon
... the icon for Internet Explorer went to a generic blank icon
Internet Explorer Icon still broke. Had to right click on it and change icon. That fixed it.
Reverted VM back to snapshot, re-installed IP and could not reproduce the issue.
Took another snapshot of VM.
All icons still look fine.
Reverted VM back to snapshot #2 ( the one that has IP installed ).
All works well.
Note: the only other Stardock app installed on the VM is Fences.
