Windows installer not working

Question

Hi,&nbsp;Since installing win 11, I have lost the ability to install .msi files.&nbsp; Everytime I try I get the following error:This is installing programs like Hugin or Blender. When I try to run as admin, I get the following:I have tried, starting/stopping in the services.msc,&nbsp; and unregistering/re-registering the windows installer. My windows is up to date.&nbsp;Can anyone suggest anything else to try?&nbsp;

KapilArya&nbsp;Thanks for the suggestion, turns out I don't have WOW64.Unsure if this is what is causing the issue, if it is I wouldn't know how to go about fixing it. Just tried google and couldn't really find anything

Uninstall windows and look up your product key. Then install it to a external drive then transfer it to the unit for reinstall.
