I have an issue with our domain and policies where a user needs administrative rights to install a program and someone provides the credentials for the 'run as admin' or 'run as other user' it will always show an error:

Cannot find specified file on the drive.

So we cannot install programs for our employees. How I fix it is I add the user to administrators, force a policy update, have them reboot, run as administrator and install it that way. Then remove them after and update the policy.

Another way was to right click the install file (.exe/.msi) and add the user and administrator as an owner with full control. Only works when we have the installation file.

I have no idea how to fix this and I can't find a relevant thread or QA about this problem. I can only find users having issues on their home computers not on a domain.

Any help and threads to read would be great!
