Some software applications do require the user to have administrative rights to run them correctly. And I have had this same issue with other software application installations and implementations. This is the workaround that works for us, add the user to the Domain Admins group and give the user admin rightrs. This is all temporary just while you are making the installation.
1. Add Domain Admins group rights to the user from the domain controller. Ensure the domain is synchronized before logging in as the user.
2. Add the user to the Administrators group on the local machine.
3. Log in as the user and install the application.
4. Launch the application and test it while logged in as the user with the temporary admin rights.
5. Log off as the user, log back in as administrator and remove the user from the local administrator group.
6. You may have to add the Everyone group "Full Control" permissions on the Program Groups application folder located at C:\Program Files\%Application Name%
7. Remove the Domain Admins group from the user profile on the domain controller.
8. Log back in as the user without admin rights this time and test the application again. This usually resolves any of the issues we have had with permissionsfor users.
9. If you have the option, one more thing that may resolve the issue relating to fax/print/copier permissions is to add the user to the Power Users group on the local machine.
Hope this helps!
