Scripting

While this may seem simple, I haven't been getting it to work. I need to uninstall a program. But first, I need to find the new version of the program to verify that it is on the computer targeted by the script. Here is the rub:

The new version, RingCentral Meetings 5.4, is installed on the users' profile. It is not installed in the Program Files or any other standard location for use machine-wide. But to uninstall the old version, 5.1, I need to have admin permissions. So I run a script as the system user, but I need to find the installed version 5.4 to verify it exists. However, for each computer, the location of the files and registry settings will be different as it will be installed on a different user profile on each computer.  So I can't use the %appdata% variable, because that will only look in the system user's profile (the default profile, I guess).

How can I configure the verify step to find the 5.4 version of the product on a script that needs to run as a system user.
