Intune Package uninstall failure on uninstall assignment

Hello,

I'm new to this community. Having an issue with Intune and the uninstall assignment with a particular program. Up till now its all been pretty straight forward, write up a batch installer/ uninstaller, package the app, assign the install uninstall commands, and then publish to Intune. 

The issue is with Bluebeam Revu 18. The company provides an uninstall script but it does not seem to be working in Intune. When you package it up and go to test on the test environment, it keeps failing the uninstall. I was wondering if there were limitations to the amount of commands Intune could run during the uninstall process or if there are certain commands that cant be run. Please see the script below.
