I’m trying to only uninstall an application called Smartview, however it will not uninstall (uses /x parameter). I have ran/tested the script multiple different ways in the psappdeploy script which all have worked when running locally to test.
Once I upload to either SCCM or Intune (intune winap32 converter), its as if they completely skip over this verbiage to uninstall. I tried to include the uninstall language (pasted below) in the pre-install without luck then tried the post-install without luck.
One thing I was struggling to get working properly was having the .ps1 script to to do the uninstall located in the SupportFiles folder, then calling out that ps1 to use that in the pre or Post install section. I know it involves the $($adtSession.DirSupportFiles)\filename.xxx but can’t seem to figure out what I’m doing wrong.
Any tips would be great. Maybe I’m going about this the wrong way…Below is my script to uninstall smartview.
