it fail in the

Execute-Process -Path “$($ShareX.UninstallString)” -Parameters ‘/S’ -WindowStyle ‘Hidden’

3

What is value of $ShareX.UninstallString

4

I think it was
C:\Program Files\ShareX\unins000.exe
But think it a general issue. Cause if i pasta above path in directly it works

Think it a general issue with non msi installer exe

[Pre-Installation] :: @{InstallSource=; UninstallString=“C:\Program Files\ShareX\unins000.exe”; UninstallSubkey=82E6AC09-0FEF-4390-AD9F-0DD3F5561EFC_is1; InstallLocation=C:\Program Files\ShareX; ProductCode=; Is64BitApplication=True; Publisher=ShareX Team; InstallDate=20200528; DisplayVersion=13.1.0; DisplayName=ShareX}

Try this

Execute-Process -Path "`"C:\Program Files\ShareX\unins000.exe -Parameters ‘/S’ -WindowStyle ‘Hidden’

Note : between .exe and -Parameters `""

Because there is a space in C:\Program Files\ShareX\unins000.exe

7

The raw path will work but want to use the $ShareX.UninstallString variable so i need to put some “” around it

8 
Try this

Execute-Process -Path "`"$($ShareX.UninstallString)`"" -Parameters ‘/S’ -WindowStyle ‘Hidden’

Because there is an space in C:\Program Files\ShareX\unins000.exe
