"%programfiles%\UltraVNC\unins000.exe" /VERYSILENT /NORESTART
If you try to do just /SILENT, there is a prompt to ask you to reboot, so it's really not silent.
In a script, i did it like this:
Directory: C:\Program Files\UltraVNC
File: unins000.exe
parameters: /VERYSILENT /NORESTART
"%programfiles%\UltraVNC\unins000.exe" /VERYSILENT /NORESTART
there was a "n" missing in unins000.exe - bortiz557 8 years ago
