checking previous installation during setup

Post by roja2 »

Hi,
Can any body have any idea how the check_install.exe, that comes with
uvnc installer is implemented?
It stops current installation if previously installed service is running.
If somebody could provide source code for it i would be very happy
Regards
Roja

Actually single instance is maintained by creating mutex of the application.
But thanks to innoset up, we can just set a variable named
"Appmutex = XYZ" in innoset up that stops installing another instance while previous is running :)
