Archive: how do you know if a program was installed before testing again the installer?


how do you know if a program was installed before testing again the installer?
i have a multiple installer and i wanna know at the finish page if a specific program was or was not installed. i must specify that if the app is already there, the installer will pass to the next one. but on the finish page i have to show what was installed and i cannot figure it out how to tell the installer that if the specific program was installed, not to show the label with it's name on the finish page.
Thank you!


During installation, write to temporary text file what programs have installed and read it on finish page pre function.


thank you :)
