Hallo,
I want to use Advanced installer. But I need to solve this problem :
I need to look for older installation of my product (InnoSetup), if exists, I need to use the old path, if not exists, use [ProgramFiles]\[ProductName] path.
I used searching for folder to property [OLD_APPLICATION]. If older application exists, installation is OK.
But if older installation does not exists, my application installation folder
if "C:\APPDIR\"
How to change "C:\APPDIR\" to [ProgramFiles]\[ProductName] when [OLD_APPLICATION] was not found ?
Sorry for my english and thank you for your help.
Maiad.
