Thank you for your suggestion...
I'll explain to you exactly what's happening knowing that I'm running (Win 10 Pro 64b):
The source of the application I want to install is "Anas - Sacc - After Format Programs".
After I launch the setup, and keep on the default folder path for the installation:
If I check the box: Launch the application (after setup); it launches for one time, so if close it and search for it again in my PC; it's not there! (even If I copy during the setup process the target folder where the application is supposed to be) , If I check the same link again; the application is not there; and therefore even if I run the patch as ADMINISTRATOR, it's not finding the application to patch it!
The application name is "VSO Convert XtoDVD"...
In another Instance (Other Protected DVD/Other Application)... The setup runs and the application is there under "Program Files" in my PC... However, even when I'm running the patch as Administrator, I can't change the default folder path to the one where the application is residing "Program Files"?
Would you kindly advise what to do regarding each of the scenarios mentioned above?
