I am using this hook to inform the user that if s/he chooses to include Program Files folder in the path of the installation folder, s/he will need to Run as Administrator to run our program in Vista.
I am using MessageBox MB_YESNO|MB_ICONEXCLAMATION ... and give him/her an option to revert to the default installation directory if s/he presses YES. However, it does not get displayed in the Install to... text box. I use StrCpy $INSTDIR C:\SuperMemo
How can I update the text box with the default installation dir??
