Scenario
User can browse for a directory on the computer. The directory files and sub directory will be copied to the installation location Also check if a file (myprogram.exe) exist in this folder otherwise do not allow the directory files/sub directory to be moved
Need this so, users that have the program before this installer was made can just select the folder where its currently located and can be moved to program files for future program updates.
How can I do this in Inno Setup?
