Check that subfolder exists?

[pwwatson]

Hi,
I want the user to be able to select a currently existing destination folder, then have it check to see if a certain subfolder exists. If it does then files are copied. If it doesn't then the installation is exited with an error. Can this be done with your program?

Thanks,
Paul

Partially.
You may add the following command on the 'System-Commands' page:

Code: Select all

Command: <SystemDir>\cmd.exe
Parameters: /K IF NOT EXIST "<InstallDir>\SubFolder" ECHO "SubFolder doesn't exists."
Show: Normal
Timing: After Installation

This command checks a subfolder existing and then shows a message.
