How do I check if file exists in the install folder

[iancook]

Hi
I am sorry if this has been asked before...

I would like to ensure the user has selected the same folder that another program is located in.
Ideally this would be done as part of the user interface so the user can go back and select the correct folder.

For example, the install folder must contain "footytip.exe"
If not, then setup cannot continue.

I have attached a screen dump of my attempt to test this in the script but it is not working.

Can anyone please tell me where I am going wrong?

Thanks in advance

Ian
