Very confused about paths

[erm3nda]

Build starts but Im not understanding what Im doing wrong.

Output:

Error on line 35 in Z:\work\setup.iss: Source file "Z:\work\program.exe" does not exist.
Compile aborted.

How should I define paths in the script, and in the iss config ... I am tied to use a static folder name?

Thanks

Please, provide your full .iss script, if you can.
