Hi thealx - sorted it. Yay.

What was in the <E:\Games\Razorworks\> was a clean install of the GOG version. I had then copied this to <E:\Games\Razorworks-1.15.0> and <E:\Games\Razorworks-1.16.0> Then ran the different EECH mods installers (and pointed them to the different folders) to get the different playable versions...

What I did was re-name <E:\Games\Razorworks-1.16.0> to <E:\Games\Razorworks> and then the debug EXE I had compiled in my dev folder fired up fine.

It is probably using the registry entries to look for folders and load stuff, am I correct? Whereas the release version probably gets its stuff from where it is running from?

Cheers
