Gersen: If tomorrow GoG decide to switch to an installer that doesn't have an available extractor you could lose this "feature" altogether.
That is an excellent point. GOG is not providing me with the service I want for most of my purchases, they actually never did, I have no reason to complain (except my own foolishness) and since i'm unwilling to go through the only officially supported path (find a machine running windows, install there the thing and transfer back the required files) i should just stop ruining your fun.
Gersen: But the thing with the way how vague DMCA is worded is that it could also perfectly apply to using InnoExtract to extract the regular installer, nowhere in the EULA it is said that you are authorized to do that
Another excellent point, I never assumed I was probably breaking the law by tampering with the installer, the new TOS just makes it clearer. Again, no reason to complain on my part, actually I'm the one that should probably make an apology, and i certainly won't repeat my mistake. Ever.
