I was under the impression that the Enhanced Edition also included the two premium modules, 'Side Effects' and 'The Price of Neutrality'. However, they weren't included as part of my install...

...Am I missing something? Misinformed? Thanks.

In the retail version, all you need to do is click on "New Game", then "New adventures" and they should be listed there. If they aren't, then the GOG version is missing something.

^They are there.

Yeah, I click on 'New Adventures' and when I do, all there is, is a picture of the Witcher symbol on the right, which I can't click (the option to 'Load' is greyed out).

If it's there for you, chautemoc, and you have the GoG version, then I'll try redownloading / installing.

That's weird. There should actually be more than just those two adventures... with the v1.5 patch some user-made modules were added too, so I think there's a total of about five new adventures to play. These are all present in my disc copy of the Enhanced Edition (after patching it to 1.5) and from the forums here it seems that the GOG version should have them too.

Let us know if redownloading / reinstalling helps.

I have all the Premium modules. GoG version, downloaded 4 days ago

Yes, quite convenient piece of software.
Just to be sure, you go to New Game and you only have the option of starting a new campaign? No selection between the Modules and the Campaign?

These are the adventures i have with gog's TW EE.

Same as me.
Please confirm. I find it quite strange you have an older GoG build.

I have the option, but it's as if the modules never installed (and so I can't load anything)...

...HOWEVER, I re-installed and the modules are now showing up. I don't know what the issue is (this would be the second reinstall... I tried once before posting), but re-installing it again resolved it.

Strange. I wonder if it was related to running the installer as administrator or something? Anyway, glad it's working now.
