Hi all,
after system upgrade to Win10 I've been unable to install GOG Galaxy 2.0 (well it's installed but won't open, registry keys point to a totally different application for some reason and I don't know how to change that).
So I tried installing The Witcher 3 via offline files and it was successful, but... I can't run the game, lol. The only .exe files are setup & uninstall, so what do I click to launch the game? A shortcut to W3 was created on my desktop but it only points to a folder with the aforementioned files.
Thanks for your help.

The witcher3.exe is in ...\The Witcher 3 Wild Hunt GOTY\bin\x64 folder

I ran into the same issue - installed the game from the downloadable files; desktop link is broken - it just opens the directory where it was installed. (I installed it on a non-C:\ partition.)

I came here trying to find an answer - thanks for pointing out the location.

Worked for me too. Thanks a lot.

This worked for me as well. Thanks!

I find it strange that this keeps happening, but at least I found the solution thanks to you guys.
