I'm not sure what you've done wrong because I can take everything in the Galaxy Forge folder and use it (haven't tested on a different computer so it may search for stuff in my steam directory mind you).

You don't need to put any more files in the galaxy forge folder. However, Galaxy Forge does use microsoft's .NET framework, so you likely need to update that if you are having trouble, especially if you have an older PC.

Well, I only copy what's in the GalaxyForge directory and it works fine. 

Yeah, I dunno.  I've tried copying the entire directory now from my main PC over to the other one... still no go.

My .NET is up-to-date.  I have up through and including v4.5 Full installed and Windows update shows no new updates.

Would you like screen shots to prove that?

Yes, I do (link to MSDN site is for reference).

Awesome. Glad you got it working, and perhaps this post will save someone else a headache. 

Alas every program linked to MS Visual C++ libs needs precisely the version of the libraries (dlls) with which it was compiled/linked against, down to security fix version. The way Windows handles this insanity is SxS (side-by-side). Meaning you need to have all the old/buggy versions installed for programs linked against those to work. See http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/multiple-microsoft-visual-c-redistributable/0608a19a-38a8-4885-9eb4-128a2bfad0a3

The GF exe is a "pure" dotnet app, but Ironclad.Managed.dll (which GF exe probably loads dynamically because it's not listed as a static import thereof) is a mixed (there's some official term for this, but I don't recall it now) binary using both dotnet and VC++ 8.0.

I'm not entirely sure if http://www.dependencywalker.com/ lists the actual versions required by a file or whatever they resolve to on my computer, but for the GF that comes with Sins 1.82.5006, its Ironclad.Managed.dll is linked against (or at least works ok with) the libraries of VC++ 8.0.50727.6195. A google search for that version number points to http://support.microsoft.com/kb/2538242 for a description (security bulletin) of that precise version; the actual download link is buried at http://www.microsoft.com/en-us/download/details.aspx?id=26347. In general, it's safe to install multiple/parallel versions of these files, so anybody having this problem should try that link. (In case it's not obvious, you need the x86 variant.)

I'm not sure how quickly the forum updates a post when you edit it, but I've added a precise version of the VC++ libraries [known to work for me with GF], together with a DL link for that.
