Jeku,
Because I had installed Windows 7 from scratch, there were a crock load of updates to download, but this was my first step to ensure all was up to date.
I then downloaded from Microsoft, the DirectX SDK v9.0c (August 2009) The whole download was 566mb
Because of User Access Control causing several problems on other developments at work, I turned this off under User Account management, and did this before installing any of the major stuff below.
Although I've since installed VS2010, At this stage, I installed Visual Studio 2008. Now, not sure if this is important for the DarkGDK.NET installer, but installing Visual Studio 2008 pretty much garuntess that the Visual Studio Runtime files are preinstalled as well, which may well be what people are having trouble with sometimes.
I then installed the DirectX SDK which went in no problem.
I installed the DarkGDK.NET toolkit from my last build which is what is currently distributed by TGC, no changes made.
I also installed the Game Creator Store application as part of the installation process.
Now although I had not ran up any project workspaces at this point, I did run through the preinstalled demos, and all of then ran without any problem on Win7 64bit.
If you can get this far without any crashes, then we're on the home stretch.
My personal opinion, is that both UAC must be off before installing any of the above because even when it's on, it changes the overall configuration of the development tools as well. Also, the VS Runtime stuff was pre-installed as well which may make a difference.
Can you let me know if you've had any success since my last post?
Paul.
