Unable to configure Gurtle on Windows 7 x64

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Installed Gurtle 0.6 x64
2. In TurtoiseSVN: Added issue-tracking provider.
3. Filled directory and parameters (options button is grayed out)

What is the expected output? What do you see instead?
the following error message appears:
"The issue-tracker provider could not be created. Please check that it is 
installed correctly."

What version of the product are you using? On what operating system?
Windows 7 x64 - Ultimate
I have installed TortoiseSVN 1.6.10, Build 19898 - 64 Bit and
Gurtle-0.6.0.236-x64.msi (current featured download)

Checked that all requirements are installed:
I have installed .NET Framework 2.0 and UAC is disabled.

Also tried reïnstalling, even to a different path, and rebooting after the 
install, but TortoiseSVN keeps displaying this message.

If there is more information required then please ask, I am a developer myself 
(bluemsx-wii project).

Installed tortoiseSVN and Gurtle on a different computer, with same OS etc, 
there it is working correctly.

I have uninstalled TortoiseSVN and Gurtle from my computer, then reïnstalled 
them, but still the error message...

I have been looking around in source code, the Debug|X64 project doesn't set 
preprocessor definition WIN64, so it receives the wrong GUID!

I have found out that this issue is caused by the windows update: "Microsoft 
.NET Framework 4 Client Profile for Windows 7 x64-based Systems (KB982670)"

After it was working on my second computer, installed this update, and the 
options button was grayed out, and the same message. Uninstalling this update 
on both computers, and both computers are able to configure gurtle again.

I have no idea what breaks it, but it might actually be an issue in 
TortoiseSVN, that it's unable to create the Interface. As I don't have VS2010, 
I cannot debug tortoiseSVN myself.

So for now the workaround is to uninstall the update.
(please don't forget to fix the preprocessor define in Debug|X64, see comment 
1!)

I have KB982670 installed for a few month now and I don't have any problems 
with the x64 version of Gurtle in TSVN. So I don't think it's that Windows 
update that's causing the problem.

Set the WIN64 define for debug x64 builds in r238.

Maybe there is an additional relation with something, but it is the only thing 
I installed & uninstalled on my second computer that broke and fixed it.

On my primary computer I also uninstalled the .NET framework 4 extended (as it 
had to be removed prior to removing the client version)

I don't have any knowledge about how COM objects interact, so I don't have any 
more insight on this matter.
