wwgmtk toolkit dll failed to load

Hello,

I'm trying to get the wwgm toolkit to work. I compiled the "hello world" example.

I'm compiling this with "microsoft visual C++ 2010 Express" and the build is successfull.

The customizationTK.xml file is also ready with this line in it.

<customization name="testtoolkit" path="C:\PTC\wgm\test2\toolkittest\WWGMTK_PROJECT_NAME.dll"/>

Then I start our workgroup manager and I get following error:

<Failed to load testtoolkit DLL from : C:\PTC\wgm\test2\toolkittest\WWGMTK_PROJECT_NAME.dll.>

I'm not able to solve this problem. Does somebody know what I am doing wrong?

Thanks in advance
