Hi,
On installing CodeXL on a system that already has VS2010, "Teapot" sample is copied at the following location:
"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\AMD\CodeXL\Examples\Teapot".
"AMDTSamples.props" file is also present in the same location.
You need admin privilege to make modifications to this sample from VS2010.
And looks like for this reason, you have copied the files to custom location i.e. "D:\Users\klijn\...".
copy the entire "Teapot" directory and build it. cross check your VS project settings once.
Hope this helps.
Thanks,
Kalyan P
