Current WPF Demo won't start

[Claude]

It seems as though the current WPF demo application will not run. I just tried it, it told me there was a new version, it loaded but won't execute. The version is 2011.3.1116.35 I have uninstalled and reinstalled but it always fails.

The system application log reports:

Hi Claude,

Thank you for contacting us.

It seems that this error is due to installation issue rather than application. Could you please try the following steps:

1. Uninstall the previous version of WPF Demos application
2. Ensure that the folder C:\Users\xxx\AppData\Local\Apps\2.0\6GNG0VC5.4GG\1N029QJT.QB9\wpfd..tion_1d... is empty (if still exist).
3. Reinstall the demos application.

Let us know if you need further assistance. 

Kind regards,
Teodor
the Telerik team

I have uninstalled and verified that the directory is empty (it doesn't exist after uninstallation) and reinstalled and I get the same failure. Previous versions worked well, this version fails.

My machine is Win 7 Enterprise / 64bit.

Thanks
