Visio 2010 'no product key detected'

Hello,

I have thinapped visio 2010 following the sequence guidelines on this site

http://blogs.vmware.com/thinapp/2013/02/thinapp-microsoft-visio-and-project-2010-while-locally-installed-microsoft-office-2010.html

Visio does not activate, when i run 'cscript.exe ospp.vbs /act' within the thinapp cmd. i recieve the message:

'No installed product keys detected'

When I run the installer with the same config.xml and then run the above command the KMS server succesfully activates my Visio product.

Someone got an idea?

thanks.
