RobotStudio event

Process "Virtual FlexPendant.exe" not found.

I'm trying to develop an application to run on a flexpendant. I've installed all the sdks at the last version (downloaded from the ABB Site). After installing VS2008 professional, I try to compile a solution but I have the following compiling error::

Errore    1    The process "Virtual FlexPendant.exe" not found.    C:\Users\win 7 64 bit\Desktop\lato_robot\TpsViewHRE_v1.2_5.15\TPSViewTexts\EXEC    Texts

Has anyone an idea to solve that issue?

Thanks a lot.
