VS 2010 Error message on customers computer so program will not run

Hi All

I have never received this message from my customers before, but this one says: 'your administrator has blocked this application because it potentially poses a security risk to your computer '

Currently I have instructed the customer to un-install then re-install the program, make sure that they are logged on as administrator in their user profile also

I am at a loss :confused: as to what other advice to give, your help would be appreciated :thumb:

Thanks in advance
