Activation after installation Intel Matrix Media Manager 7.6

Installation of Version 7.5 of the Intel® Matrix Storage Manager couses vista
deactivation and impossibility of online activation.
I recieve error - product key already in use -
windows event - hardware changed - grace period to automatic activation 3
days.
Online activation is not possible, of coz I can activate by phone, but I
dont want activate by phone every time I reinstall vista.
Same thing when i install manager before activation or after.
Is any method to bypass that problem???
