Whenever i install a expansion pack it gives me that goddamm error

Before my desktop got reformated due to virus, its win 7 home premium x32 bit.

After it got reformat, the technician installed win 7 ultimate x64 bit...

From than on everytime i install sims 3's expansion pack i get the "unable to start game service initialization failed. (0x0175dcbb)" its really frustrating.

Its fine with the base game alone but if i add a expansion pack it will giv me the "unable to start game service initialization failed. (0x0175dcbb)" error
