I have tried installing windows service Pack 1 on my systems but could not. While it installing, it suddenly terminated and brought an error message " A required is not within its validity period when trying against the current system clock or the times tramp in signed off''. I read it on this site that I should install SUR for 32 Bit for my system . While trying to install this again, it stopped and brought another message " CERT_E_EXPIRED (0x80060101'' . I further downloaded HOT FIX to see if this will work but did not. How do I do this? I can not do update on my system and do not want to start a fresh installation either. I have tried so many options but could not.
How do I resolve this? Please this is urgent.
