Googlando qui e la ho trovato questa procedura, di cui NON conosco l'efficacia
Manual solutionFirst open a run window by clicking start, then run. Now, type the following command and press enter:
regsvr32 softpub.dll Wintrust.dll Initpki.dll Rsaenh.dll Mssip32.dll Cryptdlg.dll
If you use Windows XP you should open another run window after running the previous commands then type the following command:
regsvr32 Dssenh.dll Gpkcsp.dll Slbcsp.dll Sccbase.dll
In previous cases we found Norton Internet Security to be the cause of this error. Normally provided removing and/or reinstalling it fixes the problem.
