i have the same problem on windows 7
and the manual regsvr32 does not solve the problem
cd \Program Files\Common Files\system\MSMAPI\1033
regsvr32 /u /s LSMSSP32.dll
regsvr32 /u /s SharingAddin.dll
regsvr32 /u /s ShutdownAddin.dll
regsvr32 /s LSMSSP32.dll
regsvr32 /s SharingAddin.dll
regsvr32 /s ShutdownAddin.dll |
