Upgrade from 5.0.3 to 5.0.7 losted add-in

[btsang]

I try to upgrade my laptop from 5.0.3 to 5.0.7 and after the update, the Zimbra sharing add-in disappeared from the trusted center (I am using Outlook 2007). Tried to repair it but still doesn't work. Anyway to recover this?

Thanks

I've tried to run the regsvr32 command suggested by another post ZCO cannot sync outlook calendar which seems not working as well. The return error is "The module C:\xxxx\SharingAddin.dll" was loaded but the call to DllRegisterServer failed with error code 0x80070005". Any idea how to fix this?

I am using Vista 32bit and MS Office 2007. I've tried to use process monitor to find the key but can't seems to locate any. Thus, any particular key I am looking for?

Btw, since I lost SharingAddin.dll, I cannot even send out mail which will report SharingAddin.dll not found error. Any help?

80070005 means no access. Do you have proper permissions to the registry hives?
