Hello,

When I try to install the latetst version with the MSI package I get this message:
Module C:\Program Files\Genius@work\Geniusconnect\OutlookInterface.dll failed to register. HRESULT -2147024770. Contact your support.

Also the normal installation doesnt give any errors but I cannot register the addin into Outlook 2007.

I use XP with admin rights.

Do you mean the .exe installation, with the "Normal installation"?

Can you try to run regsvr32 manually in the installation directory:
regsvr32 GatWCrypto.dll
regsvr32 DBContact.dll
regsvr32 OutlookInterface.dll
regsvr32 OutlookConnect.dll
regsvr32 GeniusNTLog.dll

Do you have latest XP service pack (3)?

GatWCrypto.dll is fine
DBContact.dll gives: LoadLibrary("DBContact.dll") failed - The specified module could not be found
OutlookInterface.dll gives: LoadLibrary("OutlookInterface.dll") failed - The specified module could not be found
OutlookConnect.dll gives: LoadLibrary("OutlookConnect.dll") failed - The specified module could not be found
GeniusNTLog.dll loads also fine

I use SP3 yes, with all updates installed for Office 2007 and windows.

Can you send us your email to info at geniusconnect.com, we will send you a GotoMeeting invitation and check your PC remote

Running C:\Windows\System32\fixmapi.exe worked! It somehow recreated the mapi32.dll file.
