Problem: SSIS 2005 (actually, Microsoft SQL Server Business Intelligence Studio) crashes every time you click on an OLE DB Source to edit it. (there are probably similar errors for OLE DB destinations).
Solution: oddly enough, synchronize a few DLLs:
Version of the assemblies 1msmdlocal.dll1 and
Msmgdsrv.dllmust be the same of the ones installed into “%ProgramFiles%\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies" and the ones installed into “%ProgramFiles%\Common Files\System\Ole DB” location.
If it is not same for any or both of these DLLs, then replace the ones in
PrivateAssemblieswith the ones from
