I'm unable to use SSIS packages after installing SQL Server 2005. Specifically when I first loaded a new Integration Services project in SQL Server Business Intelligence Development Studio the default SSIS package could not load, I get Package.dtsx in my tabbed document view but in the body of this window is a error message: "Microsoft Visual Studio is unable to load this document. QI for IEnumVARIANT failed on the unmanaged server."
If I try to use the SQL Server Import and Export Wizard shortly after the window to select your data source I get a pop-up error message:
This wizard will close because it encountered the following error:
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft%u00ae+Visual+Studio%u00ae+2005&ProdVer=8.0.50727.42&EvtSrc=Microsoft.SqlServer.Management.UI.WizardFrameworkErrorSR&EvtID=UncaughtException&LinkId=20476
ADDITIONAL INFORMATION:
QI for IEnumVARIANT failed on the unmanaged server. (CustomMarshalers)
Anyone have any ideas on how I can resolve this?
I have experienced the same problem. Have you found a solution yet?
I found other users experiencing similar problems, but apparently not the same issue. I tried the fix at http://groups-beta.google.com/group/microsoft.public.dotnet.framework.setup/browse_thread/thread/a2ed96d68cb349f3/db810a1bcf8f66e4?q=qi+ienumvariant&_done=%2Fgroups%3Fhl%3Den%26lr%3Dlang_en%26safe%3Doff%26c2coff%3D1%26q%3Dqi+ienumvariant%26qt_s%3DSearch+Groups%26&_doneTitle=Back+to+Search&&d#db810a1bcf8f66e4
but had no luck.
