Application vanishes when trying to invoke an OLEDB provider with VB6 Form

I have to use an OLEDB provider (for Sungard Investran) from my crystal reports in Winforms Application. Using .Net 4, Crystal Reports for VS2010. The OLEDB Provider has a Parameters Dialog, which I believe is developed in VB6. When I call this OLEDB provider with Queries without any Parameters, it works fine. But when calling any Query with Parameters, the entire application just vanishes. Everything Works fine on Windows XP but has this issue in Windows 7. The app is compiled for x86 platform only. Tries with "all platforms" too, s开发者_如何学运维ame issue. I see two errors in the Windows Event Log

* Error 1

Application: MyApplication.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: exception code c0000005, exception address 071116C0

Any Pointers to Fix this issue is highly Appreciated.

Found a solution hard way. We need to set uiaccess=true in the manifest. Guidance is provided on this thread. Caveat is that it is very annoying as there are lot of restrictions around this solution. But it works though. Welcome to the world of x64.
