Two versions of DLLs being loaded

[Former Member]

I am having a problem with this line in my code:

Dim myReport As Report = CType(myInfoObject, Report)

The error I am getting is:

Unable to cast object of type 'CrystalDecisions.Enterprise.InfoObject' to type 'CrystalDecisions.Enterprise.Desktop.Report'.

I have references in my project to

CrystalDecisions.Enterprise.Desktop.Report

CrystalDecisions.Enterprise.Framework

CrystalDecisions.Enterprise.InfoStore

According to their Properties, they are all version 10.0.3300.0.

In the output at the bottom of my Visual Studio IDE screen, I suspect the problem lies here:

As you can see, it is loading DLLs from both version 10.0.3300.0 and 12.0.1100.0. How do I fix this?

Check the web.config file. The references should be there and you can delete the unwanted assemblies.

I checked the web.config and couldn't find any assembly references for some odd reason. However, I removed the version 10 references in the project and referenced the version 12 objects instead, and the problem was solved.
