After upgrading Visual Studio 2005 to 2008 we started getting problems with Crystal Report on a few machines (unfortunately I haven't been able to replicate the problem on my own computer)

The problem happens when creating a report. I get the following exceptions:

Message: Object reference not set to an instance of an object.
StackTrace:    at CrystalDecisions.CrystalReports.Engine.ReportClass.Dispose(Boolean bDisposeManaged)
   at CrystalDecisions.CrystalReports.Engine.ReportClass.Finalize()

And

Message: The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception.
StackTrace:    at CrystalDecisions.CrystalReports.Engine.ReportDocument..ctor()
   at CrystalDecisions.CrystalReports.Engine.ReportClass..ctor()
   at Andresen.rptQrapport..ctor()
   at Andresen.Applications.Qsys.Tools.QrapportGenerator.MakeReport()

The computers where these exceptions occurs does have the version of Crystal Reports that comes with Visual Studio 2008

Does anyone know what could be the problem?

I don't know, but I see that one error is being called by the MakeReport() method. Is it possible that the user doesn't have full Admin access to all the folders and therefore can create the temporary files necessary to bulid the report? Just a hunch.

The users has the same rights as before we converted to VS2008 and all users has the same rights, but not all users gets this problem

MakeReport looks like this:


private rap as CrystalReport1
Private t As New List(Of Test)

public sub new(lst as list (of Test))
        t = lst

        MakeReport
end sub

private sub MakeReport
        rap = New CrystalReport1

        rap.SetDataSource(t)
end sub

Still having this problem

The exception is thrown in this line:

rap = New CrystalReport1

And New() in CrystalReport1 looks like this:

Public Sub New()
        MyBase.New
End Sub

Which makes it very difficult to something in code to avoid this. CrystalReport1 is an empty document, so no fancy features in that one

Nobody? This problem is driving me nuts

I tried reinstalling Crystal Reports on the machine, but no luck

After doing a quick check on the source code for the report class I noticed nothing special. No sign of where it could throw an exception. The inner exception message says the exception is thrown in a Dispose method of the report class, but why is Dispose called during initializing of the report document? On my own computer (importing the source code from report class to debug that area) debugging through this report class shows no sign of wanting to dispose anything

This problem is still haunting me, so I tried using FileMon to see what was going on when the report is made

What we know so far:
When the Administrator logs in, the report is created without any problems
When a user logs in, the report fails during Sub New

So using FileMon on the same machine, one as Administrator and one as a user I found these differences:

Administrator:
85    10:47:37    csrss.exe:508    QUERY INFORMATION    C:\Programmer\Business Objects\Common\2.8\bin\da-DK    NOT FOUND    Attributes: Error    
86    10:47:37    csrss.exe:508    QUERY INFORMATION    C:\Programmer\Business Objects\Common\2.8\bin\da    NOT FOUND    Attributes: Error    
87    10:47:37    csrss.exe:508    QUERY INFORMATION    C:\Programmer\Business Objects\Common\2.8\bin\    SUCCESS    Attributes: D    
88    10:47:37    csrss.exe:508    QUERY INFORMATION    C:\Programmer\Business Objects\Common\2.8\bin\    SUCCESS    Attributes: D    

User:
90    10:24:44    csrss.exe:508    QUERY INFORMATION    C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\da-DK    NOT FOUND    Attributes: Error    
91    10:24:44    csrss.exe:508    QUERY INFORMATION    C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\da    SUCCESS    Attributes: D    
92    10:24:44    csrss.exe:508    QUERY INFORMATION    C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\    SUCCESS    Attributes: D    
93    10:24:44    csrss.exe:508    QUERY INFORMATION    C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\    SUCCESS    Attributes: D

A clear difference is the folder used here. In the working situation in uses Business Objects folder under Program Files, the not working situation it uses the Framework folder in Windows

Also in the working situation it calls a file called Microsoft.VC90.ATL.mui.DLL, while when it doesn't work it uses Microsoft.VC80.CRT.mui.DLL

And remember this is the same computer, only difference is user rights

What was you solution to this Adagio?
I seem to be confronted with a similar issue, however it's not different users which are affected, rater different applications, run by the same user on the same PC.
One works fine, while the other gets this reference not set exception on crystal reports instantiation.
