Hi everyone,

I am getting this error while calling Seagate 8.5 crystal reports from .net code.

OS Win10 32Bit
Visual Studio 2008
Crystal Tool Seagate Crystal Report 8.5.


I Designed Crystal reports in vb6.0 and using dll file via .net code. At windows xp this was working fine, but when I migrated at windows 10 32bit the above error occurs while calling to dll.
Please help me for this issue.

I got error at x.helloVB() line.

at VB 6.0 Project1.dll
Class1.cls
Public Sub helloVB()
Form1.Show 1
End Sub

Form1 contains CrystalReport Viewer Control and no single line of code.

at .net end
Dim x As New Project1.Class1
x.helloVB()


What I have tried:

1. Changed Target CPU to x86.
2. Installed SQL server compact 3.5 sp1.
3. C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE>devenv.exe /ResetSkipPkgs
4. Registered and Unregisterd DLLS.
5. Added Directory permissions to full control.

We can't help you to fix code that we can't see.

Click the green "Improve question" link and update your question with the relevant parts of your code. Remember to indicate which line of code the exception is thrown from.

When you say you have registered and unregistered DLLs are you sure you are not mixing 32bit and 64bit stuff and that you are registering components using the correct version of Regsvr32.exe in each case?
