AutoCAD Type Library Version conflict

Hi guys,

I've installed AutoCAD 2005 to evaluated the new features, but now when I call a new session of AutoCAD from a 2004 session, 2005 is launched. I assumed that I would just need to change the reference back to the 2004 Type Library, but it doesn't appear in the list.

Does anyone know how to get it back to launching 2004?

Thanks,
Mick.

 

Hi Mick,

try the following and I think it should work

Dim obj As AcadApplication
On Error Resume Next
Set obj = CreateObject("AutoCAD.Application.16")
If Err <> 0 Then
MsgBox Err.Description
End If
obj.Visible = True

I do't have multiple session on my system so that I can test it but it should work. Si the difference in the string of CreateObject method. Here you need to pass the version as wel. Just let me know whether it is working or not.

Lots of people have come across this problem.

Autodesk didn't bother to warn them about it, or
provide instructions on how to fix it.

Have you tried launching AutoCAD 2004 manually
before you try to launch it from code?

Second, are you using "AutoCAD.Application" as
your class name? If so, try changing it to the version-
dependent progid ("AutoCAD.Application.16"). The
version dependent progid for 2005 is the same, with
the exception that the '16' becomes '16.1'.

session, 2005 is launched. I assumed that I would just need to change the reference back to the 2004 Type Library, but
it doesn't appear in the list.

 

Hi Manoj,

Thanks for the try. Unfortunately, it still opens up 2005.
Any other ideas?

Mick.

 

Tony,

I'm now using "AutoCAD.Application.16", but still having the error. And it's getting even more annoying. I'm finding that when I update older macros, they work fine on my computer (in 2004, but with 2005 installed), but don't work on any machines that only have 2004 installed. And these macros don't do anything about opening a new ACAD session.

This is one VERY annoying problem. I don't think I'm particularly fond of AutoCAD 2005 any more!

Mick.

 

Replace the acax16enu.tlb on your machine with the one from one of
the 2004 machines then update your references. Even a 2005 trial
install/uninstall will leave this file on your box.
