Did you try debugging it?

In which line do you get the error?

[kerry_w_brown]

acadApp = CreateObject("AutoCAD.Application.18.1")

are you accessing

18.0

18.1

18.2

??

Hi,

Using the version independent program id as “AutoCAD.Application” should invoke the last run version of AutoCAD.

So you may want to check which version of AutoCAD was invoked just before you run this code.

If not you can mention the prog id of a AutoCAD version that you specifically want to launch.

Ex : “AutoCAD.Application.18.1” for AutoCAD 2011.

Using the registry editor open the following key and note the CLSID :

“HKEY_CLASSES_ROOT\AutoCAD.Application\CLSID”

For ex : If the CLSID is “6D7AE628-FF41-4CD3-91DD-34825BB1A251”

Look for  “HKEY_CLASSES_ROOT\CLSID\{6D7AE628-FF41-4CD3-91DD-34825BB1A251}\LocalServer32”

The path to the executable that will be launched when “AutoCAD.Application” is specified can be verified here.

Be careful while working with the registry editor.
