vla-GetInterFaceObject Automation error

Most of the machines here run the following code just fine:

(vla-GetInterfaceObject (vlax-get-acad-object) "ObjectDBX.AxDbDocument")

However, there is one that returns this message:

Program error: Automation Error. Problem in loading application(0)

The "vlax-get-acad-object" function works just fine. The
"vla-GetInterfaceObject" function is defined. We're working with AutoCAD
2002.

Last week, the machine with the error had AutoCAD stop working, and after
hours of trying to figure out the reason, that particular problem was solved
by reloading AutoCAD.

Where should I look to find the reason for this error?

Thanks,

Randy

 

ObjectDBX is probably not registered on that machine.Here's a check that I
include in my lisps that will autoregister it if needed.

 

Hmmmm, hit CTRL-V and it sent my reply....strange. Here's the code:

(if (and (= (atoi (getvar "AcadVer")) 15)
(not (vl-registry-read
"HKEY_CLASSES_ROOT\\ObjectDBX.AxDbDocument\\CLSID"))
)
(startapp "regsvr32.exe" (strcat "/s \"" (findfile "axdb15.dll") "\""))
)

 

I had that same code, except for the part about checking for the acad
version. So I was tempted to think that that was not the answer. However,
realizing that AutoCAD had been re-installed since the registry item had
been defined, I deleted the registry item and re-ran the program, and now it
works fine.

So, thanks.
