ApprenticeServerComponent.open, Inventor 2019 files and windows accounts

[sellis]

We have run into a problem with 2019 files and a VB.net excel addin (windows 10). It works with 2018 idw files but errors on Inventor.ApprenticeServerComponent.Open when opening a 2019 idw.

Dim oApprentice As New Inventor.ApprenticeServerComponent
Dim oApprenticeDrawingDoc As Inventor.ApprenticeServerDrawingDocument = oApprentice.Open(FilePath)

If I log into a computer as network administrator it works fine. Does not work with A user with administrator rights.

I have disabled UAC in the registry with no luck. Could be something funky with our network...

Any suggestions?

Thanks

@sellis,

There might be due to Inventor 2019 register issue when others login. I mean, others login might launched Inventor versions like Inventor 2018 or below versions. Due to this, Inventor 2019 files can not be opened in older versions.

To avoid this, make sure that Inventor 2019 is launched and closed. Now, Inventor 2019 apprentice is available to access Inventor 2019 files.

32 bit applications are not supported in Inventor 2019 apprentice API.

Thanks and regards,

As I earlier wrote:

"Have you set the correct inventor 2019 reference in your project from the add in?
Has inventor 2019 registered correctly? This means open inventor 2019 on all machines and with all users (Admin.)
If not. Open inventor 2019 as administrator and try again. "

I can reproduce the problem with the tool, and I find the problem should be that the Inventor 2019 removes the support to Apprentice x86 bit, and so the tool needs to be recompiled to support the x64 version only, so you can open the VB project, and in the Properties of the project, change the Target CPU in the Compile tab to x64 like below, or AnyCPU but make sure to uncheck the Prefer 32-bit option, then recompile it and check if it works:

Recompiled and discovered the computers that did not work originally have office 365 32bit. That was likely the root as mine is 64 bit and worked. Never occurred to me that they would have 32 bit installed. So switched one over to office 365 64bit and the addin runs.

Thanks!

Curious how logging in as network administrator worked unless it was not pointing to the 2019 files. Between the mapped drives and syncing I could have been trying week old files... 

Anyway, Thanks again.
