Module 'realdwg/REALDWG' is unavailable for use with this FME edition (FME Flow 2024.2)

After upgrading FME Flow to 2024.2 some of our workspaces fail with the following error:

  • WARN  |Library 'F:\FMEFlow\Server\fme\plugins/realdwg/REALDWG.dll' was found but could not be loaded. Ensure that all the dependent modules exist for this library
  • WARN  |Could not load module 'F:\FMEFlow\Server\fme\plugins/realdwg/REALDWG.dll' : 'The specified module could not be found'
  • WARN  |Could not load module 'F:\FMEFlow\Server\fme\realdwg/REALDWG.dll' : 'The specified module could not be found'
  • ERROR |Module 'realdwg/REALDWG' is unavailable for use with this FME edition

Seems like RealDWG and AUTOCAD_OD readers/writers do not work anymore.

 

-Is this a known issue/bug?

-Is RealDwg not supported anymore? It does work in FME Form 2024.2

It seems there might be a problem in the FME packaging of 2024.2.
Checking the dependencies of realdwg.dll in FME Flow the following shows: 

In the screenshot the dependencies compared to the plugins folder, where apparently older dlls are installed.

To fix this, we've copied the fme\plugins\realdwg folder from a FME Workbench installation which contained the exact same realdwg.dll as FME Flow with ...25.dll dependencies, but also the correct ****25.dll files.

This is in FME Flow 2024.2
Build 24783 - win64

It’s an old one, but I wonder if this question/answer is related

Can you confirm that the dll’s in Flow are older than the ones in a Form with the same build? If that is the case it seems to be a pretty major issue.

That's correct.
The build number for both Flow and Form is 24783.

The software version does show 7.46.24783 for Flow and 7.51.24783 for Form.

Interesting! ​@jovitaatsafe could you look into this?

Hi All,

This issue has been fixed in FME Flow 2024.2.1, which will be available for download on Dec 5.

I upgraded to 2024.2.1 on the 12/17/24 and I am seeing this issue so it appears to not have been fixed.

Hi ​@tjc_cows,

I installed Flow 2024.2.1 on a clean pc, and tested writing with RealDWG. It seemed to work OK.

Please send me the log file from your copy of Flow from a failed run, and I will try to find the source of the failure.

Hi ​@daveatsafe,

Update: I installed Flow on a new Windows Server 2022 and now I am getting a different error that I can’t find anything about.

 

Error happens at the PloygonBuilder: AutoCAD Reader: An error occurred for dataset ..., in function AutoCAD2004Reader::read. Exception thrown: 'Invalid ResBuf' (Invalid ResBuf)

Hi ​@tjc_cows,

I think we will need to reproduce that error here to see what is causing it. Please submit a ticket at https://support.safe.com/hc/en-us/p/support, and include a copy of the DWG file triggering the error.
