Module 'acad/ACAD' is unavailable for use with this FME edition (after upgradet 2024.2 to 2025.0

Please try re-installing FME 2025.0 on your computer. FME and AutoCAD Map 3D share some DLLs that may have been deleted when AutoCAD was uninstalled. Reinstalling FME should fix this! If you continue to have this issue, please submit a support case for us to look into further :)

Hi Evie, Actually I know if I re-install 2025.0 fix the Acad.dll problem. During send the topic I was suspect vhy I got that message. For reason I wrote the on my message a note about uninstall Autocad. But i couldn't think FME used Autocad DLL’s ( is another product). So now I am afraid some different problems about new verison Of FME. Reason allready I am working on a project which must be delivered in short time. After delivery project of course i will do it.

Thank you interested.

Hi ​@omerseyfettin interesting. Could you provide your whole log file and attach it to this thread? I’m wondering if there is anything else going on. happy to help :)

Hi again ​@evieatsafe already i deleted the log file. Delivered Project sample part waiting comments from owner, so i will send finished log file next time.

Dear ​@evieatsafe 

To day i accepted your recomment and reinsall 2025.0 verison. So i got again same error which i wrote before as “Module 'acad/ACAD' is unavailable for use with this FME edition”. After that i tried update which allready use Microstation V8 type reader. I got two error message as attached picture. Both of files already in the C:\Program Files\FME\Plugins folder. So i attached the log file with pictures. Please check it.

Hi ​@omerseyfettin,

From the information in the log file, it appears the ACAD module is not fully loading. I also noticed that FME is not able to add the the System PATH due to its length, which may interfere with loading DLLs.

Please remove all the existing FME and Autodesk related paths from the System PATH, and any others that you can do without. With the smaller PATH, FME will be able to add its required folders temporarily to the beginning, ensuring it has access to all its DLLs.
