Twinmotion Datasmith Exporter plugin for Archicad - Twinmotion

I had a problem installing the latest version of UnrealDatasmithArchicadExporter_5_5_3.
During the installation I got this message:
"the specified account already exists" and the installation was aborted.

To solve this problem, I think you should first uninstall the older versions of UnrealDatasmithArchicadExporter_x_x_x.

OK, but I couldn't uninstall all of them that easily.
For example, I couldn't uninstall the version UnrealDatasmithArchicadExporter_5_0_1.

I searched, read forums etc. to reinstall the old version UnrealDatasmithArchicadExporter_5_0_1.msi and then uninstalled it.

Well, yes - but if I don't have this installer on my disk anymore, where could I download this old version of UnrealDatasmithArchicadExporter_5_0_1.msi? Epic Game doesn't provide it in the official repository. 😕

So, having no other choice, I tried the "atomic option" ! AND IT WORKED !!!

In the Windows registry I found "UnrealDatasmithArchicadExporter_5_0_1" in two places and deleted the entire key (and the parent key).

 

Then I restarted the system and installed UnrealDatasmithArchicadExporter_5_5_3.msi without any problems! 😃

note! everyone performs registry operations at their own risk!
