Command: PLANTREGISTERCUSTOMSCRIPTS

I have tried remove all scripts from the folder and even created a new CustomScript folder but still getting this error.

Is there a way to solve this without reinstall plant3D

Have you already considered the file "custom.pyc"?

I happen to occur the same issue with my client, the root cause is your CustomScripts folder contain invalid scripts (because he install Axelerator plug in and these scripts are broken).

First you need to check where is your current content folder in spec editor: 

Now you check your customscripts folder at: your_content_folder/CPak Common/CustomScripts.

check there and remove all the scripts and add again with try and error to see which one is the culprit.

Another option is just to set your content folder (in spec editor) at different location.

Hope that help.
