I've been struggling with this for several days and signed up just to ask this. All answers point to deleting Applink folder and it fixing everything. Unfortunately, that fixed nothing, and I'm getting the same issue. I've tried copying the files from 3DCoat script data to io_coat3d. A 3DC2Blender file was never created, nor was an Exchange_folder.txt so I manually created that. The only thing I can think of that may be causing this is the fact that my Documents is stored on a separate hard drive, but I tried creating 3DC2Blender folder on both drives and it didn't seem to matter. Trying to open project from 3DTextura to original application gives the prompts, but then nothing happens afterwards. Blender gives python errors when trying to export. Here are the errors:
