Tech Tip: Why your plug-in may be loaded but disabled
PRODUCT: 4D | VERSION: 2003 | PLATFORM: Mac & Win
Published On: June 6, 2003
The obvious reason is you do not have the license to use the plug-in.
The not so obvious reason is you are on Windows but have the Mac compatible version of the plug-in in the MAC4DX folder and do not have a Windows compatible version of the plug-in in the WIN4DX folder or vice versa. In this case, 4D will load them and disable them.
