Hi Klaus
I have deinstalled the plugin and downloaded and reinstalled V3.02 again. It produced the same result of "Plugin dll defective".
It may not be relevant, but I noticed that about halfway through the installation, I always get asked to repair Microsoft Visual C++2010 x86. I followed the instructions to repair this, including a reboot, and I got the message that it had been successfully repaired. However, when starting Mach3, I get the dll defective messages again.
Regards
David
