Hi Phil, unless another user jumps in with the solution, I'm afraid that this one would best be submitted to
support@thumbsplus.com (be sure to put 'ThumbsPlus' in the subject line).
I have managed to install it in TP7 but not TP10. I've tried copying the plugin's files to the Thumbs10 'BIN' folder (where other plugins reside) but that didn't activate the texture plugin in TP10, so, apparently something else has to be done to activate them and I have no idea what it is..
