Hi looker1
I'm assuming you've installed everything as per the readme and noted the bit about this error in the hints n tips bit at the end of the readme. If you aknowlege the error and just carry on as directed in the readme, does it still not work then? Regarding the regen of the toolpath, this is not really neccessary or particularly meaningful as there isn't really a toolpath to regenerate. The toolpath is calculated on the fly as probe25D.tap is running.
In short just acknowlege (or ignore) the error and run probe25D.tap anyway. Also I'm assuming you've run the probe utilities application on your start menu first to set up the parameters of your choice for probe25D.tap?
Incidentally please be aware that this is not an Artsoft application - the only "guru" involved is me

Get back to me and we'll get it going step by step if you need me - but like I say - please read the whole readme first if you haven't already.
Cheers
