Thanks everyone for all the good information on this subject!
I'm also looking for Cerec Software Version 3.8. The only thing I've been able to find online is CERECinLabCEREC_Connect_V3.65. And I can't get this to install. I get the following error: "The InstallScript engine is missing from this machine." I've tried everything I know from trying to install the correct InstallScript file to attempting to install the Cerec softwware on a different computer. No luck, and ultimately I don't think this would be the right software for me anyway.
My goal is to be able to convert Cerec scans to STL files. If I'm understanding correctly, I should be able to receive a dxd file from a Cerec user, convert it to a cdt file using 3.8, import the cdt file into Blender where I can save it as an stl file. That's the plan at least. If I'm missing something, I would appreciate any guidance I can get.
If the disk image of the 3.8 software is still available, as mentioned a year ago (above),I would really appreciate a link.
Thanks in advance!
