Apparently, Windows 11 WILL NOT allow DesignEdge v. 4.54 to be installed onto the PC, and installing DesignEdge v. 4.53 onto a Windows 11 PC is a real fight! The Geek Squad at Best Buy has to FIGHT with the o/s to install DE v. 4.53 onto a PC with Windows 11 software on it.
Apparently, PlasmaCam offers NO SUPPORT for installing their latest software onto PCs that are running Windows 11.
I am being told that PlasmaCam's answer is, "That is your problem... go get your computer fixed ... "

If Windows 11 will not allow DesignEdge to be installed onto a PC using that operating system, then Houston! We have a problem!
I sincerely HOPE that PlasmaCam will not kick the can down the road and "solve" your problem by telling you to go find a good Windows 10 PC and install DesignEdge onto THAT PC. That may work for a year or two, but eventually, people will begin to move up to Windows 11, RIGHT?
I don't have a Windows 11 PC here in my home. But I am going to update ONE of my Windows 10 PCs to version 4.54 to see what changed, IF ANYTHING. I suspect that a move from 4.53 to 4.54 is little more than another effort to prevent software piracy, or whatever. PlasmaCam never gives us a README.TXT file telling us what changed, or what was added or omitted with the new version. We are just supposed to install it and remain silent.
I darned sure HOPE they have NOT killed the ability to web conference with DesignEdge via ZOOM or the other online meeting software. PlasmaCam killed TeamViewer a few years ago. I understand why they did that, but it sure made it difficult to help people with the software over the Internet.
The adventure continues ....
