missing python modules

Again, no dice. The F-Engrave version I'm trying to run is 1.75 and It will not execute on it's own, only from within a P3 development environment. It is designated as an executable file. I've done four complete removals and installations with fresh files each time, always with the same result. In a terminal, I get the missing pyclipper statement but pyclipper has been installed.
I'm wondering if I have a problem with my PYTHON3 installation. Can it (PYTHON) be safely removed and reinstalled without cratering everything else?

I was only trying it by calling it from python3 rather than trying to run it directly.

To run it directly you need to:

1. Change the first line to python3 as Tommy pointed out in a previous post.
2. Change the line endings in the file from Windows type to Unix type.

Yes, I added a "3" to "python" at the header of the main script when he suggested it (!#/usr/bin/python3) and I've always been making the suffix change using sed -i.bak 's/\$r\\' from the terminal. I finally decided to try an earlier release of F-Engrave (1.74) which doesn't run but it does give me some new error messages which seem to point back to the Launcher_py script. It says it can't lauch STARTUPINFO.
It's not worth the headaches of getting this far into the weeds over an engraving program that's already running on another computer. The answer to the question of whether python can be safely removed and reinstalled without damaging any of the CNC programs' workings should have some value though. Can it be safely removed and reinstalled or no?
Your best educated opinion?

Ugh. It would appear that I have some terminal flaw in my Linux installation; it's now crashing randomly and the menu header no longer responds. Lucky me.
Probably explains the python headaches...
