B-Spline crashing Freecad in dev version 0.19

[PJtraveler]

Doing a complete uninstall (used Revo) and then a re-install the problem still exists. I tried with a different mouse and the problem still exists.

Errors after clean install are below:
What else can be done to isolate the error?

?Could the issue be that I have Python 3.8 in my Path before FreeCad, and Freecad seems to be built on Python 3.6?

?Could the issue be that I have Python 3.8 in my Path before FreeCad, and Freecad seems to be built on Python 3.6?

I have been using lots of different versions of FreeCAD for years on both Windows 7 and Windows 10. I have absolutely nothing in any Path (user or system) related to FreeCAD.

At one time I had links to Boost, Python, etc., and they sometimes caused problems.

FreeCAD for Windows is stand-alone. It needs nothing linked from Path.

Gene,
Thanks for your input

I've deleted Python from the system and the problems still persist, although I am now able to move the control points before FC crashes.

Did you ever install FreeCAD? That may do additional things beyond just unpacking.

[UR_]

Can you please test starting freecad using this batch file:

freecad.bat.zip

(188 Bytes) Downloaded 44 times

- unzip batch file into that folder, where freecad.exe could be found.

- double click freecad.bat in file explorer.

[GeneFC]

Did you ever install FreeCAD? That may do additional things beyond just unpacking.

I installed the release version of 0.18, but I did not install any version of 0.19 because there is no installer.

Frankly I do not remember if anything was added to Path when 0.18 was installed, but I had been messing around with Boost and Python as I noted earlier. If anything was added to Path by the 0.18 installer I probably removed it a long time ago.

The point was that there is no need for any FC links in Path.

I also avoid allowing anything to install in the Program Files folder if I have a choice. Windows does all sorts of strange things (protections) to stuff installed there. Of course that means I need to trust that FC is not malware.

Right you are!
Sometimes I get a little wistful when I think that there were times when a program was uninstalled by simply deleting a folder.

[PJtraveler]

The .bat file was a good suggestion !
FC will not start with an empty path!
Graphviz is in the path, I thought FC required Graphviz.

I'll work on isolating what FC needs from the path
