FreeCAD closes on startup

[gwlindberg]

I have downloaded the FreeCAD-0.20.1-WIN-x64-installer-1.exe, to install on a Windows 10 Pro system with 16GB on Ram, unknown graphics card. The installation completed successfully. When I try to start FreeCAD I see the startup splash screen for a bit with the initializing messages across the bottom and then the splash screen goes away and I get nothing else. I've tried starting FreeCAD from a command prompt to see if there are any error messages, but it forks quickly and there are no messages. I also can't find a log file with any output.

Is there any way to get more debugging output so I can trace what is happening?

Regards,
Greg

Start FreeCAD with the additional commandline parameter --write-log and find a logfile in your local FreeCAD folder %APPDATA%\FreeCAD.

I'm getting a bunch of errors like this:

This looks like at least some of the problem is that I am missing some libraries. Are there some things that should be installed before FreeCAD?

I have a similar problem. I click on the FreeCAD icon, computer thinks for a second or 2, and then the program shuts down. When I go to task manager I don't see the program. I don't know if it matters but I had the same problem when I tried to use Fusion 360. I tried installing Python. I did a sfc scan, whatever that is. I reinstalled windows c++ redistribute. Nothing worked. I'm attaching my log file.

Thanks

I'm getting a bunch of errors like this:

For some reason the QtWebEngine module doesn't work correctly. It's hard to say why this happens.

A workaround is to remove the folder StartPage from the Mod directory. If this still doesn't work then also remove the AddonManager directory.

The log output is too unspecific and just lists a lot of dlls but doesn't really give a clue about the underlying problem. At the very end then it reports an access violation (ExpCode: 0xC0000005). You can try the tips from above but I don't expect it to work here since you have the same problem with other CAD software.

Another often seen problem on Windows is the graphic driver. So try to update it to a newer version.

I had similar problems when upgrading to a newer Windows version some weeks ago.
I turned out to be not having the splash screen enabled.
I installed (unzipped) an older version I knew was working OK, enabled the splash screen in preferences. Newer version have run OK ever since.
Some rescent version has broken the flash screen when disabled.

I'm running Windows 10 with 16GB memory. Mine crashes as well after downloading 0.20.2. It worked fine on 0.20.1

THEN.... I reinstalled 0.20.1 and 0.20.1 started to crash when starting. Now I can't get either running.

Apparently, something 0.20.2 installed is not coming off the computer and hanging around to affect 0.20.1... I can't get any other debug info, as it doesn't stay running long enough to capture anything useful. Just sayin'

Start with the additional commanline parameter --write-log. It creates a log file in %APPDATA%\FreeCAD\

I sorta figured the CLI out and how to get the APPDATA folder. Lemme see if I can figure it out. I have alzheimers and it is very difficult to do the simple things these days.
