Hello everyone,

I have installed 0.18 and it worked fine on windows 10. Now I cannot launch it anymore. Any ideas what can be wrong?

Err: Exception (Wed Jul 31 13:38:46 2019): Access violation

We have seen the last message "Access violation" in connection with graphics cards / drivers and Qt5. Did you (or some automatism) install an update of your windows? If so I would recommend that you use a current 0.19 Qt4 version.
If not try to delete your config files or to move them in case you want to restore them.

To improve readability of log output you should use the code tags </> around your listing.

[giedrius9999]

...do you meanto install 0.19_pre ? or another one?
...neither can locate configuration files in appdata/FreeCAD...

[giedrius9999]

FreeCAD_0.19.17352_x64_LP_11.11_PY2QT4-WinVS2013 doesn't run either

[kisolre]

What graphic card do you have on that PC?

[giedrius9999]

Intel(R) HD Graphics 520

[kisolre]

If this is the only graphics card in your PC it might be hard. Results from here https://duckduckgo.com/?q=HD+520&sa=Sea ... org&ia=web suggest that upgrading or downgrading your graphic card driver might help.
Also you could try with FreeCAD_0.19.17651_x64_LP_12.1.2_PY3QT5-WinVS2015.7z
LP 12.1.2 uses more recent Qt 5.12 which fixes some issues. Not idea if it will help in your case.

FreeCAD 0.19 works well!

Many thanks!

[giedrius9999]

...few months before could not launch 0.18 on Windows 10...then, tried with 0.19...it worked wel for a while...then crasched again and I switched freecad to personal computer.
Now, self quarantined sitting at home and working from home...have to try again. Tried with FreeCAD_0.19.20209-Win-Conda_vc14.x-x86_64...cannot launch...then tried with
FreeCAD_0.19.20311_x64_LP_12.1.2_PY3QT5-WinVS2015...and launched finally!!!!
...after two hours crashed...cannot launch anymore!!!
...what hell can it be???

I would recommend a full reset of the configuration by deleting your config files (see above).
