solved: DLL load failed: Invalid access to memory (V.19)

[byakk0]

Ack...
I recently installed Freecad on my home pc. I've been using it at work and until recently haven't had a use for it at home...
Anyway, it was working just fine, and then my system crashed. Now I get a blank loading screen and the following errors.

FCfailed.png (22.24 KiB) Viewed 1709 times

I've restarted my PC a couple times, but nothing has helped.
Any ideas?

Thanks!

First guess is a (silent) update of your operating system, which is worth a look at the Known OS specific issues, especially the graphics card related stuff.

Next would be a test of 0.20. With its different libraries it is well possible, that the problem disappears all by itself.

Third could be to reset the configuration with the button in the preferences. Another possibility is to delete your config files or to move them in case you want to restore them.

and then my system crashed.

Do you have some more information what exactly crashed and why?

From the menu you see can you still switch to another workbench or does it also give you an invalid access? In case it works then try to create a new document and create a simple shape.

This looks like an older version of Windows 10. Mine says Version 2009.

It could be some DLL's get updated or something when you do the update. You should be getting automatic updates anyway for security purposes.

I thought I answered earlier...

Anyway, It's a GFX card issue. I need a new one but finding a decent one that won't break the bank is tough. Other rendering programs (blender, film editing) will crash my system quickly. I got a couple hours out of freecad.

I'm thinking just reinstall freecad and see where that takes me.
Which button in preferences?

On that note, I just started freecad again and get the above mentioned window.
I can load a workbench and the do File>New and get the workspace to load.

Which button in preferences?

At the bottom of the Preferences dialog is a "Reset" button.

reset didn't work. I'll see if uninstall/reinstall does anything.

Most probably not with 0.19. But you can try current 0.20.

Finally got around to fixing it. Uninstalled and reinstalled .19 and the error went away.
