Windows 10
QCAD 3.20.1 pro

Unable to save file, so reinstalled using MSI. (uninstall, reboot, reinstall).

If you try to save a document, you get a generic dialogue that indicates that QCAD has crashed, and a button to close the program.
You don't actually have to try to save it, you just need to select save from the menu and wait for it to fail.

The program was originally installed using the trial, then upgraded to Pro, and that is when the problem started.
The program was then uninstalled, and reinstalled. We tried this twice.

Is there any file that needs to be manually deleted?
I've done some searching in the forums, and I can see older issues with save, but nothing recent.
I looked at the FAQ, but there was nothing pertaining to Windows 10 (unless I just missed it).

Any assistance would be greatly appreciated.

Thanks!

Hi jedixo - welcome to the QCAD Forum.

Sounds like something went wrong ....

Lets start from scratch to make it as easy as possible.

1. Delete "Manually" all QCAD directory's (?). You can use the Win10 File Explorer. Look for QCAD installation below C:\Program Files.
I assume it's called C:\Program Files\qcad-3.20.1-pro-win64
2. Then rename (for Backup reason) the qcad3.ini below C:\Users\XXX\AppData\Roaming\QCAD
3. Make sure you have the correct msi file (32 or 64 bit System) and install QCAD again.

Now test it again and please keep us posted how it works ...

Oops, didn't see your response before I pasted in deets. I'll give it a shot

Hey Andrew, this seems to have worked! Thanks.

Andrew?
However, glad to hear it works!

it's happening again. I don't really want to reinstall again. Any other suggestions?

0xc0000005 is an access violation, which could have multiple root causes (null pointer, etc., but I suspect Andrew would never leave a null pointer hanging ). I've seen where resetting the pagefile has fixed similar issues when physical memory was low, apps were swapping a lot and the pagefile became corrupted.

Does it fail on the same DLL every time (ntdll.dll)? Do any other apps fail likewise?

Or... Is your anti-virus solution possibly interfering? A Windows update?

Even less likely, but... When you reinstalled last time, did you search the registry for any QCAD entries and delete them first? I'm not 100% certain whether QCAD even writes to the registry (I'm on Linux and don't have my Windows laptop up now), but if so they might likely be under HKEY_LOCAL_MACHINE/Software and / or HKEY_CURRENT_USER/Software, I suspect.
