[solved] QCADCAM Crashes when starting up

Post by cmh31909 » Sun Nov 24, 2019 3:49 pm

I am trying to run the QCADCAM 64 bit version under Windows 10 x64. When I start the program, I get the splash screen showing it loading all of the plugins. When it gets to around 67% (Gerber stuff), the program crashes. I get the following exception:

Unhandled exception at 0x00007FFC5F51C706 (MxMGLV64.dll) in qcad.exe: 0xC0000005: Access violation reading location 0x0000000003304318. occurred

I also loaded the 64 bit version of just plain QCAD and it works with no problems.
I also tried loading the 32 bit version of QCADCAM and while it does not crash, it does not display any of the menus, toolbars, or toolboxes. it displays only a black screen with the title bar.

I would really like to use the QCADCAM package, but so far, I have not had much luck.
Does anyone have any suggestions on how to fix this problem?

Hi,

please avoid posting multiple identical post to the same topic - I deleted the other two ... :wink:

Which installation format did you use? msi or zip?

I apologize for the cross-posting, I did not know which forum was the appropriate one.

The only option that I could find to download was MSI.

Scroll down ...

But that doesn't fix your problem.

You will find the zip pretty much at the end of the download side - here is a direct link:
QCAD/CAM Demo
https://www.qcad.org/archives/qcad/qcad ... -win64.zip

I would recommend to start over. Please try the zip archive - it's working excellent on my Win10/64

To start over:
1. deinstall or delete on your system QCAD/CAM, you will find it below C:\Program Files\qcadcam-3.23.0-pro-win64,
2. delete the qcad3.ini - you will find it below C:\Users\username\AppData\Roaming\QCAD

3. download the QCAD/CAM version from the trial download side or directly via my postet download link,

4. unzip the version below C:\Program Files

5. To start qcad you will find in the qcadcam-3.23.0-pro-win64 folder a file called qcad.exe. A double-click on it will launch CAD/CAM in a demo mode.
To make the start the next time more convenient pin the qcad.exe to the Start menu or Task bar.

If you're done with testing the pro version and like to use it as a free community version then follow the instructions how to remove the demo add-ons:

viewtopic.php?f=76&t=4668#p17085

If you like to buy it here is a link to the Rippensoft online shop:

https://www.qcad.org/de/online-shop

I recommend to test the demo intensive - that is the reason why they offer a demo ... :wink: )
If you decide to buy .... keep an eye on bundle prices. I have seen up to 50% rebate or so .... :shock:

Please keep us postet.

Thanks Husky. However, the installer is very likely not the culprit.

This behaviour more likely indicates an OpenGL problem (OpenGL driver invalid, incompatible or not available).

Please remove the file "plugins/qcadgles3d.dll" and try again. Note that without that plugin, you will not have a 3D preview / simulation widget. To fix the problem, a working OpenGL driver would need to be installed. This can be daunting on Windows and is only really worth the trouble if you need the 3D simulation widget.

So it turns out it was a problem with the OpenGL and removing that dll did the trick.
Thanks to all those that replied!
