[solved] QCAD doesn't run after upgrade

Post by Pegasus » Wed Jan 11, 2023 3:53 pm

Win 8.1 Pro, updating from QCAD 3.15.2 to 3.27.8

QCAD (trial) was installed and working on my Win 8.1 Pro PC. Had not used for a long while but I wanted to update an old file that I had drawn as a plan for my workshop, all OK, I could edit it.

I am considering purchasing along with CAM module since I will be doing some CNC work, so I decided to upgrade to see the latest features.

I downloaded and installed 3.27.8 and installed, seemed to go OK but when I try to run from an icon on my desktop I just get a small rotating blue circle for a couple of seconds and the app does not open.

Having searched and seen another forum article (though relating to Linux) I then tried to run directly by finding the install folder and double clicking QCAD.exe, but again the app did not open.

Any ideas how to fix this?

Regards,
Graham

Please double-check if you have installed the correct version (32bit or 64bit):

If you have installed the correct package, you might have to reset your configuration:

Thank you Andrew for your impressively prompt reply.

Both my Windows 8.1 Pro and the old QCAD version I had and the new version are 64 bit.

I have followed the link you specified and that you linked and renamed the QCAD3.ini and library_3_0_0_9.db files but I still have the same problem, I note that new versions of the two files have not appeared.

I looked in the Event Log and found the following which I am unable to interpret, perhaps it means something to you?

Faulting application name: qcad.exe, version: 3.27.8.0, time stamp: 0x633e8c98

Thanks. No, that doesn't help much. It looks like it doesn't get far. Can you try the 32bit package instead?

Thanks, but before I try that perhaps this from the app crash report.wer file might help?

That error code C0000005 is memory access violation error caused by a buffer overrun?

If this doesn't mean anything to you either then I will uninstall everything relating to QCAD and reinstall.

I went ahead and uninstalled the new version 3.27.8 (using Windows Add or Remove Programs) and as the old version 3.15.2 was also listed there I uninstalled that too, then manually removed remnants that I could see in the file system, and reinstalled the 64 bit version using my original download.

It is now working OK.
