Can't get installed qcad pro 64 bit to run on linux mint (cinnamon 22.3)

Hi, I just bought qcad pro 64 bit (recommended) and am trying to install it on a linux mint (22.3 cinnamon) desktop and linux mint (22.3 cinnamon) laptop. I got it going on the laptop but after 4 or 5 attempts at uninstalling and reinstalling I cannot get it to run on the desktop. It downloads, I change the permissions to make it executable but when I instruct it to run on terminal or just run it goes through a short routine creates an icon on the desktop and then stops and wont do anything else. Any suggestions would be greatly appreciated.

Welcome to the forums !

which release package are you using ?

Thank you for your reply. I’m not sure what you mean by ā€œrelease packageā€ but the button I pushed on the qcad download page said: qcad-3.32.6-pro-linux-qt5.14-x86_64.run Version 3.32.6 (recommended)

Apart from the version number that’s exactly the package that I’ve always used, and without an problems. I also use Linux Mint with Cinnamon 22.3.
When you say you’ve changed the permissions to Execute, do you mean the QCAD file in your home/opt/qcad-3.32.6-pro-linux-qt5.14-x86_64/ folder, that is what I have always used to start Qcad, but via a desktop launcher, but double clicking that file has always worked as well.
If the above is correct then I’d try deleting the configuration file to allow Qcad to rebuild it.

Actually reading your first post again, I think it’s the install file you’re having trouble running, is that correct?. If so then then with the Execute permission set on the file you downloaded, double clicking it should display a dialogue with various options, you should select ā€˜Run in Terminal’, that should install Qcad to the home/opt/qcad-3.32.6-pro-linux-qt5.14-x86_64/ folder.

Thanks petevick, yes, I used the double click method. I think the problem is that I had the free version loaded first and there is some scrap of code floating around somewhere that I haven’t deleted. I saw the process work the way it is supposed to on my laptop. As I recall after I hit ā€˜run in terminal’ it went thru a bit of a process in terminal and then loaded the program. With my desktop when I press ā€˜run in terminal’ it just prints out a dozen lines of words and then stops. I just don’t know enough about all the file systems to really scrub out all the old files so that I can try a clean install. I ran the uninstall program and deleted the opt file but that’s all that I can figure out to do.

Qcad is totally self contained within one folder, it will probably be in the home/opt folder, the folder name should be similar to what I mentioned above. Just delete that folder, or even the opt folder as long as there are no other applications in it. You should also delete the configuration file which is in the .config/QCAD folder and is named qcad3.conf. Once you’ve done that try installing the run file you downloaded again.

Thanks I’ll give it a go

Yeah! It worked. Thanks so much for your help.
