@Kinesis There are only two options: Install a compatible Qt version on the second computer Deploy all needed libraries along with your program. You may want to have a look at linuxdeployqt Regards

@sebs What I don't understand: you want an application with 3 threads, right? But why do you create new process?

@MikhailG thank u so much sir i will try.

No problem. Good luck with your project!

@Ratzz Thanks for the information regarding windowdeploy. I tried that initially but couldnt get it to work, although my .exe works on a different computer. I was just wondering if i could do the same with SQLite, I included the folder regarding sqlplatforms.

Hi and welcome to devnet, To add to @jsulm, did you build Qwt yourself ? If so, are you using the same setup as the people who provided the application ?
