.exe file don't work correct on different PC
-
I am working on an application, that takes frames from 4 webcams (i named the webcams 1,2,3,4). It can run maximum any 2 webcams simultaneously (1 and 2; 1 and 3; 1 and 4; 2 and 3 ...). I can select from an USB custom device, which webcam/s are running.
The problem is that .exe file that was created in release directory, works correctly on my PC, but when i move my application on other PC, when i select webcams 3 and 4, it starts just webcam 3. Or when i only select webcam 4, it also starts webcam 3.
I used Qt creator 2.4.1 (based on Qt4.7.4 32bit), and OpenCV2.4.2., on 32bit Windows7. I am trying to run my application on the other computer with Windows7 32bit.
For my .exe to work, i had to copy some .dll files from OpenCv installation, in the same directory with the .exe file. So, i think that i have to recompile OpenCv on the other computer too, so my application can run correctly but i'm not sure about this. Might this work ?

Don't think you need to recompile openCV. If that is the problem, the program woudn't run anyway and give a "couldn't find dll" stuff errors.
As mrdebug says it is probably caused by Win7 and how it handles webcams. Maybe install Qt on a Win7 and start testing it there.
