I have opencv 2.4.9 on my windows 7 system. I need to build opencv 3.0 for some of its functions. Can I have two versions of opencv installed simultaneously? Or do I uninstall the older version before building opencv3?

Thanks, SY

You can certainly install more than one version of OpenCV simultaneously. Just be careful in pointing your directory settings and additional inputs in Visual Studio (assuming that is what you are using). Also, make sure that the PATH variable for DLLs is set appropriately.

Also make sure that your 3.0 installation is before your 2.4.9 installation in your path variable. When looking for the DLL's you will otherwise get conflicts in addressing the wrong dll files.

If you are using Visual Studio on your Win7 machine, I recommend using property sheets for your different versions
