The winecfg of my system (which is 1.7.24) opens. The /mnt/data/.PlayOnLinux/wineprefix/Wine32_ver1.62 directory is the directory where I store the wine 1.6.2 version. In my opinion winecfg 1.6.2 should be opened with this command.
Is that something wrong in my system so that whatever prefix I choose, I run the system version of wine? Or running winecfg command is not a good way of checking the wine version? Or it is the good way but I do it wrong way?
