I can't install any program through playonlinux, the POL_WINE error always occurs, saying that the version is no longer available.
could someone tell me what happens?
Make sure to use the Wine Manager (under Tools) to download a version of Wine before installing any games.
Normally when you install PlayOnLinux you need to have Wine-Stable installed first, but its not required because you can just install your own version and use it.
Does that help?
