Microsoft Fonts

That script is the old one. You use POL_Install_corefonts instead. We keep it only for some old script outdated.

POL_Instal_corefonts also have the same problems (not storing the .exe files in som sort of a cache and downloading twice in a row).

It's not that. The script store downloaded file, install as generic (for all wineprefix) and mark them as installed. But the current version of the script crash and nerver install font. I already submited a patch but I need to know if the URL is good for Tinou. Because it's a non know source (at least for me) but it come from winetrick source code.

Btw I patch the POL/POM corefonts function so now it should work fine

POL_Install_corefonts definitely can't install fonts due to broken links to MS font EXE files. Same situation during last 3 years happen very often on ttf-mscorefonts or similar MS font package installation from various Linux distro repositories. Seems mirrors where fonts are supposedly hosted, dwindled or got overloaded with time. However if MS fonts are already installed in system from repositories or MS font packages earlier, software launched under Wine inside PlayOnLinux bundles, see and use installed MS fonts from system just fine. Because of that I would be glad if PlayOnLinux developers would update POL_Install_corefonts script and make it optional. On launch it should ask are user want to download MS fonts and gracefully exit on negative response thus allowing the rest of software installation continue to finish without fuss.
