Asserting (in a very vague way) that it seems to be 'internal errors' ~ is likely not helpful, nor useful to anyone who might be able to help identify your problem. wiki.wineHQ.org (the wiki pages) has excellent resources on how to collect information. Have a look through. The FAQ is very useful and covers a lot of stuff; http://wiki.winehq.org/FAQ > how do I downgrade back to wine 1.5.1 on ubuntu ? there seems to be no wine-package with 1.5.1 for ubuntu ... how can I solve this ? Well, with a bit of googling, it would sem 1.5.1 isn't packaged for ubuntu because of a bug where wine app icons weren't showing up in the Dash, as cited here; (scroll down to wine 1.5.1) http://www.ubuntuupdates.org/package/wine/precise/main/base/wine So you could use this version, just don't expect the icons to work properly with Unity's dash (if you use unity). You also have the option of compiling wine from source; http://www.winehq.org/docs/wineusr-guide/installing-wine-source you can grab any version of wine (source code) that you like from here; http://sourceforge.net/projects/wine/files/Source/ just scroll down the page to find the whatever version you are looking for. so those are some options, anyway. cheerz
