I am trying to install the 'Office 365 Desktop Setup Tool for Office 2010 and
2007'.

Due to bug #30753 I resorted to invoking the downloader directly

$ wine rundll32 dfshim.dll,ShOpenVerbApplication
http://g.microsoftonline.com/0BX00EN/436?%5C!/Office365DesktopSetup.applicat...

The installer starts up, but in the end fails, with the log file containing the
following error: Culture name 'sr-latn-cs' is not supported.

I have tried winxp and win7, and also installed dotnet35. Neither makes a
difference.

Note: this is not the setup for Office 365, but rather a compatibility layer
for Office 2010 and 2007, see
