Hi, Felix.
Even though UWS reports that the OS is incompatible, it does not check the OS per se. It checks the presence of the http.sys - a kernel-level driver introduced with XP SP2, which UWS relies upon.
You may not be able to run UWS on WINE because, according to
WINE Wikipedia article,
"Although Wine implements some aspects of the Windows kernel, it is not possible to use native Windows drivers with it, due to Wine's underlying architecture. This prevents certain applications and games from working, such as some copy-protected applications and games."
Since http.sys is a kernel.level driver, we suspect it's one of the pieces that WINESERVER does not implement, thus making UWS incompatible with WINE. The most viable alternative is to run UWS in a virtual machine.
