When installing the client to a Windows XP virtual machine (as you do) I noted the following requirements: 1. Install Windows XP 32-bit as per normal 2. Install DotNet40 3. Install the client package from the download page 4. Install the latest UO:R Razor Software Notes Be sure to use the newest Razor version. If you get some error about bad application configuration just delete the file "Razor.exe.config". UOAM works fine as well. VirtualBox Notes JMap seems to hang for minutes or even crash when running in Seemless Mode (HOST+L) Viewport Scaling works great! I never did get audio stabilized. The VM audio is stable using the PulseAudio and ALSA backends with ICH AC97 emulation, however the game audio only works for a few minutes before crapping out. Screenshot
