Version 4.3.31 installs and runs with msxml 3.0 and .Net framework 4.5 installed. Windows version set to Windows 7.
Could view some RAW files (incl. which AF points have been used, which was the main reason I tried it), do some adjustments and export them as JPEG.
Is a little slow to start and the GUI feels a little bit sluggish. But I have not compared that to how it runs natively on windows.
When also native GDI+ is installed, it starts faster (and also is perhaps a slight bit more responsive, but I'm not completely sure here). The downside is that in about 2 of 3 times the program is started, nothing seems to happen and it has to be killed by hand. So without native GDI+ it starts faster on average if you take the "try, kill, retry" into account.
