I have brazil installed in max 8 on Vista. It worked fine, other than I had to run the batch file to start it once in awhile. Now Vista totally removed sfmgr.exe, and it won't reinstall, the batch file installer just crashes with a windows error saying that sfmgr.exe has stopped working, then windows closes it. It won't install or anything now. As far as I can tell, it's all unblocked from all AV and spyware apps.
