The Windows Vista bloatware is currently in beta. I have tried BRU on build 5384 and it does not run. I do not know the reason why, all I know is that it does not even get into the main section of code.
At present the only way I can run Vista is to install it in Virtual PC 2004, as Vista does not recognise my RAID hardware. Unfortunately Vista is very slow in VPC, despite my own PC being a P4 2.8 with 2GB RAM. As such, it's not practical to debug.
When Vista is released, I am intending to replace my hardware. This will allow me to test BRU properly.
Therefore, until Vista is released, I cannot offer any support to running BRU on the Vista platform. Indeed, even when Vista is released, I may still be unable to support it if I do not upgrade my own hardware.
