I have an ASUS P5P800 MOBO, (latest BIOS) wP4-3.0 and 2GB RAM and I have been trying to install Windows Vista Ultimate upgrade but it fails at the end. The reason shown is SiWinApp.Sys with an Error Code of 0x00000098. It appears that it cannot find this file. It shows the black screen and will only allow you to "Enter" or basically rollback the install. If you press Enter, it repeats the cycle. The rollback works great, but I'd like to get a good install on this.
I've updated all drivers available from ASUS to the latest and I cannot find any good information on this error. When running the Windows Vista Upgrade Advisor it appears that the upgrade should work. Any suggestions would be greatly appreciated. Thanks.
