Hi , We are trying to install oracle apps 11.5.10 on windows server. After completing all pre-req things to install apps on windows i started rapizwiz.exe to start apps instllation.rapidwis has checked pre-req things like space requirement and other things. and when i click on install. apps screen disappeared w/o any error. apps instllation log file is also not showing any error. Any idea what could be the reason ?. If any one knows the note/Docs for apps install(11.5.10) on windows then plz let me know Regards Sanjay
