# Install Oracle on Windows 64 Bit and migrate Oracle Windows from 32 bit to 64 bit

Installing Oracle 11g 64 bit on Windows Server 2008
When installing Oracle 11.1.0.7 on Windows Server 2008 64 bit, the installer gave a an error saying the Operating System ( OS ) was not supporting. In looking at the install log on c:\program files\oracle, I noticed the installer thinks the OS is windows vista.

To work around this error, I selected the check box for user verified and continued with the install.
