The following is from:

We ran into the same issue today in our clustered environment. The solution worked.


Today i got error while installing oracle on Windows server 2008 R2
When i clicked on "setup.exe" file, it throws an error as below:





Starting Oracle Universal Installer...

Checking installer requirements...

Checking operating system version: must be 5.0, 5.1, 5.2 or 6.0 . Actual 6.1

Failed <<<<

Exiting Oracle Universal Installer, log for this session can be found at C:\Prog
ram Files\Oracle\Inventory\logs\installActions2012-03-30_09-25-48AM.log

Please press Enter to exit...





After too much research i came to know that I need to modify the "oraparam.ini" file which
is placed with Oracle setup files.


I modify the Oraparam.ini file located here
"database\install\oraparam.ini"


Just add those words which are bold as below in the oraparam.ini file.

[Certified Versions]
# You can customise error message shown for failure, provide value for
CERTIFIED_VERSION_FAILURE_MESSAGE
Windows = 5.0,5.1,5.2,6.0,6.1



[Windows-6.1-required]
# Minimum display colours for OUI to run
MIN_DISPLAY_COLORS = 256
# Minimum CPU speed required for OUI
# CPU = 300


Save the oraparam.ini file & then run setup again. Now all goes fine & got the oracle installed.
