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

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

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.
