Mpclaim.exe is not running in windows server 2008 SP2 x_64

I was added Multipath IO Features in windows server 2008 SP2 x_64 using "Add Features" wizard in server manager.

After that I added my storage and devices in MPIO devices.

Then I ran "mpclaim.exe -s -d" command but it was failed to execute. It always gives the following message:

"Install MPIO OC then ensures msdsm claims pass in devices"

I was also applied KB 2522766, as per suggested in Microsoft site, but it is still showing the same message.

Then I have also tried following commands :

“ocsetup MultipathIo /norestart” and then run “ mpclaim –r –i –a “” ”

but it fails to execute all mpclaim command options and give the same message.

I was tried the same settings in "windows server 2008 r2 x_64"  they are running properly here.

Is there any issue with OS or anything else????

Please help me.

Any help is highly appreciated .

Thanks & Regards,
