MTM Scripts are not Working in UFT 11.5

Hi Floks,
This is vijay, we have directly migrated from QTP 11.0 to UFT 11.5 Version. Till 11.0 Version MTM(Multi Test Manager) is working but when we migrated to UFT 11.5
it is throwing an error saying that unable to run the scripts. my question here is do MTM is supported by UFT 11.5 , yes means do we need to install
any patch for this. Waiting for your reply. you can mail me on "nallapusalavijay@gmail.com"

Thanks&Regards
Vijay.Reddy
