Error during installing Adobe LifeCycle Designer

Hi all,

I am trying to install Adobe LifeCycle Designer 8.1 , already downloaded all files from service marketplace.

But while running set up,getting below error message:

The SAP Front-End Installer executable is unable to process the XML files.Restart the uninstallation  with the

NwSapSetup executable installed  on the workstation.

Do anyone knows about this error message.

Thanks in advance.
