Package Deployment Not Working

Hello,

I am trying to test deploy a package but for Windows 8.1 machines, this doesnt seems to work and gives below in Execmgr.log. Have tried few Windows 8.1 machines but its same on all.

Remains stalled at the below status and doesn't proceed at all. There are no errors though in any of the log files.

The same package works flawlessly for Windows 7 machines.

Have tried EXE, MSI files and even created a new package from scratch but its the same for Windows 8.1 machines.

Any suggestions ?
