Hi,
Download latest version OPENPS FOR MS PROJECT 4.0 SP04 from SAP marketplace. But it will support up to Windows 7 only, not for windows 8.
I cannot see the OpenPS_neither in my program list, nor in MSP screen.
It will not available in My Programs. OpenPS tab will be in MSP after successful installation.
Also go thru the below link for config details:
