Thanks for reply. That Application is VMware-viclient 4.0 which I wanted to install on top of Windows7. But I fixed it like below :
*** I realized that VMware client 4.1 is support Windows7. And installed 4.1 version first. Then I tried to use but it complaining that I have to use vmware client version that installed on my system so it is 4.0. So I installed vmware client 4.0 on top of 4.1. then I see it is working.
Probably 4.1 is installed some missing dll. files .
