It was stated above:
Yes the version is same (1.6.10) on both machines.... exact error is " Could't load the module C:\Program Files\Wireshark\1.6.10\plugins\lip.dll: 'C:\Program Files\Wireshark\1.6.10\plugins\lip.dll': The specific module could not be found. "
Assuming a typical installation directory of C:\Program Files\Wireshark, on my system, and every other system I'm aware of, plugins are saved in C:\Program Files\Wireshark\plugins\<ver>\, and not in C:\Program Files\Wireshark\<ver>\plugins\.
In your case, shouldn't Wireshark be looking in C:\Program Files\Wireshark\plugins\1.6.10\?  Where exactly is your lip.dll file stored?  Are you sure it's stored in the correct location?  What does Wireshark's "Help -> About Wireshark -> Folders -> Global Plugins" indicate?
