I use Vista but, I do not need to open with Admin. I can just click and start. Someone said to tell you to right click the LC icon and go to Properties and look in there for a way to remove needing to use Admin.I'm not sure being I do now have W7 but, worth a try.
Might also do a goggle search of how to open without using Administrator. Some PC place might have a post how to.
Good Luck
