Windows 7 & batch files copy access denied

Hi

We have a batch file which needs to copy an exe file to the local c:\ drive and then run. The only problem being is that we get 'access denied'.

If i run this locally with cmd 'run as administrator' it works but I need to push this out to over 100 users and for it to work each time a user logs on and off.

So the question is how do I run this batch file which will have access to copy the file to the c:\ and then execute the exe, even if the user is not a local admin?

Thanks
