Even though you log in as an Admin with the account you have, it has limits. This is something Vista did to protect you from yourself. In other words, you don't have full administrator priveleges.
You can log on as a full admin a few different ways. One way is to simply unhide the true admin logon in a cmd.
click the start menu.
In the bottom search bar type cmd (don't hit enter)
cmd will show in the list on top .. right click on it and click to run as administrator
the command panel will open
type this command exactly as it appears here.. or just copy and paste it in the cmd panel
net user administrator /active:yes
hit enter and it should tell you it completed successfully.
close the cmd panel and log off of windows.
When you log back on you should have a new Admin log on.
Log on as admin and try to run your program that way.
It might be a good idea to keep your regular user logon and use that for normal functioning.
You might also want to create a password for the admin logon and only use that for technical purposes.
