Not finding the game

[Peterisgb]

When i run the game is doesn't find the game, I have uninstalled and reinstalled openRCT2, I am running windows 10 i need to set this program as administrator for it to work.Now here comes the problem, normally i would right click either run as or properties it and click the box, however this does not show up and i cannot seem to find where it has installed itself on the C drive to manually run as without the shortcut.so a directory where it installs would be very helpful, or any other way would be welcome too. thanks.
