I have the Age of Empires II Gold Edition which contains both Age of Empires II and the Conquerors discs. I have lost the Conquerors disc, so I am trying to play just Age of Empires II. However, on my laptop, if I run the Age of Empires II (not the expansion), it tells me "Please Insert the correct cd rom", despite having the correct CD in. This only occurs on my laptop. On my desktop, the game runs when using the same CD, so it's not a damaged CD.
I have tried uninstalling the game and installing without the Conquerors expansion in case it is trying to launch the expansion pack, but even then it gave the same error.
What could cause this error? Google says it's either a pirated disc (which it isn't) or a damaged disc (which it also isn't since it runs on the other computer). What other issues could cause it?
