I cant install Blood Omen 2!!!Its say :
Please insert Orginal Blood Omen 2 disk!

P.S please help me!

It sounds like you're using the PC version of the game, so you might want to ask your question in the Blood Omen 2 PC forum.

The only threads I see about installation problems are located here and here, but neither of them seems to mention your problem.

I'm not sure what would cause it to give you that message, unless the game came with two discs (and you're using the wrong one) or the disc you're using is scratched and unreadable. If you purchased it from a store, take it back with the receipt and original game box and try to explain your situation. They might give you a refund, but they should at least replace your game with a working copy.

I can't install the game, when I click on the SETUP icon, and the INSTALL next, this shows http://zapodaj.net/e75cb0b9c791.jpg.html
