can't install Warnings at Waverly Academy

I am using Windows 7. It says the file WAC19.cab is missing or corrupt. I have two discs. This message appears after it asks for disc 2. What do I do now?

There's some information about that kind of message here. The article also shows a workaround to try.

It worked! Thank you Marian.

I am very glad to hear that. Enjoy the game.
