To the best of my knowledge WC3 won't work on ME, 2000, and XP. A lack of DOS support.
You could try a bootdisk but only if your sound card has DOS support. What sound card do you have? Post your c:\autoexec.bat, C:\config.sys, and if you have one the c:\windows\dosstart.bat.
Better idea would be to buy a old 486DX or better PC at ebay for under $50.00 with DOS. Make sure it has a sound card, CD-ROM, 500 Meg HD and a least 16 megs of ram.
