Below are troubleshooting steps for the original WarCraft and WarCraft II video games released by Blizzard.

WarCraft

Mouse is not working correctly

Verify the latest mouse driver is installed on the computer.

Getting memory errors

Ensure you are not running any TSRs if you’re running WarCraft in Windows 95 or Windows 98. If you continue to run into problems in the game, you may need to make a boot disk.

WarCraft II

Difficulty with your sound card

Verify the correct drivers are loading and ensure you have the correct specifications. Also, see the included readme.txt file that includes many of the most common problems and how to resolve them.

When attempting to run get “ISO-9660” error

An ISO-9660 error is usually caused by CD-ROM / CD-ROM driver; ensure you are running version 2.20 of Mscdex.exe by going to DOS and typing mscdex. If you’re running 2.20 or later and it is still giving you the ISO-9660 error, your CD-ROM may be conflicting because it may be the older High-Sierra Standard.

I am not able to end level five

More than likely you have not killed all the units; therefore, it is not ending. Press the Tab key to get rid of fog on the mini map and look for the gray character.
