This is because your application is signed with a different debug key on each of the computers.

You can, however, overwrite the key from computer A with computer B's. Then they'll be signed with the same key. I don't remember where this key resides, however.

According to this post: https://stackoverflow.com/a/9398619/2155492

Open Eclipse Preferences, then navigate to Android > Build. There you'll see a field that tells the location of your debug keystore.

To solve the problem, simply uninstall the current application from the test device, and try launching again. Do not do this if you would like to persist application preferences and other data on the device.
