Of the patches, I think you only need to install the latest patch and not 1.3. If I am wrong, please tell me. Patches should be cumlative and therefore 1.5 has 1.3 already included. And if you install BI, you just need patch 1.6 and none of the previous patches.

Therefore:
uninstall RTW, delete the activision folder, restart, install RTW, install patch 1.5, install EB 1.0

or

uninstall RTW, delete the activision folder, restart, install RTW, install Barbarian Invasion, install patch 1.6, install EB 1.0, install BI-EB launch exe.
