These are the instructions for installation I keep seeing. I dont understand # 2. What is 1.0, and how do I get it? I have v1.5 for sure, so how to I install a clean version of 1.0 if I have 1.5? Or do I just install Total Realism 6 Gold?

1. Uninstall all traces of Rome: Total War from your PC.
2. Install a clean version of Rome Total War 1.0 from your CD-ROM.
3. Install the official Rome Total War 1.2 Update Patch
4. Install Rome Total Realism 6 Gold into your Rome Total War directory.
5. [Optional] Install the Music Addon (recommended)
6. Play!
