You will have to install "Drizzle".
Then by the Drizzle You will install "Offline KI".
After that it just a matter of copying files to proper directories OF URU:CC:
- PRP and AGe files go to "dat"
- py files go to Python
- sound goes to "sfx"
New ages will be accesible though Nexus in "restoration links" (usually at the and of the list as "AGENAME (unknow age)").
If You got working version of an Age You can post it here, and it will be aded to UAM (probably by Old Wolle) to others enjoy.
