Hi Eric,

I'm not sure I follow you are maybe you are misunderstanding me.  There 
is no issue.  Luis helped me understand how to determine the gem 
environment and explained the path.

When I make a backup of any ruby installation (I keep 3 currently), I 
keep them in the root directory and just append a date or backup to 
them.  There's nothing wrong with doing this.

Whichever Ruby version I want to use remains in the same location and 
same directory structure..

Example:

I have currently:

C:\Ruby (primary install and version I am using)
C:\Ruby_1.8.7 (backup version of 1.8.7 install)
C:\Ruby.backup (primary backup of the current version I am using)

If I decide to use Ruby 1.8.7, I rename my primary install folder 
Ruby.OLD or whatever folder name I decide to use.  Nothing has been 
tampered with here.  No moving of locations or inner movings of anything 
within the base directory.

I then rename Ruby_1.8.7 back to Ruby and am able to use Ruby 187 as my 
primary install.

All 3 installations work 100% with no issues.  I have no problems doing 
it this way.  My path is set to C:\Ruby\bin so C:\Ruby is my primary 
installation folder.

So, again, maybe I'm misunderstanding what you are saying here.  Again, 
I have no issues..
