[SD-User] Installing new version 12.05?

[David Gould]

I have V12.04 installed in directory SD1204 and have shortcuts on my 
desktop for SD and SDCHECK. pointing to the SD1204 directory.

How should I install V12.05, I would prefer NOT to remove all of 
V12.04 in case I need to go back to it?

If I install into directory SD1205 will I get TWO NEW shortcuts on my 
desktop? or will there be confusion with the existing shortcuts?

I can't find any instructions in the manual or the website..
