winecheck errors

[Dan Sawyer]

Well all,

Edgar's winecheck caused me to try it agein and sure enough there is an 
error:

028. Checking availability of winedefault.reg entries...    CRITICAL 
(entry "SHAREDMEMLOCATION" not found in system.reg registry file).
- ADVICE: file winedefault.reg, the most basic wine registry 
environment, doesn't seem to have been applied using regedit.

What does this mean? (I have no idea what system.reg is, where it is, 
where it came from, etc.) 

How can it be fixed??
