[Wine] How to know which env vars a software wants

[xekhz]

Hello ppl.
Im trying to install an aplication and for some reason ir says.
"Cannot get enviorment variables"
I spoke with the developer and he told me that it is because i dont have microsoft DAC installed. 
I installed it and the problem persists.
I need to know how to see which ENV vars the software wants in order to create them.

It is not a wine problem because I get the same error instaling in a XP Home edition

Thanks for the help in advance
