Install ie7 on wine on a default kubuntu 12.04

I get a error that 64 bit is not supported after doing a 
Code:
winetricks ie7



then i found some old bug and there they say all you have to do it type 
Code:
export WINEARCH=win32

 into a console b4 the .wine folder is created.

well i did delite my .wine folder typed 
Code:
export WINEARCH=win32

 into my console and stated wine config(which makes wine create the .wine folder)

but inside the folder still is a program files x86 and a normal program files, seems that did not work

winetricks ie7 gives me

Code:
winetricks ie7
------------------------------------------------------
wine cmd.exe /c echo '%ProgramFiles%' returned empty string
------------------------------------------------------



this now.

anything i can do? i am not understanding this WINEARCH. whats the defaut wine in ubuntu 64? is it a 64 bit wine? or 32 bit wine? or is it both and i can really switch ?

or just tell me how to get 32bit wine running with ie7 on (k)ubuntu 12.04[/list]
