MSI trouble with ALLUSERPROFILE

[Vitaly Lipatov]

I get err with %ALLUSERPROFILE during install program:

trace:msi:MSI_FormatRecordW (L"[%ALLUSERSPROFILE]")
trace:msi:deformat_string_internal Starting with L"[%ALLUSERSPROFILE]"
trace:msi:find_next_outermost_key Found Key L"%ALLUSERSPROFILE"
trace:msi:deformat_string_internal Current (null) .. L"%ALLUSERSPROFILE"
err:msi:deformat_environment Unknown environment variable
trace:msi:deformat_string_internal after everything (null)

Where I will set this env variable? (I know I can do it in shell, but what is 
the right way?)
