To get a windows tool running in wine i've manually copied some registry entries across from a windows machine (the install program fails to run in wine on this particular machine), but it still fails to work.

Strangely, if i copy the registry entries (in system.reg) from another linux machine on which the installer does run in wine, then the program works fine.

The only difference seems to be the numbers after the entry in system.reg (e.g. [Software\\Wine\\Printing\\Spooler] 1128518253 - this is not the actual entry i'm using, but it does show the numbers).

What are these numbers, and could they really effect if a program works or not? (Note: the registry entry i'm copying seems to store an encoded version of the programs serial number).

Thanks in advance.

use regedit on windows,save the entry you want, but do it as a win98 .reg file. Then on wine just do
wine regedit filename.reg
