I am not sure where the global winver is set but I am sure its still
in the registry so you can change it with a registry key as Julliard
said. For just running per-application all you need to do is set it as
HKCU\Software\Wine\AppDefaults\foo.exe\Version which is a string
resource, again this can be done via a reg file that regedit can
import. Thats even less complicated then then inf route I suggested.

Do you mean you have a situation like a broken application AND
installer that only works under win98 but the default version is
win2000? Maybe you only want that installer to run in win98 mode but
the rest of wine to run in win2000 mode? Wine used to have the -winver
option I think and CrossOver has this setting but I can't see anyway
to set the windows version on the command line for a buggy installer.
The solution (which I also think kind of sucks) would be to do
something like script

wine regedit add-setup.exe-version.reg
wine setup.exe
wine regedit remove-setup.exe-version.reg
wine regedit add-foo.exe-version.reg
wine foo.exe

Of course steps 3 and 4 could be combined in one registry file and 1
and 3 would not even be needed if you could set the version on the
command line but we don't seem to support that anymore for quite a
long time. I think the solution to have multiple appdefaults with
programs having generic names like setup.exe and install.exe is to
enhance the support in wine and winecfg application/dlloverrides to
use md5sum/sha hashes. I don't know how julliard really feels about
this but this is similar to what was discussed with having a custom
Wine shim engine for application compatibly. If you were going to
change some code and he approves I think this is the route to go.....

So say rather than having

HKCU\Software\Wine\AppDefaults\setup.exe\Version win98

you would have something like

HKCU\Software\Wine\AppDefaults\b83fd2e8b34ba6b6f59e9f9cfbe129d9\Version win98
HKCU\Software\Wine\AppDefaults\b83fd2e8b34ba6b6f59e9f9cfbe129d9\filename
setup.exe

HKCU\Software\Wine\AppDefaults\912672566150fd7663fba3a927f79fca\Version win2000
HKCU\Software\Wine\AppDefaults\912672566150fd7663fba3a927f79fca\filename
setup.exe

This way two installers both named setup.exe can have their own
windows version and dlloverrides set.

Thanks
