"start /wait" In INF's ?

[MaLi]

I have a problem with unregistering codecs when using INF's for uninstallation of a codec-pack.

If I remove the section where the files get deleted the codecs get unregistered just fine, so it seems as if the files get deleted before the unreg-process is finished.

Any clues ?
