Using DIFxApp for Net Client install

I've been trying to use the DIFxAPP code to install our NFS Client Device
driver and have been running into problems. The DIFxAPP code requires a
WHQL digital signature.for use with Windows 2000 and XP. Since we have no
hardware we cannot take advantage of that program. An Authenticode
signature can be used for Windows Server 2003, but apparently not for Win2k
and XP (According to the Authenticode doc anyway). Has anyone else run into
this problem? Any workarounds?

Does anyone know why a WHQL digital signature is a requirement? Any idea if
this requirement might be relaxed in the future?


The error that cat get past is 0x800B0100L which is "No signature was
present in the subject."

I have supplied an Authenticode signiture, so I'm guessing that it wants a
WHQL digital signature, correct?

WHQL digitial signature is *not* a requirement with the DIFx tools.
Authenticode should work fine too. The samples that shipped with the DIFx
tools are actually signed with authenticode certificates, and not WHQL
certificates.

Not sure why you are seeing the error with your authenticode certificate.

Thanks for the reply. I did get it to install (somehow, still not sure what
I did different). My app seems to work just fine But I get the following
when trying to uninstall:

DIFXAPP: Uninstalling driver store
netwrq_557f28571680e580fa01bdffbd525f88a3433373.

DIFXAPP: ERROR 0x4A020 encountered while uninstalling the inf
'F:\WINDOWS\INF\oem22.inf'.
DIFXAPP: ERROR encountered while uninstalling driver store
netwrq_557f28571680e580fa01bdffbd525f88a3433373.

An then the uninstall rolls back.

Any idea what error 0x4A020 might be? The user doing the uninstall is the
same one that did the install and is an Admin.
