Re: safe way to upgrade KMDF from V1.0 to V1.1


I changed it to KMDFV1.5 cointaller. Everything seems the same as
before. :-(
Any more tips?
--
I have the similar problem with my drivers when I upgraded them from
KMDF 1.0 to 1.1.
I used regmon utility from sysinternals to log KMDF co-installer
accesses to the registry, and I manually restore those that were
absent, in order to correctly install and start new 1.1 driver.
It seems that KMDF co-installer expects some entries in the registry to
pre-exist and failed when it does not find them. If this is true, it
may be useful to change it's algorithm and create those entries during
it's work if, for some reason, they are absent. Or, at least, clearly
describe this situation to the user in some way.
