[wix-users] Difxapp and minor upgrades

It seems like this confirms that the issue is at the INF/Class Installer level and not related to MSI, so I would focus on understanding the driver rank decisions which will be indicated in a verbose log.

For verbose logging of setupapi is the LogMask defined?  (0xFFFFFFFF) with LogLevel (0x00007070)

https://msdn.microsoft.com/en-us/library/windows/hardware/ff550845(v=vs.85).aspx

I usually find details about the rank decision in the log when these verbose settings are used, and then using the link sent previously to sort out the meaning of the rank scores.

Using DifxApp for filter drivers imposes some additional requirements detailed here:
https://msdn.microsoft.com/en-us/library/windows/hardware/ff543646(v=vs.85).aspx

Most of my drivers are PnP Printer drivers, but a I also had a filter driver (which is a non-pnp driver) at one time.  Generally ChkINF is helpful for finding major problems generic to any type of INF but it generally was not helpful in identifying issues specific to a particular class of INF files.  In fact when I last used it, ChkINF will throw errors on entries which are required by the Printer Class.  If those entries are not there the INF does not work, but ChkINF says it is OK, so I don't have confidence in the results of ChkInf for specialized classes.  (I have not used the most recent WDK and ChkINF, so your mileage may be different.)

Hi,

Setupapi.dev.log does not reveal any issues. I am using difxapp exension. I already tested manual installation and upgrade.
The behaviour was the same, i.e. the driver was not updated properly.

I have also checked (chkinf and manual review) the INF-file for errors, but saw none. I think a minor upgrade should be able to upgrade drivers as well, so my assumption is that there might be something wrong in the INF-file. Any ideas what specific issues in the INF file might cause this?

Regards,

//Hannu
