Windows System State Analyzer 3.0 failing to compare file system snapshots

I have an issue with the Windows System State Analyzer 3.0.

The tool takes snapshots of the status of file systems, drivers, registry and services statuses, but when I try to compare those, it fails the file system comparison.

All the other types of comparisons work, but the file system one fails every single time.

This is a typical stack trace while attempting to compare file system (it fails also if the snapshots files are stored locally):

C:\Program Files\Microsoft Logo\Software Certification Toolkit\Windows System State Analyzer>SAnalyzer.exe compare "\\ServerName\c$\Users\Public\Documents\Pre install.bin" "\\ServerName\c$\Users\Public\Documents\Post install.bin" /fa CompareResult.html

Searching on the web, Markus' last post in this thread is probably describing the root of this issue:

I have tried to ask the Microsoft relevant team if they had plans to solve this issue, and release a new updated version of the tool, but their mailbox ([email protected]) doesn't work anymore.

Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain microsoft.com by microsoft-com.mail.protection.outlook.com. [23.103.156.42].

The comparison tool works for the registry, the services, the drivers, but not for the file system.

Both from the GUI and the user interface.

I tried the comparison on a number of OS, e.g. from Windows 2012 R2 to Windows 7, and I have also tried the Microsoft XP compatibility mode, to not avail.

I have used this tool extensively in the past, to certify applications on Windows Server 2008 R2, and it used to work without a glitch.

Any suggested work around? Alternative suppliers?
