Failover Detection - Strong name validation failed

[KenJ]

Downloaded latest failover detection utility on 2019-04-11 (exe modified on 2018-11-27 )

Gathered all log files together as outlined in the web instructions - https://techcommunity.microsoft.com/t5/SQL-Server/Failover-Detection-Utility-Availability-Group-Failover-Analysis/ba-p/386021

Followed the strong name workaround in the web instructions (update 11/27): sn -Vr "C:\ path \FailoverDetector" and sn -Vr "C:\ path \FailoverDetector\Microsoft.SqlServer.XEvent.Linq.dll"

Program exited with error: Validating log data instances includes: instance01 instance02

All data is ready for instance: instance01 folder. All data is ready for instance: instance02 folder.

Did you manage to solve this problem? I have the same issue

[fvanderhaegen]

I managed to get it working. I've you add following registrykeys, you disable strongname validation for all assemblies with this public key.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\StrongName\Verification\*,89845DCD8080CC91]
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\StrongName\Verification\*,89845DCD8080CC91]
