The K2 Blackpearl Server service will not start

Nintex Community Menu Bar

The K2 Blackpearl Server service will not start, the error i get when manually starting the service is:
"The K2 blackpearl server service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs."

I have tried running a repair on the installation but that does nothing to help. In fact, during the repair i see these errors in the windows even logs.

This is setup is one k2 server and one sql server both on 2012 r2, the K2 version is 4.7.

Any help would be appreciated.

I have been comparing prod and qa to check for differences and the only thing that i can see is that on the prod k2 app server the SQL Server (SQLExpress) service is running and it is not on the QA server. Does the K2 BlackPearl Server service rely on that service to running?

Please try run K2 Server console using K2service account (the account that K2 use to access K2 DB). and check what is the console output.

This is the output from the console:

;K2 HostServer Console Mode

Please check on this.

Hi YUDI2,
I looked in the GAC and saw two entries for SourceCode.HostClient.API,

The Global Assembly Cache contains the following assemblies:
SourceCode.HostClientAPI, Version=4.0.0.0, Culture=neutral, PublicKeyToken=16a2c5aaaa1b130d, processorArchitecture=AMD64
SourceCode.HostClientAPI, Version=4.0.0.0, Culture=neutral, PublicKeyToken=16a2c5aaaa1b130d, processorArchitecture=x86

The x86 dll version matches what is in the HostServer/Bin folder and AMD64 is older. does that AMD64 belong in there?

What is your processor architecture ? it shouldn’t be duplicated, you may try to comment out the AMD64 setting and try start up K2 Server console.

K2 Server console is complaining about public token 16a2c5aaaa1b130d the same as your finding

i cant remove any of those dlls from the assembly, it says they are required.

I finally got it!!!!!

It was not only the SourceCode.HostClientAPI.dll but also SourceCode.HostServerInterfaces.dll. That one was still on the older version. Once i updated GAC with the correct DLLs the K2 Server service started.

Thanks for pointing me in the right direction YUDI2!
