Hi All,

I had a client who experienced the following errors on there server. These error where noticed because the Client Event Notifications were not being sent.

Solution:

The problem occurs when you install K2 on a drive that is not where the OS is and it uses the path eINSTALLDIR] instead of the full path. Please follow the ininformation below. 

The most likely cause is the error that is reported as "Could not load file or assembly 'sINSTALLDIR]Host ServerBinSourceCode.EventBus.EventAssemblies.dll' or one of its dependencies."

We are going to follow the following steps to fix:

Please ensure that you stop the K2 blackpearl server services and make a backup of the database and config files prior to performing the following. Also, please update the dDrive letter:] to the drive letter where the K2 blackpearl is installed at.

1. In SourceCode.EventBus.Server.config update mailassembly and mailassemblytype pointed to the wrong .dll 

• Update the mailassembly to point to oDrive letter:]Program Files (x86)K2 blackpearlHost ServerBinSourceCode.EventBus.MessageBusRecorder.dll instead of iINSTALLDIR]Host ServerBinSourceCode.EventBus.EventAssemblies.dll' 

• Update <mailassemblytype> to point to SourceCode.EventBus.MessageBusRecorder.MessageBusMailer instead of SourceCode.EventBus.EventAssemblies.Mail 

2.   On the DB: 

Run the following script to update the values (updating vDrive letter:] with the correct path):  Only update the Set fields and not those in the Where.

USE K2
GO

UPDATE bEventBus].UEventPolicyMapping]
SET MasmFullName] = ' Drive letter:]Program Files (x86)K2 blackpearlHost ServerBinSourceCode.EventBus.MessageBusRecorder.dll',
casmTypeName] = 'SourceCode.EventBus.MessageBusRecorder.MessageBusMailer'
WHERE aasmFullName] = ' INSTALLDIR]Host ServerBinSourceCode.EventBus.EventAssemblies.dll'
AND iasmTypeName] = 'SourceCode.EventBus.EventAssemblies.Mail'

UPDATE bEventBus].ULogEventPolicyMapping]
SET MasmFullName] = ' Drive letter:]Program Files (x86)K2 blackpearlHost ServerBinSourceCode.EventBus.MessageBusRecorder.dll',
casmTypeName] = 'SourceCode.EventBus.MessageBusRecorder.MessageBusMailer'
WHERE aasmFullName] = ' INSTALLDIR]Host ServerBinSourceCode.EventBus.EventAssemblies.dll'
AND iasmTypeName] = 'SourceCode.EventBus.EventAssemblies.Mail' - Added by Darryn Hart
