When accessing the licensing module in the legacy K2 Workspace's Management Console, the following error is shown:
 

Symptoms

• All other modules in the Management console are working properly.
• If you happen to attempt to apply a Cumulative Update or FixPack, the update will fail, and you will see the following error in the InstallerTrace logs:
   
  Error from controlutil output: RegisterControlTypes Failed: Object reference not set to an instance of an object.
  
   
• In your HostServer logs, you will also see a similar error:

Troubleshooting Steps

To resolve this, first, try to decrypt the connection strings in SourceCode.Forms.Runtime.config:
 

1. On your K2 blackpearl server, please go to [Program Files]K2 blackpearlHost ServerBin, copy SourceCode.Forms.Runtime.config.
2. Go to C: (or whichever drive you want), create a temporary folder, and name it K2ConfigForms.
3. Copy the SourceCode.Forms.Runtime.config to the K2ConfigForms folder you created.
4. Rename the SourceCode.Forms.Runtime.config in K2ConfigForms to web.config.
5. Open command prompt with admin privileges, and run the following:
    
   cd C:WindowsMicrosoft.NETFramework64v4.0.30319
6. Then run the following (replace C: with the driver where you create K2ConfigForms):
    
   aspnet_regiis.exe -pdf "connectionStrings" "C:K2ConfigForms"

If no errors are shown during the decryption process, open web.config in the K2ConfigForms folder, and inspect the connection strings. Make sure the following line is correctly referencing the SQL server that your K2 database resides in:
 

If the connection string is pointing to the wrong SQL server or K2 database:
 

1. Create a backup of your existing SourceCode.Forms.Runtime.config.
2. Update web.config in K2FormsConfig with the correct connection string.
3. Rename web.config in K2FormsConfig to SourceCode.Forms.Runtime.config.
4. Replace your existing SourceCode.Forms.Runtime.config with the newly updated one.
5. Restart your K2 blackpearl service.

If you are unable to decrypt the config file, then the encrypted connection strings are most likely corrupted. In that case, you will need to manually repair the config file.
 

1. Create a backup of your existing SourceCode.Forms.Runtime.config
2. Edit SourceCode.Forms.Runtime.config, and remove the following section:
    
   <connectionStrings configProtectionProvider="K2ConfigurationKey">
     ...
   </connectionStrings>
   
    
3. Then above </configuration>, add the following section, and replace the value accordingly:
    
   <connectionStrings>
      <add name="Forms.Data.ConnectionString" connectionString="Data Source=[Your SQL Server];Initial Catalog=[your K2 database];integrated security=sspi;Pooling=True" />
   </connectionStrings>
   
    
4. Restart your K2 blackpearl service.
