Issue _2:
Customer has custom connection strings located in K2HostServer.exe.config for blackpearl 4.5 1200. After the upgrade to 4.6.6, the connection string is not found in the config file.
 

Diagnoses

Issue _1:
This is a known issue with the installer for 4.5 update 1420.

Issue _2:
In 4.6.6, K2 use K2HostServer.exe.config instead of K2HostServer.config unlike 4.5 update 1200. This is the reason that this config file got modified during the upgrade.
 

Resolution

Issue _1:
Suggested customer to perform the following steps to resolve the issue:
1. Run the installer, progress till you reach the Service Account Configuration Screen that gives you the error.
2. Click Back (goes back to the screen before Service Account Configuration) , followed by Next, this should bring you back into the Service Account Configuration Screen.
3. Try to click on the Next again to progress.
4. Progress as per normally you would for the upgrade.

Issue_2:
