Overview

This article indexes the knowledge base articles that provide resolutions or workarounds for common installation errors of MailEssentials. It also describes how to gather and review logs in case a direct error is not presented during the failed installation process.  

Introduction

Some installation errors are presented by the installer itself, while for others, you need to gather and review the install logs. If you have encountered an error message during the installation process, please check the list of the knowledge base articles in the next section to see if any of them provides a solution to your issue. Otherwise, follow the instructions in the Reviewing Logs section for details on how to gather more information on the error and how to narrow down the issue. 

The same procedure will apply if you are getting errors while upgrading to a newer MailEssentials release.

Reviewing Logs

If there are no direct errors presented during the installation in spite of a failed installation, follow the steps below:

1. Gather the installation logs.
   
   Please review the article, "How do I get the installer log for MailEssentials?" for more information on the process.
2. Open the installation logs with a text editor.
3. Perform a search for Return Value 3.
   • Review the lines before Return Value 3 to determine the reason for the failure.
   • If Return Value 3 is not found, search for Error.
     
     Please keep in mind that not every match for the Error keyword is a failure. Continue searching for it until you locate the full error message.
4. Once you find the error code, check the Common Installation Errors list provided above.
   • If there is a match, follow the instructions in the related article.
   • If the error is not found in the list, proceed with the next step.
5. Note down the code of the error that you found in the installation logs.
   
   The errors found in the installation logs have error codes, such as "Error 1920". These error codes have a direct reference to the Windows System Error Codes.
6. Review the Windows System Error Codes and locate the error code that you noted down to have more information on the installation failure.
