In order to use Excel, the EASA service must be configured to run as a Windows user.

Upon its first or initial invocation, most versions of Excel launch an interactive popup window, yet by default an EASA Tomcat service including the Excel Server runs as the non-interactive user, SYSTEM.

SYSTEM cannot close this interactive popup and thus the Excel Server cannot conduct any Excel-derived processing unless a different account is configured to run the service ('EASA-user' for this example).

An Excel customer must therefore complete two essential tasks:

A. Create a new Windows user 'EASA-user' before installing EASA:
       Run Excel as 'EASA-user'
       Close the initial popup window.
B. Configure the EASA Tomcat service to run as 'EASA-user' after EASA is installed

1. Create a new Windows user with administrator privileges (called 'EASA-user' for this example)
2. Log in in as: EASA-user
3. Find and open Excel manually
4. Close the pop up which appears when EASA-user opens Excel for the first or initial time.
5. Log out of Windows
6. Log in with the first user that was created when Windows was installed

Following EASA installation of the EASA Tomcat service, configure this service to run as 'EASA-user':

1. Open Task Manager
2. Click Open Services
3. Right-click on the EASA Tomcat8 service
4. Select Stop
5. Right-click on the EASA Tomcat8 service
6. Select Properties
7. Click 'Log On' tab
8. Tick Log on as: 'This account:'
9. Enter EASA-user's credentials
10. Click Apply
11. Click OK
12. Right-click 'Services > EASA Tomcat8' or 'Task Manager > Tomcat8'
13. Select 'Start' to restart the EASA service
