A new Windows user might want to run the tomcat service and Excel.

Here we outline how to adjust DCOM permissions for a hypothetical new user, EASA-user.

• As EASA supports 32-bit Excel start a DOS command line and start the 32-bit Microsoft management console.
  • type mmc comexp.msc /32 (we use Windows 10 in this example)
    • navigate to Component Services→Computers→My Computer→DCOM Config
      • right-click Microsoft Excel Application below

If Excel is missing from the list confirm a C:\Windows\System32\config\systemprofile\Desktop file exists.

Confirm there are 'Full Control' permissions, right-click the file and select 'Security'.

• select Properties
  • Customize all three types of permissions below to include a user that wishes to run the tomcat service and Excel.
    • Launch and Activation Permissions
    • Access Permissions
    • Configuration Permissions

Click Customize for Launch and Activation Permissions below.

After Customize, click Add to search for a user who will run tomcat service and Excel.

• select the user, in our example EASA-user, and check Allow Launch and Activation permissions for a user
• check Allow for all of them, below

• repeat for
  • Access Permissions
  • Configuration Permissions
