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 (Using 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:

• 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
