Program Installation / Setup “Access Denied” error

Filed under: Uncategorized — Jason Hartley @ 9:17 pm

When attempting to execute a Windows Installer package or run a application setup executable, you get a “Access Denied” message and the installation will not continue. This is likely caused from the DCOM security settings being modified by a third party application install or program removal. To resolve this, do the following:

Run the DCOM configuration, type “dcomcnfg.exe” in the run box.

Open the “Default Security” tab.

In the ‘Default Access Permissions’ area, click “Edit Default”.

Verify or Add the following groups/accounts: ‘SYSTEM’, ‘Domain Admins’, ‘Administrators’ and give them “Allow Access”.

If you have other groups/accounts in the Access Permissions leave them alone. They may be required for third-party installed software.
