I always use ProcMon for these issues. Find out what file or registry access is causing the error.

To recap, the error message a user will get is "Run-time error 70 - access is denied" Per the vendor they said make sure Mozilla (a required component, and they don't mean Firefox) was installed via right-click and "run as administrator". I am sure I do that anyway (habit) but I uninstalled and reinstalled Mozilla just to be sure. Below are the steps I performed 1. Login as user = Access Denied 2. Log off as user, log in as local admin, reinstall Mozilla 3. Step 1 repeated 4. Login as myself = the app opens fine. Then I log off of the app and the server 5. NOW I log in as user = App opens OK Here's the bizarre-o part. Reboot the server and repeat ONLY step #1 and the application works....for a while. Could some other app be stepping on this one in some fashion? This server doesn't have much in the way of "nonstandard" applications but I wonder if there's some other app that might somehow be stepping on the problematic one. Any ideas?
