Unable to connect to iFix: "Requested operation requires elevation" - error 0x800702e4
Error 0x800702e4 is due to OPC's use of DCOM. The OPC Server is requiring a different elevation status than the one offered by the TopView Configurator upon launch.
Even though TopView may be running under a user account that is part of the Administrators group, it may not have the same rights as the built-in Administrator account.
The fix for that is very simple, we just need to do the following:
- Launch gpedit from an elevated command prompt.
- Navigate to Computer Settings\Windows settings\Security settings\Local policies\Security options
- Locate the following policy: User Account Control: Run all administrators in Admin Approval Mode, which you'll find Enabled.
- Set it to Disabled.
You may need to reboot the computer to apply this change.
You may also have success by disabling UAC according to this article, but please verify this is allowed with your IT group.
