This error occurs when accessing the Central Console after users have installed a Windows update:
Error - LoadAddIns
Unable to cast COM object of type 'aACentral.advLoginClass' to interface type 'aAcentral._advLogin'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{160D87A2-5701-4F04-9101-18A285C8BE77}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
This issue is caused by the Windows update, creating problems for a number of software vendors. The update removes the registry keys. Microsoft is aware and working on a resolution.
This issue has been identified with the following Windows updates:
Anniversary (1607)
Creators (1703)
Fall creators (1709)
April 2018 (1803)
May 2019 (1903)
The three different workarounds below are in order of simplicity. You only need to perform one of them to resolve the issue.
Option 1: Replace removed registry entries (two methods available)
Manually: Download and double-click on the following .reg file APS-Reg-Keys.reg, on an affected desktop, and follow the instructions. Administrator permissions are required.
Automated: Extract the registry settings from the .reg file above and deploy/execute these with any batch file/systems management tool you use to all affected desktops after you perform a planned release of a Feature Update. Alternatively, these registry entries would be safe to reapply daily if that is more convenient.
Option 2: Register the aacentral.exe file
Open an administrative command prompt. To do this, right-click on the Start button and select Command Prompt (Admin).
Run the following command: C:\adv2000\aacentral.exe /regserver.
Note: You will not get a prompt telling you the registration was successful.
Option 3: Repair the Practice Management Software
Run a repair of the Practice Management software. Please ensure that the repair is run on the Practice Management base software and any Service Packs.
Reboot the workstation.
