hi @Dorothy80Galvin
To resolve Desktop Update Error 15225, follow these steps. First, verify your Internet Explorer settings by ensuring it is set as the default browser and that SSL settings are enabled. Next, add trusted sites by navigating to Internet Explorer, then go to Tools > Internet Options > Security > Trusted Sites > Sites, and add *.intuit.com. Additionally, temporarily disable your anti-virus software and try the update again, as security software can sometimes interfere with latest updates. Finally, ensure the digital signature for the QBW32.exe file is installed correctly by locating the file, right-clicking it, selecting Properties > Digital Signatures, and installing the certificate. If the issue persists, contact support for further assistance.
