Let us talk about them in detail.
1] Check Bonjour Service Status
The very first thing you need to do to resolve the issue in question is to check if the Bonjour Service is running. In case, the service itself is stopped, we are going to start it manually and configure its properties. To do the same, open the Services app from the Start Menu. Now, look for Bonjour Service, right-click on it, and select Properties. Change the Startup type to Automatic and click on the Start button (if it is stopped). Finally, check if the issue is resolved.
2] Open Apple Apps in Clean Boot
You may encounter this issue due to a third-party app, some users reported that MalwareBytes stopped them from accessing Apple services, whereas, some of the reported Bonjour Service errors occurred due to a VPN. Since, we are not sure which app is the culprit, performing Clean Boot is the only reasonable option. So, go ahead and boot into Clean Boot, then check if the issue is resolved. In case, the issue persists, enable services one by one to find out the culprit. Once you know which app is the troublemaker, just delete it and your issue will be resolved.
3] Configure the registry
If you see “Registry entry is set to the wrong file path (Program Files instead of Program Files (x86)”, then you need to configure the registry to resolve the issue. However, before making any changes to the registry, first, create a backup. To do the same, open Registry Editor, click on File > Export, and then save the registry file with a name to an easily accessible location.
Once you have created the backup, open Registry Editor again and go to the following location.
Now, double-click on ImagePath and change the file path from C:\Program Files\Bonjour\mDNSResponder.exe to C:\Program Files (x86)\Bonjour\mDNSResponder.exe.
Finally, reboot your computer and check if the issue is resolved. Hopefully, this will resolve the issue for you.
