NourinE Posted July 25, 2014 Share Posted July 25, 2014 Hello,I have a problem with installing Bluetooth Driver and Sony Wireless State Device.I always downloaded them from the laptop's official website and installed them, but this time after a clean installation of windows 8, they all refuse to install with a yellow exclamation mark on the Unknown Device with (code 28). I mean the process of the installation goes until the end and I thought they were successfully installed but they weren't.please, how can I install them?

Moderators Andavari Posted July 25, 2014 Moderators Share Posted July 25, 2014 Does the setup file come with any specific install instructions that are a bit out of the ordinary such as having to install through Device Manager. I only ask because that's how I had to recently install my NIC card as it didn't have any setup .exe files to run, they were all .inf files that had to be installed using: Device Manager -> Network Adapter -> Update Driver (may read as "Update Driver Software" in Win7 or newer) -> Browse (to the setup .inf file) Link to comment Share on other sites More sharing options...

NourinE Posted July 25, 2014 Author Share Posted July 25, 2014 I succeeded at installing by giving permissions to Bluetooth through the registry, but now I have white exclamation marks on Bluetooth Peripheral Device. Link to comment Share on other sites More sharing options...
