Windows 7 Professional
Driver:
iFi-AMR-HD-USB-Audio-Driver-5.12 fails during loading.
"Digital signature of driver file iFIUSBAudio.sys is not accepted by this operating system"
Ifi is visible in Device Manager as an unknown device
That happens with ancient operating systems. I had to update the operating system to Windows 10 on a 12 year old Toshiba laptop that originally came with Windows Vista. Back in 2020 it finally reached a point where nothing would run on Vista anymore. I couldn't even update the browser. The old browser didn't work with secure web sites and a new browser build wouldn't install because Vista was too old.
iFi may have a driver for Windows 7 but it probably won't work with the latest firmware in their products. It's time to get over your fear of a new Windows version.
I have a sinking feeling that you ignored the free update to Windows 10 that kept appearing in Windows Update. Heck, it might still be there.
But first, before you click that update button make an image file of your existing Windows 7 install. I use the free Paragon Backup and Recovery
https://www.paragon-software.com/us/free/br-free/#Once Backup and Recovery is installed follow the instructions to make a bootable thumbdrive. Yes, it's a time consuming PIA but better than making a brick if the Windows 10 install fails. You will also need a 2nd hard drive to store the image file, you should have one to store backups of all your computer setups anyway.
Now that you have a backup image, go ahead and click the Windows 10 update button. No button? Time for plan "B".
Plan BGo to the Windows 10 Update page:
https://www.microsoft.com/en-us/software-download/windows101.) Windows 10 November 2021 UpdateThe Update Assistant can help you update to the latest version of Windows 10. To get started, click Update now.
I prefer to do a clean install but you should first download the Asus drivers for Windows 10 and put them on another thumb drive. Windows 10 will install newer and better drivers but better to be safe.
No need to download drivers if using the Update Assistant above. A squeaky clean new install is so much better than an update that leaves years of old code behind.
To do a clean install click on
2.) Create Windows 10 installation mediaTo get started, you will first need to have a license to install Windows 10. You can then download and run the media creation tool. For more information on how to use the tool, see the instructions below.
The old Windows 7 license key will activate the new Windows 10 and make it legal.
No Windows 7 license? Then use the Update Assistant, option #1
There are ways to recover a Windows 7 product key, one of these should work:
