Hi Goutham,
Yes, I'm pretty sure that you will not be able to install the driver without uninstalling the previous driver as you stated. I understand the problem that you are describing. It has been a long time since I have had to do this and I don't want to uninstall my previous driver to try to reproduce the problem that you are experiencing. I have not had any issues in a long time and the current driver that I am using is: 3.3.1.508 that was released on 4/10/2022. I don't know if that is the one that I uploaded in the past or not.
Anyways, if the adapter completely disappears after uninstalling it, then you may want to try clicking on the action menu on the top of the device manager window and then click "scan for hardware changes." In the past, when drivers are uninstalled, the device will usually show up this way... though it may not show up in exactly the same place. If you see any icons that look differently, it may indicate that the device manager recognizes something that isn't installed properly. You can click that and check the description and it might be the network adapter. I cannot say for sure, but it is worth a shot. Hope that helps!
