csr harmony bluetooth software not uninstalling

So I just want to return to before I installed CSR Harmony Wireless Software Stack, I'm thinking I have to do restore point on windows 10 to earlier date. Also I have tried setting CSR_BTPORT_01 as generic bluetooth adapter but gives This Device Cannot Start (Code 10). When the system rebooted It saw the CSR chip in the USB port and reinstalled the software, So I took the dongle out of the USB port and ran the uninstall program again. It stopped me and asked me to uninstall the existing bluetooth software. I have tried letting windows update search for updated drivers through update driver in Device Manager but Windows cannot find drivers for your device. After down loading software from Dell I ran setup. To accomplish this select 'Update Driver Software' from 'CSR BlueCore Nanosira' (the working device), then. My solution was to change the driver of 'CSR BlueCore Nanosira' under 'Universal Serial Bus controllers' back to the generic Bluetooth driver. In device manager it is under Other Devices as CSR_BTPORT_01, I tried reinstalling using CSR Harmony Wireless Software Stack but it says the CSR Harmony Wireless Software Stack.msi is missing, and search for it but it cannot be found. Windows was claiming that the device was working properly. Then once installed it lost my phone and dongle in bluetooth under windows 10 in Bluetooth and other devices settings, saying Dongle driver is unavailable and Galaxy s9+ Bluetooth is turned off. which was the CSR Harmony Wireless Software Stack. I bought the TP-LINK UB400 Bluetooth 4.0 Nano USB Adapter yesterday got it working perfectly, today I decided to stupidly download the driver for it
