Hi, Samiullah. I'm Robinson, and I’m happy to help you today.
The error "the software package cannot be installed on your system" is usually shown when the driver that you are installing is corrupted or is not for Windows 10. In this case, you will need to go to your Bluetooth adapter manufacturer's website, download the latest version of the driver and install it.
If the problem persists or you cannot find the correct driver, provide the full model of your Bluetooth adapter and I'll be glad to help you to find the correct driver.
I hope this information helps. If you have any questions, please let me know and I'll be glad to assist you further.
