Thank you for contacting Intel.
When updating the Intel® PROSet/Wireless Software, it is recommended to uninstall the old version before installing the new version.
Please refer to our support website - Intel® Wi-Fi Products — Uninstall Intel® PROSet/Wireless Software
See if you can find the PROSet Software in Add/Remove Programs or Programs and Features.
Another option is to download and install the OEM-supplied PROSet Software. You can find it at your system manufacturer's support site.
Example: Sony* - support.sony.com, Lenovo* - support.lenovo.com
We look forward to your test results.
