It appears that the software update is not working for your EasyNote TK87-JO-050PL laptop, released in April 2011 with Model No. PEW91 and a 15.6-inch screen.
It's possible that the software version you are trying to update to may be incompatible with your device, or there could be an issue with the download itself (e.g., corrupted files). You can try troubleshooting the issue by restarting your device, clearing any cache or temporary files, and checking for available updates through the manufacturer's website. If none of these solutions work, then it may be necessary to contact customer support.
