Thank you for the answer!
I'm sorry for my late reply.

No video, but here are some screenshot of what happens.
The download starts normally:

but when hits the end, Firfox says that the download fails.

The problem is BitDefender:

Thank you for the work you are doing.
I am a registered free user and unfortunately I can no longer download any files, even small ones.
The problem I am experiencing is this.
The download starts and goes through to the end, but an error ‘Download failed’ appears on completion. In the Downlaod folder I find a file with the correct name but 0Kb and a ‘hidden’ file the size of which corresponds to the file to be downloaded,  neither of which I can use.
I have tried various links and various browsers (Firefox, Edge, Chrome), but the result is always the same.
I'm afraid it's a problem with my antivirus (Bitdefender) which blocks a suspicious connection just when the donwload is to be closed.
I don't know if there is a way to solve my problem.
Thanks anyway for your attention.

Thank you, the link now works!

The link to the version «EaseUS Partition Master 18.0 Build 20231213 (x64) WinPE» does not seem to work for me.
Also I don't see the portable version: can you add it?
Thank you very much!
