Error: file is corrupt

I tried to download solid edge twice and i received always the same error when i try to install it after the download ends... it just says that the file is corrupt, but i tried to download it from a link posted here where somebody said it worked, so the problem must be my computer, even if i have 6 gb ram, intel core i5... do i need 7zip to open the installer? is there a reason why the file is corrupt, even if the download proceeded slowly without stopping? thanks for replying

Re: Error: file is corrupt

It is recommended you use a download manager to ensure the file is not corrupted during the download.
