Can you expand a little on this...? What file are you trying to extract??
OK....my first though is that the download was interupted, and has become corrupt because of that.....in which case, I suggest re-downloading the file.
Are you on Windows 10 by any chance?...and if so, have you had Solid Edge installed prior to Windows 10??
I have the same problem and yeah i have windows 10 and i want to install Solid Edge for the first time
I've already re-downloaded
Before you install Solid Edge, you will need to download and install Microsoft .NET framework 3.5 >heres a link< ...then provided your downloaded SE installation file is complete [ie; not corrupt] then the install should go through as expected.
