If you have found a 3rd party try you can download then analyze using a sandbox like total virus, joe sanbox and anything then you can equate the hash of the file if the match, it means that the file comes from the original source

to check

sha256sum you file

md5sum you file

I have found it!

I'm not sure if it's safe or not, but the report shows 2 Virus Total, Joe sandbox

Total virus : There is an issue

Joe : Its clean

And I checked that the hash file is the same, maybe it's safe. If there is an issue about the virus maybe it is because of the processing of other files such as libraries, code, .dll there is more hash on this report you can check it. If you want to check further please can check after install. You can check the files there and match the hashes in the sandbox report results

I was try and run it, 

This tool like Ida, GDB, Ghidra, I can't guarantee that what I install is safe, but I have tried nothing (weird or malware) on my laptop and I have checked this in Joe sandbox. If you're not sure it's safe, try installing it on a virtual machine

What is mean?

Only check signature, you can check it on link 

The MZ signature is a signature used by the MS-DOS relocatable 16-bit EXE format.

The reason a PE binary contains an MZ header is for backwards compatibility. If the executable is run on a DOS-based system it will run the MZ version (which is nearly always just stub that says you need to run the program on a Win32 system).

Of course this is not as useful nowadays as it was back when the world was transitioning from DOS to whatever would come after it.

Back then there were a few programs that would actually bind together a DOS version and a Win32 version in a single binary.

And as with most things dealing with Windows history, Raymond Chen has some interesting articles about this subject:
