This user gets it. Some viruses are also known to replace the links in the web browser with malicious ones, downloading some pa07_0010.exe instead.
ZalazniSvetozar, do this:
1. Open File Explorer
2. Navigate yourself to the directory where the pa07_0010.7z file is located (the current Pre-Alpha 0.7.0b3 build)
3. While holding the Shift button, right click on any free space in File Explorer and click "Open in Terminal" or "Open PowerShell window here". Alternatively, you can type `cmd` in the address bar and it'll do the same thing
4. Type `certutil -hashfile pa07_0010.7z SHA256`
5. Confirm that the SHA256 hash is `becaaa25e54373b1a5adfba454fac43504714c718ef265e6a24340945aec1b0c`
If the hash is different, the archive is somehow altered or corrupted. It would be better to download it again with a different browser and check the PC with a proper antivirus.
Note, it's only for the Pre-Alpha 0.7.0b3 build! Other versions are expected to have different hashes.
Edit: For the most recent version (pa07_0011.7z):
`certutil -hashfile pa07_0011.7z SHA256`
