Hello, I am the developer of the software.
The software works on any Windows version, give it a chance and read the “IMPORTANT ReadME.txt” file from the archive.
If your antivirus warns you, please note that is a false positive and the file is actually safe.
Disable your antivirus for 1 minute while you activate the license and allow internet access.
Or you can try and buy the regular version (not giveaway), that will not require online activation and will not trigger antivirus warning.
