HTTP does not provide the transport encryption and server authentication that HTTPS is intended to provide. A source-listed HTTP installer link should not be described as a secure verified download. Ask for an authenticated current distribution route and verify the publisher before running the file.
Keep the claim accurate
A file can be listed in an old screenshot without its present contents or signature being verified. That is useful source evidence, but it is not a security test. Do not equate a working address with confidence in the downloaded binary.
Do not invent a secure replacement
Changing the text from HTTP to HTTPS is only valid if that endpoint actually supports the secure route. A guessed secure-looking button can simply fail or point elsewhere. Use a publisher-documented address or request one through the established support channel.
Review integrity information separately
A trusted signature or independently supplied checksum can help establish file identity, but each needs a trustworthy reference. A checksum posted beside an untrusted download can be changed along with the file. Keep operating-system scanning active and investigate warnings rather than disabling it.
