What does Installer checksum mean?
An installer checksum is a value computed from file contents for comparison with a reference. A cryptographic checksum can help detect whether the downloaded bytes match a known package, but its value depends on the trustworthiness of that reference.
Why it matters
Compare the same algorithm for the exact file and release. A different operating-system build normally has a different checksum. If an attacker can replace both the file and the reference on an untrusted page, a matching result does not establish origin. Keep integrity checking separate from publisher identity, compatibility and behaviour review.
A practical example
For example, a SHA-256 mismatch against a trustworthy release record can identify a different or damaged download. Do not proceed by ignoring the mismatch or assuming the familiar filename outweighs the actual file-content comparison.
