🛡️ Does Windows or your browser show a warning?

This is normal for new programs with few downloads: Windows and Chrome distrust any installer they do not know yet. OSA Lab contains nothing malicious, and you can check the file is the original with its SHA-256 checksum.

Chrome / Edge: in the downloads list, open the file's ⋯ menu and choose Keep (in Edge, Keep anyway).
Windows (“Windows protected your PC”): click More info and then Run anyway.
