This usually happens when the OS doesn't support SHA256 digital signatures, which the installers now use. Vista with Service Pack 2 should support SHA256 digital signatures.  If you have SP 2 installed, see https://support.microsoft.com/en-us/help/2763674/you-cannot-run-an-application-that-is-sig ned-with-...  for assistance.  If you don't have SP 2 installed you'll need to upgrade to SP 2 or a newer OS.
