Only option given is "... Do you want to remove DSA?" After agreeing program still does not install. Have also used Intel's DSAUninstaller program with no change in results. Control Panel > Programs does not show any version of DSA installed. Any attempt to install always results int the "Do you want to remove DSA" option at the start of installation.
Thank you for your efforts, but after following your steps the results are the same. Step 2 locates nothing DSA to remove. According to Control Panel > Programs there are no versions of IDSA installed.
Again thank you.
Using regedit and following DSAuninstaller step by step, found that the registry entry "LOCALMACHINE\Software|Intel\SUR\Installers\QUEENCREEK" was being reported as deleted, when in fact it was not. Manually deleted the registry entry, restarted computer and everything works as advertised.
