      I get the Error 1706. No valid source could be found for product Adobe Photoshop Lightroom 5.4. The windows Installer cannot continue.  then I get a Fatal Error Message that the Lightroom 5 catalog.lrcat as a last step in the process.  I don't know where to go from here.  If  I can't reinstall a previous version and then upgrade what can I do.

       

      I tried reinstalling the earlier version  v3 and then upgrading, but I can't do that either.
