    ACR 5.3 RC will not install

    (David_Ross_Williams)
      Running Vista x64 Ultimate and PS CS4 both 32 and 64-bit versions) with ACR 5.2 .

      I've successfully downloaded Lightroom 2.3 RC, but when I download, unzip and try to install ACR 5.3 RC I receive two immediate messages that install has not been successful.

      Repeated attempts yield the same result.
