For a while Illustrator wouldn't open without an error message. Then after a while I couldn't click open a pdf file. I had to right click "open with". So, I tried reinstalling the whole package. It errored with message 1603. The installation of Adobe Flash, Illustrator, Photoshop, and InDesign failed to load some components. I unstalled the whole package and reinstalled with all security and firewall shut off. It still errored with the message 1603 and I still have the same issues with pdfs. What to do?
uninstall, run the cleaner (http://www.adobe.com/support/contact/cscleanertool.html), restart you computer and then re-install.
didn't help. When I right clicked on the tool, I selected Run as Administrator... a black window came up briefly and disappeared with no instructions or prompts. I clicked it a couple of times, but still the same thing. I'm reinstalling the cs4 and it did the same thing that it won't install all Adobe Flash, InDesign, Illustrator, or Photoshops.
