Under some circumstances when installing an app from a Packagefortheweb archive, such as Sun’s JRE, I get a goofy error message like “Cannot run 16-bit Windows Program” or a message about a failure to find a path with long filenames in it.
It’s a bit of a pain but you can fix it.The trick is to extract the file rather than run it. I found PowerArchiver can do it. Winzip may also be able to. I wish I had a command-line utility to do it but I don’t.
Extract it to a short directory name, then move it to the root drive. Then run your setup.exe. That should be the end of your problems. Clean up afterward to eliminate directory clutter.
