I had the same problem and couldn't figure it out, I'm posting my solution here in case it may help others.
My problem was that since the server I wanted to install the SDK to was protected by a web filter in my companie's intranet, I was downloading the SDK .exe elsewhere and copying it manually to the server. I later realized this doesn't work since I believe the installer then checks the cache on the server, but since there is no cache to compare to, it fails with this error. Simply requesting our sysadmin to take down the filter temporarily so that I could download the file directly on the server fixed the issue. -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/RE-regarding-apache-flex-sdk-installation-issue-tp5881p6173.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
