As you may have seen, I've added a bunch of MD5 checksums to the installer in hopes of detecting bad downloads and reporting them to the tracker so we can see if bad downloads is the root cause of many of the install failures that have been reported.
The current built-in MD5Stream, written in AS, is extremely slow for large downloads like the AIR SDK. On my Mac, the CPU is up around 95% or even 100% and still it takes several minutes. I spent the weekend figuring out how to do the MD5 in CrossBridge. It takes only a few seconds to compute the checksum. I think it is worth adding CrossBridge as a build prerequisite to the Installer. This will not affect SDK builds. Note that, for Windows builds of the installer, it will require Cygwin. What do others think? Thanks, -Alex
