This has been released. Thanks for testing!

InfraRecorder has been updated to version 0.45 (changelog). Hopefully this fixes many of the issues people have had. There shouldn't be any more UPX problems either, since now the only things UPX'd are the main 2 exes and the codecs. I've made a few code improvements when going through it and improved the registry handlers for the Cygwin keys for the possible situation if some other program creates cygwin values after infrarecorder portable has already been launched. Please test everything out and let me know.
InfraRecorder Portable 0.45 Pre-Release 2 3 MB, 6.6 MB installed

also, John, can you fix the fact that https://portableapps.com/InfraRecorderPortable does not redirect to the InfraRecorder Portable page?
