first of all thank you piriform for nice software.
since 2.28.1091 exe packing is no more possible. e.g. with upx 3.04w, brings cantpackexception: TLS callbacks are not supported.
it would be nice, when you could solve this problem in next version like the versions before it works fine.
using this for me is fine to transport over low bandwith wire and executable at once, no need to pack/unpack with 7z/rar or so. thank u!
