MPRESS is a free, high-performance executable packer for 64-bit, 32-bit, .NET executable formats!
MPRESS compresses PE32 (x86,32-bit), PE32+(x64, AMD64, 64-bit) programs and libraries and .NET applications, makes them smaller, and decrease start time when the application loaded from a slow removable media or from the network. It uses in-place decompression technique, which allows to decompress the executable without memory overhead or other drawbacks; it also protects programs against reverse engineering by non-professional hackers. Programs compressed with MPRESS run exactly as before, with no runtime performance penalties.
MPRESS is absolutely free of charge software, therefore you can use MPRESS for your commercial project without needs to make it opensource. MPRESS uses LZMAT - extremely fast data compression algorithm.
