RLPack Basic Edition

An executable file compressor with protection options
RLPack is a software compression solution that will give you the power to compress your executables and still keep them in executable state. This means that no third party programs or .dll files are needed to run the packed software.

The file works just as it did before it get packed and in some cases it even starts up faster than the original since smaller file needs to be loaded into memory. This is achieved by storing a very small decompressor inside every packed file which unpacks the packed content directly into memory.

Due to high compression algorithms used file size can be reduced down to 30% of the original size. This is higher compression ratio than one in WinZIP.
But RLPack can do much more. In its Full version RLPack can protect your application from modification by checking CRC of the packed executable.

RLPack can make sure that there is only one copy of your program running. It can also protect the packed file from being unpacked by all known generic unpacker used by crackers to deprotect the application, after which application can be cracked.

Another feature is the ability to sign every packed executable so that you can track how your executables distribute over the web or so that you can find out if the copy of the program has "fallen" into wrong hands.

Signature can be read even if the application has been unpacked and it is not longer protected by RLPack wrapping shell. But this is not all. RLPack can decrease the size of your program's installation by enabling you to remove common runtime .dll files such as MSVBVM600.dll from the installation.

If this common .dll file is not located on your customer computer RLPack will show download dialog which will download missing .dll file(s) from your website after which application will be started normally.
