Pixopedia 2014 0.x.x is distributed as simple zip file. There is no installation procedure. Simply unpack pixopedia2014.zip in desired directory and start Pixopedia.exe.
Download pixopedia2014.zip in desired directory, unpack zip file and start Pixopedia.exe.
Beside executable, there is also some kind of manual in pdf. You can read it on-line, but it’s better to download manual in the same directory with executables, so that you can read it off-line.
Executables and manual are distributed separately, because changes in executables may not be synchronized with manual changes.
Currently, Pixopedia 2014 executables are compiled with 32-bit compiler. 64-bit version will be available (probably) somewhere around June, 2014.
