I do not have problems with portable software. I use winpenpack software s x-cafe and x-launcher to port software. x-cafe is a portable associations program that keeps file associations on a ini file in its folder instead of the registry which resets in winpe. The x-launcher is a set of files and directories that writes install info to ini files and makes sure there isn't errors caused by the software attempting to write in a read only area, or one that doesn't exist. Once you learn and set up x-launcher most software you can make portable yourself.
