After rewriting the new version in the same folder with the version of Multi Commander, I have lost the settings: color panels, scripts, custom commands, a button on the Quick Launch ...
Maybe it makes sense for the portable version stores all the settings in a special separate folder? Also, if a portable version available in two versions (win32 and win64), how to make them the same settings?
It seems to me logical to make a universal boot loader which will run the program desired bit. Or make a different name, as is done in ConEmuPack.
