Hi, good question.
Not for U3 but HippoEDIT is an portable app.
Once installed you can simple copy the install folder to an USB-Stick or to your second computer.
HippoEDIT keeps all related files together in one main folder (the install folder).
You may want to read the FAQ
Can HippoEDIT run portable? too?
or even this FAQ
Where my HippoEDIT configuration stored?On the other hand:
The HippoEDIT Setup.exe is created with NSIS and advanced users could just un-packed it with f.ex. UniExtract.
There is no need to "install" HippoEDIT.
