The developer, Vishal Gupta, is posting in this thread
. he says no plan for a portable at this time. I notice the search for portable finds nothing but very iffy sites. If Portableapps comes out with it, then it would be ok. I see the developer says this about the program:
Puran Utilities does not run any background processes/services and hence when it is not running it is as good as not installed on your system.
I decided not to try this new program. I tend to stay away from such programs, even though I used Puran defrag when I had my OS on a HDD.
