I will buy CCleaner Professional Plus and I would like to know if is posible to have it in portable form
I would not have thought a portable Pro version would be possible based on the EULA.
read here for the specific related bit; https://forum.piriform.com/index.php?showtopic=46658&p=274697
but basically I read that as saying, you either only have a license for 1 PC, for 1 year
or you have an 'unlimited PC' licence which is only for all the PC's you own in the one household.
so going portable would serve no benefit.
this subject comes up often enough that I am amazed Piriform doesn't update their website with a much simpler 'so a grade 5'er could understand' description.
and show it as a table/grid of products, prices and benefits. no-one cares about the legal waffle, that should only be displayed during installation.
Last I was made aware, it is fine to have the pro portable however not portable and installed at the same time.
To make it portable copy ccleaner.exe, and ccleaner64.exe and any dll you find in the folder and create in the new folder and dummy text file called portable.dat in the folder (make sure file extensions are shown so it doesn't secretly be "portable.dat.txt"). If your registration doesn't carry over, though it should, you should be able to register your license number into it.
