I tried to update the PortableApps.com Platform from within itself to version 2.0 Pre-Rease, to only run into a complete failure.
The PA.com Platform searched, found, downloaded and successfully started the just downloaded update file. I was prompted to close all instances of the PA.com Platorm, so I did [right click on the PA.com Platorm icon and exit] For a littler bit it looked like the update was going fine but then as I was prompted yet again, but this time with an error message, saying that something when wrong with the update. [sorry, I didn't write down the message, but it dealt with the autoupdate file]
I know this is a Pre-Release and that bugs are imminent. I'm just reporting my experience with it thus far.
With that said and on the side; what an outstanding update for the PA.com Platform. This one truly is a big step for portableapps.com and its users.
