Hi Juan,
I'm not sure why this is, but updates fail for me with using default settings. The default path for downloads is C:/Users/Eddie/AppData/Local/Temp
The Package download succeeds, but when PI is closed and update attempted, the update fails reporting "Can't find required components". Then PI appears to shut down, but is actually still running and needs to be killed from the task manager.
I suspect a permissions issue on the path, but I don't know why as its running as admin, the folder is owned by me, and the packages were successfuly downloaded.
If I change the download path to somewhere else, it all works properly. I had this problem with the previous version and fixed it that way, but as I just erased the old PI settings for the latest version, it has just happened again and I thought I'd better let you know before I forget all about it...again...
