I´ve been using Bitcoin-qt (version 0.8.1.) for several weeks but lately I´ve had problems due to a so called "corrupted block database" issue, so I´ve decided to update my client to the latest version (0.8.5.).
It´s already installed (I just installed it on my laptop without removing the older version), synchronized and working properly.
Can I remove the older version of the client by clicking on the uninstall icon? Is it safe to do so? If so, do I have to backup my wallet.dat file again or the previous backup still works with the latest version?
Thanks in advance.
