Cannot install Office after 64 & 32 bit trials

    I accidently installed the 2010 32 bit Office RTM last week. It run very fast
    and then I realized I didn't have the 64 bit version. I got the 64 bit
    installed with some effort but it seemed to lag so I tried to go back to 32
    bit again and now I am locked out of installing either version. It errors out
    reporting a previous trial has been installed on this computer. How can I get
    Office back on my system?

    There's nothing wrong with using 32-bit Office on 64-bit Windows, you
    should have left it there the first time you installed it.

    Now there are entries in the Registry referring to both the 64-bit and
    32-bit trial versions, and until they are all removed you won't get any

    Try running System Restore to go back to a date before you installed
    them. That should restore a copy of the previous Registry data with no
    Office references. Then check C:/Program Files and delete any Office

    Do the same in C:/Users\<your account name>\AppData\Local
    and in C:/Users\<your account name>\AppData\Roaming

    Now try installing Office trial again but decide from the outset
    whether you want to try 32-bit or 64-bit. You can't try them both on the
    same PC so make up your mind first!
