Firefox 32 and 64 bit on same system doesn't update & Audacity not right either

[Kelemvor]

Howdy,

Two issues.
1) We noticed we had a couple computers with outdated versions of Firefox.  When I checked their PMPC log it showed it had updated Firefox a couple weeks ago.  When I checked actual PMPC it showed the 32 bit version was installed and at 59.0.02 and the 64 bit version was installed but only at 57.0.  However, it says No Apps to Install

2) Audacity doesn't seem to update correctly.  It seems to install the new version but not remove the old version.  Add/Remove programs then lists them both but they act strange when you try to uninstall them.  I had this exact same problem, with these same two versions, on a different laptop the other day as well.

See attached.

Thanks.

Overall, these are what I'm following so I want to know if you can recommend me.
