Don't show 32 bit wording unless there is explicitly both versions available

[ferventcoder]

Downloading packagename 32 bit is confusing for some when they are on 64 bit Windows and want the 64 bit version. Many times there is only a 32 bit version available (which works fine), so the message shouldn't show unless there are both downloads available and the user has forced 32 bit or is on a 32 bit system.
