Have 4.4.6 and "about" shows that an upgrade is available to 4.5.2.1. but cannot upgrade as the extraction is corrupt. Normally when this happens I delete the downloaded file and try again, but I cannot find the download.
There is no "local settings\temp" on my win10x32 system and I didn't see anything in appdata or \ProgramData that looked like a download.

Not that I am using BaseCamp, but that is the topic of another post.

Unaccountably, the images of the error messages did not upload, or I cannot see them in preview mode.
