When using the PortableApps Platform to update FileZilla Portable, the Platform issues the following error message:
PortableApps.com Platform
The downloaded copy of FileZilla Portable is not valid and can not be
installed. This could be due to an incomplete download or other
network issue. Please try running the updater again when complete.
Running the updater again results in the same error message.

As the error states, the usual cause is an incomplete download or network issue. This is most often due to:
1. A local software firewall that is either entirely preventing the download or causing it to be cut off in the last few KB
2. A one time network issue with an incomplete file which is now cached by Windows/IE locally
Try clearing your cache in Windows or IE's Internet Options and try again. Does it show any progress in the download bar?
I have verified that the file is available on my local SourceForge mirror and downloading and installing correctly.
Sometimes, the impossible can become possible, if you're awesome!
The PortableApps Platform uses IE (Internet Explorer) to perform downloads?
It uses the same Windows components that IE uses, so if IE can't successfully perform the download, neither can the platform.
Interesting. Does it share the same cache as IE?
The PA.c Updater/App Store is configured so that it tells the Windows internet components not to cache a file as it is downloaded. But, there have been instances where that has not worked right. That's why I suggested clearing your cache in IE.

Thanks for the details. I cleared the cache, but no difference. Everything else is working as expected. I think I will try an uninstall/reinstall.
Thank you for your help and the details.
Just a quick update. Before trying an uninstall/reinstall, I gave the update one more try. This time it worked correctly.
Nothing changed on my end except for incremental antivirus definitions.
So either something in the AV definitions was causing a problem, or it will remain as one of the many mysteries of the internet.
