So i had already posted before that you could use the 32-bit version to install a previous version of StreamFab and that way you have a "working" 32-bit version and a buggy latest version.

A user here had hinted at 6.1.3.3 having working downloads for Discovery networks such as Food Network & TLC.

So i decided to remove my trusty 32-bit v6.1.1.8 and install v6.1.3.3 over it.

Turns out, i forgot DRM MPD is only available in the 64-bit version of StreamFab. I figured i'd try my luck at having multiple 64-bit versions. Great Success!! (Ya i still think Borat is funny. I am 51 years old not a millennial)

Here's how you can do it too:

Rename your "StreamFab (x64)" shortcut to "StreamFab (x64) Latest"
Install a previous version of StreamFab but make sure you install in a different directory. I append the 4 digits of the version
Make StreamFab create the new shortcut but don't let it run StreamFab after install. Not mandatory but all kinds of weirdness happens if you do
Rename the newly created "StreamFab (x64)" shortcut to "StreamFab (x64) vWhatever Version Number"
That's it! You now have 2 StreamFab installs of the same architecture

The only thing you need to look out for is if you install an old version that doesn't have certain settings, you should go back to verify your settings after you go back to the latest or any version after that. Just check your settings every time you start a different one and you should be fine.

Small price to pay IMHO to be able to have multiple versions. The queue and your login data should work in all versions.

Obviously don't do the online updater (You should never do that anyway) and when you want to update to the latest version, use the path without the version numbers to update the latest version and not the previous ones. v6.1.3.7 is such a shit show anyway i doubt you'd want to keep it.

Here are some screenshots of what i explained:

P.S. Your firewall will probably ask you to authorize StreamFab since it is installed in a new directory for the previous versions.

P.P.S. Before you ask why v6.1.1.8, it's strictly for when i download a lot from Hulu. The processing phase is ~50% faster.
