Symptoms

The Ninja Kiwi Archive requires a local Flash Player installation. It is unable to install Flash Player though; Attempting to let it download and install flash from a preset mirror causes it to get stuck while trying to download flash.

I have also tried providing an installation file for the Archive manually, but when it tries to install it it errors out with "Module Not Found" and restarts back to the main screen. This may be an issue with the flash installer I have though. The Error message pops up in it's own window, I'm not entirely sure if it's from the Archive or from Proton.

Reproduction

Mirror Download (Main Issue)

1. Start Ninja Kiwi Archive
2. Select a Mirror
3. It will attempt to download flash, I have never seen it continue past downloading no matter how long I left it.

Provide an Installer

1. Start Ninja Kiwi Archive
2. Browse to a local installer (exe) for Flash Player
3. It will attempt to install flash, and immediately stop with "Module Not Found" and Re-Start after clicking OK.
