iPhone Does TinyUmbrella still work?

[forjailbreak]

I've installed TinyUmbrella 9.3.4 on several PCs, with different windows versions, and on all of them the installation seems to work, and the program starts, but it seems to just load some libraries during a splash screen and then nothing happens. I never get a window to do anything in.

I've tried running it as an administrator and connected the iphone first. I'm doing the "TinyUmbrella [WIN 64 Installer Bundled JRE]" that comes with the java files:
http://www.firmwareumbrella.com/

There is an error.txt with this:

Anybody know what could be causing this? Is there someplace I can get older versions to try?
