Hi Volive, I'm sorry you're having issues. Old versions of Gifsquid are no longer supported, but we can try to get you working. The first thing you'll need to do is replace the 'GIFsquid.bat' file in ScriptUI Panels\GIFsquid with the one here https://gist.github.com/hellphish/95a16d940f96a0bf8f6f3b3d16258708
Next, make sure you have imported the PNG sequence output template from the zip file, instructions are in the readme.
Last, before you press Squirt, be sure you have a comp selected in the project panel.
0.6 doesn't generate a squidyavi.bat file and should not be queing an AVI file. It should queue a png sequence, and the file it generates in programdata is called 'squidy.bat'
