tydiffusion installation error

[tyFlow]

After extracting the zip (which you shouldn't have to do yourself if there's no permissions issue, but it's ok if you do it manually as long as you extract everything directly into your tyDiffusion root folder) you need to run the one-click installer from Max...you can't run any of the batch files in the _bin folder directly, as tyDiffusion modifies them in various ways before running them. Your log seems to show that you just tried running the raw batch files in the _bin folder, which explains why they failed.
