There are more then one way to use this TychoPatch.
The "TychoSh3Patch.bat" is in the older Version (v3).
If this does not work for you then try the last Version (v4) before all.
See post#85:

It contains a "TychoSh3Patch.html" (not a *.bat) which runs in a not hardened Browser.
And in post#71 was shown two more ways.
