To solve this you will have to make Thumbs.db visible and delete it manually from the .../PatchClient/ folder, then patch again and it should work.
Here is a guide how to make the thumbs.db file visible:

Afterwards you can change it back to default again.
Dual Clienting Solution:
Dual clienting? I started two renewal client instances and let them patch, but only hit "start" and logged in once both were fully patched. Please try that.
