OK, found a solution: - install Process Explorer - add Evan.exe process/subprocess monitoring - Filter subsequently for file/registry access - Found

HKCU\SOFTWARE\EVAN

with size data - delete this key in regedit.

I am using a (portable?) exe, not requiring an install. [DELETED] It allows to drag its panes, which it remembers between sessions. The pane layout is now in a corrupted state, one pane does not show up and I would like to "reset" it. I was looking in the following places: - no hidden file with the binary - no registry entry - no data in AppData - no change upon deleting the directory and unzipping again. Any idea?
