I had a bad update weekend. TWS went into Update mode, and afterwards, the executable launcher had disappeared.
Tried reinstalling it, welkin installer would not allow it.
Tried uninstalling it, welkin installer would not allow it.
Managed to delete everything, including the Regex keys, still somehow the autoupdater was locking the folder.
Manged to delete it, but now it still won't reinstall, because of "not having access to the directory"
And still no solution in sight....
