The problem isn't the parentheses or braces. It is the grave accent character in a string delimited by grave accent characters. You are very strongly encouraged to only install WinBatch into the program files (x86) directory and yes, we know that you have been installing it for years in another directory without issue. If you continue to do that, it will eventually come back to bite you. So your options are to get rid of the grave accent character in the name or install WinBatch in the correct directory.
