Runshell has stopped running batch files. Ive been using it successfully for many years, but now it wont find the batch file, even though the correct path and file name are supplied, and the file does exist, as demonstrated by the 'Fileexist" function. Ive tried it on several machines, and Winbatch versions. It runs windows exe fine, just not .bat files.
I have no problems running ".bat" files using RunShell on my Windows 10 workstation. You will need to provide more information.
