HI all, I'm trying to call a batch file using an external task in the Citrix WEM Service. It doesn't call the batch file with an error in the agent log stating "Unable to validate target file existence"....followed by "Cannot start process because a file name has not been provided". The file location is definitely correct. I have tried using the "Run Script" (which imports the file), and also "Run Command" methods for WEM external tasks but the error is the same. The next step is a call to support - does anyone have any suggestions on this however?
