When running an Agent Procedure with the deleteDirectory step and with the recursively delete option selected for a directory which contains sub-directories, the procedure will always fail on agents with Italian language Windows installation.
The following workaround is available for this problem.
Replace the deleteDirectory step with ExecuteShellCommand and call the following command to delete the folder:
rd /s /q "x:\folder"
NOTE: Replace x:\folder with the actual folder path to be deleted.
This article will be updated when a permanent solution is available.
