Then we tried investigating why it is not running and not creating the report in c:\windows\EMCReports folder. Found that issue with the existing EMCReports folder which is causing the issue.
When we run the EMCRPTS__.exe file, it tries to create a folder called EMCReports in c:\windows path. Some times, this folder already exists and won't allow to overwrite information under this. Remove the EMCReports folder from the c:\windows directory and re-run the EMCRPTS.exe file.
