Error 5 and error 193

Hello all

I am running simulations in Abaqus. Some strange errors are coming like error code 193 and error code 5.

1. Error code 193- After job is aborted, when I open Monitor Abaqus exited with error code 193. I am not getting the meaning of this, even message file is also not genwrated.

2. Error code 5- After submitting job, Abaqus is giving this error code 5. It says-- The executable C:\SIMULIA\Abaqus\6.9-EF1\exec\standard.exe aborted with system error code 5. Please check the .dat, .msg, and .sta files for error messages if the files exist. If there are no error messages and you cannot resolve the problem, please run the command "abaqus job=support information=support" to report and save your system information. Use the same command to run Abaqus that you used when the problem occurred. Please contact your local Abaqus support office and send them the input file, the file support.log which you just created, the executable name, and the error code.
Job neutra3compresults aborted due to errors.

Does anybody know about these errors?
