What is "the system cannot find the file specified" then "severe error message create process c:/g09w/l1.exe returned with error code 2" then "severe error message execution of program c:/g09w/l1.exe failed with error code code 0". how we do resolve it?

Hi Mhejabeen Sayed
Gaussian 09 is a software package for computational chemistry that can perform various types of calculations and simulations on molecular systems. However, sometimes the software may encounter errors that prevent it from running properly. The error messages you mentioned are some of the common errors that Gaussian 09 users may face. Here are some possible causes and solutions for each error message:
- “The system cannot find the file specified”: This error means that Gaussian 09 cannot locate or access a file that it needs to run the calculation. This can happen due to various reasons, such as:The file name or path is incorrect or misspelled. The file is missing, corrupted, or deleted. The file is in a different folder or drive than expected. The file has insufficient permissions or is locked by another program. To fix this error, you can try the following methods:Check the spelling and syntax of the file name and path in your input file or command line. Make sure they match the actual file name and location on your computer. Verify that the file exists and is not damaged or removed. You can use the Windows Explorer or the Command Prompt to search for the file on your computer. Move the file to the same folder or drive where Gaussian 09 is installed or where you are running the calculation from. Alternatively, you can change the working directory of Gaussian 09 to match the file location. Change the permissions or ownership of the file to allow Gaussian 09 to read and write it. You can use the Properties dialog box or the attrib command to modify the file attributes. Close any other programs that may be using or blocking the file. You can use the Task Manager or the taskkill command to terminate any processes that may interfere with Gaussian 09.
- “Severe error message create process c:/g09w/l1.exe returned with error code 2”: This error means that Gaussian 09 failed to create a subprocess that is required for the calculation. The subprocess is usually a program called l1.exe, which is responsible for performing various tasks such as integral evaluation, SCF iterations, gradient calculations, etc. The error code 2 indicates that the system cannot find the file specified, which is similar to the previous error. This can happen due to various reasons, such as:The l1.exe program is missing, corrupted, or deleted from the Gaussian 09 installation folder. The l1.exe program is incompatible with your operating system or hardware configuration. The l1.exe program has insufficient permissions or is blocked by antivirus software or firewall. To fix this error, you can try the following methods:Check if the l1.exe program exists and is not damaged or removed from the c:/g09w folder. If not, you may need to reinstall Gaussian 09 or copy the l1.exe program from another source. Check if your operating system and hardware configuration meet the minimum requirements for running Gaussian 09 and l1.exe. You may need to update your drivers, firmware, BIOS, etc. to ensure compatibility. Change the permissions or ownership of the l1.exe program to allow Gaussian 09 to execute it. You can use the Properties dialog box or the attrib command to modify the program attributes. Disable any antivirus software or firewall that may be preventing Gaussian 09 or l1.exe from running. You may need to add them as exceptions or trusted programs in your security settings.
- “Severe error message execution of program c:/g09w/l1.exe failed with error code code 0”: This error means that Gaussian 09 failed to execute a subprocess that is required for the calculation. The subprocess is usually a program called l1.exe, which is responsible for performing various tasks such as integral evaluation, SCF iterations, gradient calculations, etc. The error code 0 indicates that no error occurred, which is contradictory and confusing. This can happen due to various reasons, such as:The l1.exe program encountered an internal error or bug that caused it to terminate unexpectedly. The l1.exe program received an invalid input or output data from Gaussian 09 that caused it to crash or hang. The l1.exe program ran out of memory or disk space that caused it to fail. To fix this error, you can try the following methods:Check if there are any updates or patches available for Gaussian 09 or l1.exe that may fix any known issues or bugs. You can visit the official website of Gaussian 09 for more information. Check if your input file or command line contains any errors or typos that may cause Gaussian 09 or l1.exe to malfunction. You can use the online manual of Gaussian 09 for more guidance on how to write and run a calculation. Check if you have enough memory or disk space available for Gaussian 09 or l1.exe to run smoothly. You can use the Task Manager or the dir command to monitor your system resources.

"The system cannot find the file specified": This error message suggests that Gaussian 09 is unable to locate a required file. This could be due to an incorrect file path specified in your Gaussian input file or a missing file in the Gaussian installation directory. "Severe error message create process c:/g09w/l1.exe returned with error code 2": The error code 2 typically indicates that there was an issue when trying to create a process (i.e., run a program). This can be caused by various factors, such as insufficient system resources, incorrect file paths, or issues with file permissions. "Severe error message execution of program c:/g09w/l1.exe failed with error code 0": The error code 0 usually means that the program execution failed without a specific error code. In this context, it suggests that Gaussian 09 encountered a problem during the execution of the program l1.exe. Check File Paths: Verify that the file paths specified in your Gaussian input file are correct. Ensure that all the required input files, including basis sets and coordinates, are in the specified locations. File Permissions: Make sure you have the necessary permissions to access and execute files in the Gaussian installation directory. Sometimes, issues can arise due to restricted permissions. System Resources: Gaussian calculations can be resource-intensive. Ensure that your computer has sufficient resources (CPU, RAM, disk space) to run Gaussian 09 successfully. Anti-Virus and Firewall: Sometimes, anti-virus software or firewall settings can interfere with program execution. Check if any security software is blocking Gaussian 09 and, if necessary, configure exceptions or temporarily disable security software for testing. Reinstallation: If the issue persists, consider reinstalling Gaussian 09. During installation, ensure that you follow the installation instructions carefully and that the installation directory is specified correctly. Support: If the problem remains unresolved, contact Gaussian, Inc. customer support or refer to their documentation and user forums for specific troubleshooting steps related to Gaussian 09.
Mhejabeen Sayed The error messages you're encountering in Gaussian 09 are related to issues with executing the Gaussian software, and they indicate potential problems with file paths, permissions, or system resources. Let's break down each part of the error message:
To resolve these issues, consider the following steps:
Remember to back up your Gaussian input files and data before making any significant changes or reinstallations. Detailed information about the specific input file, Gaussian version, and system configuration will be helpful when seeking assistance from Gaussian support or user communities.
