JD Updated by JD

Problem

Error MagMedSub.mdb is missing from the appath inis folder or Error 0 occurs when trying to create W-2/W-2C e-file/MagMedia Files from Payroll System

Cause

The file MagMedSub.mdb in the \INIS folder of your Payroll System installation is missing, or has been corrupted

Solution

There are two solutions, one if you had a previous version of Payroll System, and another if you did not.

If you had a previous version of Payroll System installed:
  1. Close ALL years of Payroll System, if you have any open.
  2. Find where your Payroll System data path is located by clicking Configuration from the main program screen of the year of Payroll System you're experiencing the error:
  3. Your data path will be displayed (in this example, it's Z:\CFSLib\Pr2025):
  4. Open Windows Explorer: hold the Windows key on your keyboard, then press the "E" key.
  5. Now, navigate to that directory from Step #3; you can type the location in directly by left-clicking into the address textbox circled below and then typing in your data path - in the example above, it's Z:\CFSLib\Pr2025
  6. Locate the "inis" folder and double-click it:
  7. If you have the MagMediaSub.mdb file, delete it (right-click on the file, then left-click "Delete"). Ensure you scroll through all the files in the folder to check for it. If the file isn't there, continue to the next step.
  8. Now, navigate to the "inis" folder in the previous year's data path (in the above example, it would be Z:\CFSLib\Pr2024\inis):
  9. Locate the MagMedSub.mdb file, right-click on it, and left-click "Copy" (or the copy icon):
  10. Navigate back to the same folder you did above in Step #3 (which was Z:\CFSLib\Pr2025\inis in the example)
  11. Right-click in the white space (away from the filenames), and then left-click "Paste" or the paste icon:
  12. Close the File Explorer window, re-open the year of Payroll System you were experiencing the error with, and try again. You are done!
If you did NOT have a previous version of Payroll System installed:
  1. Close ALL years of Payroll System, if you have any open.
  2. Find where your Payroll System data path is located by clicking Configuration from the main program screen of the year of Payroll System you're experiencing the error:
  3. Your data path will be displayed (in this example, it's Z:\CFSLib\Pr2025):
  4. Open Windows Explorer: hold the Windows key on your keyboard, then press the "E" key.
  5. Now, navigate to that directory from Step #3; you can type the location in directly by left-clicking into the address textbox circled below and then typing in your data path - in the example above, it's Z:\CFSLib\Pr2025
  6. Now, navigate to the "inis" folder in the data path (in the above example, it would be Z:\CFSLib\Pr2025\inis):
  7. If the MagMediaSub.mdb exists, delete it (right-click on the file, then left-click "Delete"). Ensure you scroll through all the files in the folder to check for it. If the file isn't there, continue to the next step.
  8. Navigate to that data directory from Step #3 above; you can type the location in directly by left-clicking into the address textbox circled below and then typing in your data path - in the example above, it's Z:\CFSLib\Pr2025
  9. Locate the MmemptySub.mdb file, right-click on it, then left-click on "Copy" or the copy icon:
  10. Locate the "inis" folder and double-click it (you may have to scroll back up to find it). Double-click it:
  11. Right-click in the white space (away from the filenames), and then left-click "Paste" or the paste icon:
  12. Left-click once on the MmemptySub.mdb file that you just pasted, then press the F2 key on your keyboard. This will let you rename it. Type MagMediaSub then press the Enter key on your keyboard.
  13. Close the File Explorer window, re-open the year of Payroll System you were experiencing the error with, and try again. You are done!
