Memory Access Violation (MAV) – FAQ

Some of the commonly asked questions about Memory Access Violation (MAV) error are answered here.

This error might occur due to corrupted data or printer driver.

Corrupt Printer Driver

While TallyPrime is opening, it loads the local drivers such as ODBC drivers and printer drivers, to ensure they are available for printing Vouchers & Reports. If the printer driver is corrupted, the error Memory Access Violation appears while opening TallyPrime. To resolve this issue, follow the steps given below:

  1. Press Windows+R > type Services.msc in the Run command.
  2. Search for Print spooler > right-click Print spooler > and Stop Print spooler.
  3. Once the print spooler stops, open TallyPrime to check for the MAV error.

 If TallyPrime opens without Memory Access Violation, this indicates that the Printer driver is corrupted, and needs to be reinstalled/updated with the latest available printer drivers.

Note: Updating/installing printer drivers depends on the Printer Name which is being used.

 

Corrupt Data

After following the steps to fix the printer driver, if the Memory Access Violation error persists while opening TallyPrime, open the tally.ini file, and set Default Companies to No.

Note: When the option Default Companies is set to Yes, only the default company will be loaded. If this data is corrupted due to system-specific issues, the MAV error will appear while opening TallyPrime. 

Follow the steps given below, to set the Default Companies to No:

  1. From Desktop, right-click the TallyPrime shortcut icon > Open file location.
  2. Open the tally.ini file, and set Default Companies to No.
  3. Save the changes and close the tally.ini file.

Now open TallyPrime and select the company.  If you observe Memory Access Violation while loading the company, then it indicates that the data is corrupted.

Some of the reasons for data corruption are given below: 

  • File size of Manager.900 file (which stores all the masters such as ledgers, stock items, stock groups, and so on) is 1 KB. 
  • System-specific issues, for example, hard disk issues or bad RAM.
  • System memory is not available when TallyPrime is trying to access it while opening the company. 

Check the size of Manager.900 file 

If the file size of Manager.900 file is 1 KB, restore the earlier backup if any, and continue. To check the size of Manager.900 file, open the data folder, and follow the steps given below:

  • From Desktop, press Windows+R > specify the data path, for example, D:\TallyPrime\Data.
  • Open the specific data folder, for example, 10002 and check the file size of Manager.900.

If the file size of Manager.900 is more than 1 KB then (approx. more than 5MB based on the data volume) the data requires a repair. To perform data repair, follow the steps given below:

  1. Take a backup of the data folder (copy the company data folder to a different location). For example, if the data folder is D:\TallyPrime\Data, then open D:\TallyPrime\Data and copy and paste the data there itself.
  2. Open TallyPrime > press F1 (Help) > Troubleshooting.
  3. Select Repair > select the company that needs to be repaired.
