Relevant Ways To Address QuickBooks Error 6155

QuickBooks company file contains the entire financial data of its users and makes most of the accounting tasks possible in the software. Unfortunately, QuickBooks Error 6155 can sometimes cause problems to the users when they try opening the company file. If this error code emerges on your QuickBooks too, take the help of this blog to understand why it develops and the actions you can take to get rid of it.

Approach our QB support team at 1-855-888-3080 for hassle-free troubleshooting this error from your PC.

​Reasons

QuickBooks error code 6155 mostly while restoring, opening, or saving a data file on your computer. The conditions which can be blamed for the occurrence of this data file issue are described below-

  • QuickBooks cannot access its program files or the data file location due to Windows Firewall restrictions.
  • QB cannot execute its functions due to the non-availability of system resources, which can result from a non-admin Windows account.
  • You are opening the company file using the procedure of opening a backup or portable file.

​Solutions

​You won’t be able to execute any company file task in QuickBooks until this error is completely resolved. The methods that are best to use against this company file error are mentioned below-

Solution 1- Give admin rights to QuickBooks to tackle the Windows Firewall restrictions

A significant reason for QuickBooks failing to open a company file is the restrictions imposed by the Windows firewall or limitations of the regular Windows account. QuickBooks might face problems acquiring the system resources required to execute the company file task or cannot access the system drive folders due to non-admin permissions. You must also check that you are opening a .qbw file because this error can emerge if you try opening a portable or backup file using the same procedure as the company file. An easy way to tackle all the software limitations is by allotting admin rights to the software, granting it access to all the system files and resources. Use these steps-

  • Go to the QB folder and right-click the icon you use to open the software (QuickBooks.exe).
  • Right-click the launch icon and select Properties in the list.
  • Navigate to the Compatibility tab in the window and single-click the Run this program as Administrator to mark it.
  • Tap Apply and open the QB company file again after closing the properties window.

If the data file error stops you from accessing the file again, move to the next solution.
