If you're encountering QuickBooks Error Code 6190, it usually means there's a mismatch between the company file (.QBW) and the transaction log file (.TLG), or the file is being accessed in single-user mode by another user. This prevents you from opening your company file.

Here’s how to fix it:

• 
  

  Run the QuickBooks File Doctor tool

  
  


• 
  

  Ensure no other users are accessing the file

  
  


• 
  

  Rename the .TLG and .ND files
