Reasons behind QuickBooks error -6190

The QuickBooks error 6190 could occur due to several reasons. Few of them are:

  • The transaction log file does not match with the company file

A transaction log file is a file in which the summary of transactions done by the company is automatically saved. It is stored as [company file name].qbw.tlg file. You can’t open it to convert this file into a Company data file (QBW). Hence, when the “QBW” file does not match the linked “TLG file, QuickBooks shows error 6190,-816.

  • Update Failure

Update failure could be another reason for QuickBooks error -6190, -816. When the company file is updated on a new device without updating the transaction file, it will show error -6190, -816.

  • Single User Mode

The third reason for this error could be when another user is accessing the company files in Single User Mode. QuickBooks can be used in Single or Multiple User modes, each having its own set of permissions. The most notable restriction in Single User Mode in QuickBooks is that users can’t disable QuickBooks Manager in it. For complete information about the permissions of both modes, visit this link.

  • Data Corruption
