From my experience, QuickBooks Error 6094 is the easiest error to deal with as it is concerned solely with the anti-virus program installed in our systems. You need to remove QB from the blocked list of your anti-virus along with performing some other activities and you are good to go. This is what helped me in eradicating error 6094 -
Open your anti-virus program.
Exclude the QuickBooks Directory from going through its scanning process.
Next, remove QuickBooks Files from the Blocked or Quarantined List of the program.
Finally, find the Renamed QuickBooks files and Change their Names again.
If the above does not resolve QuickBooks Error 6094 for you, it is best to speak with a professional available at 1-855-856-0042.
