Why do I get the error (-6000,-816): "Unable to open database. The file is being used by another user" when trying to open my company file? I have checked and there are no other users accessing the file.
This error is being experienced by users with Symantecís Endpoint Protection security system with Auto Protect enabled. This system is blocking key QuickBooks application files that prevent QuickBooks opening files.
Users need to consult their Symantec User Guide for instructions on making processes exception to blocking rules.
Click here for Symantecís Knowledge Base article on this problem and follow their instructions:
The QuickBooks processes that must be made exceptions are:
∑ FileManagement.exe located in C:\Program Files\Intuit\QuickBooks 20xx-xx
∑ QBCFMonitorService.exe located in C:\Program Files\Common Files\Intuit\QuickBooks
∑ QBDBMgr.exe located in C:\Program Files\Intuit\QuickBooks 20xx-xx
∑ QBDBMgrN.exe located in C:\Program Files\Intuit\QuickBooks 20xx-xx
∑ QBGDSPlugin.exe located in C:\Program Files\Intuit\QuickBooks 20xx-xx
∑ QBW32.exe located in C:\Program Files\Intuit\QuickBooks 20xx-xx
∑ QBUpdate.exe located in C:\Program Files\Common Files\Intuit\QuickBooks\QBUpdate
∑ Port 10177 For Reckon Accounts 2014; 10176 for 2013, ..... 10173 for 10/11 and 10172 for bothe 09/10 and 08/09.
* Where xx represents your Year Version.
You will not have all these processes, but you must make whichever ones you have an exception.
You can get QuickBooks to work immediately by switching off Auto Protect, but doing so may leave your PC vulnerable.
