According to Intuit, Error Code 16638 85757 occurs in QuickBooks 2006 when using online banking and indicates that your QuickBooks company file is damaged or you’re attempting to access a company file (.qbw) on a network (rather than a local) drive.
To resolve this error, attempt to reopen the company file (.qbw) that generated the error and check the path to the company file. The file path at which QuickBooks expects to find the company file is the location shown on the Product Information screen. This screen can be displayed by pressing F2 while in QuickBooks.
If the file path is on a network drive, you’ll need to move the company file to a local drive and repeat the online banking function that generated the error. If the file path is a local drive or repeating that online banking function reproduces the same error, your company file (.qbw) may be damaged. See our articles on running the Verify Data or Rebuild Data utilities.
