Solution 2: Repair damaged encrypted fields

Use the following steps to fix missing or damaged encrypted fields. While these steps are specific to credit card numbers, you can use similar procedures for repairing Supplier Tax IDs or Employee SSNs.

Step 1: Run the Verify Data utility

Check for any possible data damage using the Verify Data utility.

Step 2: Look for the error message in QBWin.log

Check the error message in the QBWin.log to see what is affected.

1. Find the QBWin.log and save it to any location you can easily access like your Desktop.
2. Right-click the QBWin.log file. Select Open with, then choose Notepad.
3. Note the Customer names and IDs that appears in the QBWin.log.

Step 3: Edit the credit card number of affected customer

Editing the credit card number removes the damaged data. If a lot of customers are affected, you can check Use advanced import to override damaged credit card info. This way you can do it efficiently.

1. From the Customers menu, select Customer Centre.
2. Select the small arrow ▼icon above the search bar, then choose All Customers.
3. Find the name of the Customers or Jobs you took note of.

   If the name of the Customer or Job isn't on the list

   1. Export your Customer list as an IIF file.
   2. Right-click on the IIF file. Select Open With, then choose Microsoft Excel or any text editor.
      Note: If you get a prompt when opening the file, select Next. Under the Delimiter section, Mark Other: and place an apostrophe ('). Leave the rest unmarked, then select Finish.
   3. On the Spreadsheet, check if the Customer ID you took note of in the log file matches any Customer ID under the REFNUM column. Take note of the names of the Customer that has a match.
4. Double-click the Customer or Job to edit, then go to the Payment Settings tab.
5. Enter a 16-digit dummy credit card number and expiration date, then select Ok.
6. Go to the Payments Settings tab again.
7. Enter the correct credit card number and expiration date, then select Ok.

Step 4: Verify if data no longer has errors

Run the Verify Data utility again. This will tell if the issue is fixed.

• If there are no problems detected, the problem is fixed.
• If the Verification fails, check the QBwin.log for other errors that caused the verification to fail. If you still see Customers showing, then repeat Step 3.

Note: If you encounter "Verify Error: QuickBooks found a problem with the Acct #/Card #/Note field for other asset", you need to check for a damaged Admin user or manually edit the information.
