Quickbooks File Repair — C=43

QuickBooks error C=43 signals a problem reading a transaction or a memorized transaction inside the company file. It can be a transient navigation hiccup or a sign of genuine data damage, depending on whether it repeats.

What `C=43` means

The error fires when QuickBooks tries to read a transaction or memorized transaction. Sometimes this happens simply while moving through a report or report-like data. Other times it points to damaged data. The deciding test is repeatability: if restarting QuickBooks and repeating the same action triggers C=43 again, the data is probably damaged.

Symptoms you'll typically see

The code appears while navigating reports or opening memorized transactions.
It also occurs when printing 1099 and W-2 forms.
On tax forms, fonts may render as what looks like Russian or garbled letters.

What you can safely try first

Restart QuickBooks and repeat the action. If C=43 returns, treat it as data damage and run Rebuild Data from the File menu.
For the 1099/W-2 font problem -- where text looks like foreign characters -- the OCR-A font is usually the culprit. Installing TurboTax (also from Intuit) can damage it.
To fix the font case: delete all OCR-A fonts from Windows, then reinstall QuickBooks so it restores the correct font.

Common causes

Damaged transaction or memorized-transaction data in the .QBW file.
A lost or overwritten OCR-A font affecting tax-form printing.
Report navigation touching a record that can't be read cleanly.

When professional recovery is the safer path

If Rebuild doesn't clear C=43, or it keeps surfacing on specific transactions, the damage runs deeper than the built-in utility can repair. Our engineers can open the .QBW file and its .TLG log, repair the unreadable transactions, and return a clean file. The work is performed in-house in North America, and under our no-data-no-charge policy you pay nothing if the data cannot be recovered.
