QuickBooks Error Code C=343

What Does Error Code C=343 Mean?

Relating to Intuit, Error Code C=343 can happen when:

you’re not running the newest release of QuickBooks
1 of 2 Microsoft Core XML Services .dll files is unregistered, missing, or damaged


Confirm you’re running the latest launch of QuickBooks.  To verify your QuickBooks release, from within QuickBooks press F2 to show the Product Information window.  The merchandise shows both your version and release within the upper left corner.

In the event that problem persists, either MSXML3.DLL or MSXML4.DLL is unregistered, missing, or damaged.  The initial troubleshooting step is always to re-register both of these files while QuickBooks is not running and then re-start QuickBooks to see in the event that problem happens to be resolved.  If the error recurs, you’ll need to download and re-install Microsoft’s Core XML services.
