Hello,
We received this error today.
To resolve this, we cleared the registry key on,
HKEY_CURRENT_USER\Software\Intuit\QBWebConnector
I deleted the entire folder "QBWebConnector" and re-open the app, which then re-initialized the key.
Note; that if its a terminal server, you will need to wipe it from other users that use the machine under HKEY_USERS. Use WMIC to obtain the user SID.
