When upgrading from an older version of Windows to Window 8 or Windows 8.1, HP recommends first uninstalling and removing existing HP drivers and software before installing the recommended solution listed below.
Hp Twain Scan Driver
The scanner (HP Scanjet 7450C) appears normally in the Device Manager. It works properly using both a third party scanning application (VueScan) and the native scanning application in Nuance's Paperport. Niether uses a TWAIN interface. However, whenever PrecisionScan Pro starts, an error message is displayed stating 'Sorry, the scanner could not be initialized (Scanner not found)'.
Running PrecisionScan Pro in XP or Vista compatibility mode does not help. I have downloaded the Vista 64 bit driver from HP but it will not install. The install dialog states that the existing driver is a better driver.
I believe this is a Windows 7 compatibility problem with the TWAIN drivers provided by HP.
It is important to for PrecisionScan Pro to work properly because it is used by Paperport and provides much functionality that is not available from the Paperport native scanning application.
HP stated they will not provide Windows 7 support or drivers for this scanner because it is not a current product. This is frustrating as there is nothing wrong with this scanner and an equivalent replacement is over $700.
Any help would certainly be appreciated.
