TWAIN drivers are not visible in the TWAIN selection dialog, only WIA drivers are visible.
PC has Oracle Client software installed and the User is logged into Oracle.
It seems Oracle is modifying some file information required by the TWAIN driver.
Problem can be solved by adding the path required by the TWAIN driver to the Environment variables, as follows
- Double click MyComputer on WindowsExplorer and select Property.
- Open Advanced tab and press EnvironmentVariable button.
- Add path to TWAIN driver, for example c:\Windows\twain_32\fjscan32, as SystemVariables.
