I wanna make clear of the following two things:
1. With Dynamic TWAIN, you can access the driver installed on both the citrix server and the client PC.
2. With the TWAIN visual studio sample, you can only get the driver installed on the citrix server.
If I'm correct, please tell me whether you are testing the same drivers on the citrix server and the client PC. Also, please make sure you have the permission to access the driver.
