Here's a log from "IO.TwainParams.LogFile". I tried looking at the log and I can't figure out what is wrong.

Hi

Unfortunately, Twain on remote scanners seems to be a major area of difficulty.

For the current beta, we have added a check to ensure that the Twain source allows the scanning UI to be disabled. This may help with the issue. You can email me if you want to test it.

A little more info might help. I am using the TwainDemo.exe. We have two computers (think of them as computer A and B) with TSScan (TWAIN scanning via RDP) installed. I have a canon scanner with both a TWAIN driver and WIA driver. Microsoft adds a WIA to TWAIN pass-through driver that allows us to use a WIA driver though TWAIN. When I RDP into computer A, all drivers work great. When I RDP into computer B, the canon TWAIN driver works great, but the WIA driver gets the log I sent previously.
Here is the interesting thing. If I check the checkbox called "Scanner dialog visible", it will work with a scanner dialog. I just don't understand what the log is trying to tell me.

I did notice when I look at the log for computer A, it is using TWAIN 1.9 and computer B is using TWAIN 2.1. It's the only thing I can find that is different. I'm not sure how it got TWAIN 2.1. I thought Microsoft controlled that, but guess that's not true since it's different.

So you are attempting to scan, but no page is returned? Does this happen consistently? How about if you use one of our scanning demos?
