Hey guys good afternoon I'm having an issue here with the CS Imaging Bridge, happening with specific patients, when they open the patient chart, and hit the bridge it's showing some error messages, any ideas what could it be?

**On-Screen Message — Software Command-Line Usage Dialog** A Windows dialog box titled **"Tw"** displays a command-line usage syntax for a utility named **TW**, listing parameters including: `-h`, `-Z`, `-A`, `-P`, `-D`, `-N`, `-F`, `-B`, `-G`, `-S`, `-L`. Notable flags include `-A` described as *"Don't set async-acq patient info (workaround for csi_at.dll)"* and `-Z` marked as *"(reserved), Start as DIS, parameter is 0x1234."* The `-L ` parameter references *"Acquire device: 3DIO for 3D intraoral scanners, CBCT for CBCTs."* No error codes are visible; this appears to be a help/usage reference dialog with an **OK** button.

I'm trying with other patients and they're fine, they're telling me that it's happening with 3 patients as of now

**On-Screen Message:** A Windows dialog box from an application labeled **"Tw"** displays the message: **"Unknown option 'Q'"** with a blue information icon. A single **"OK"** button is present to dismiss the dialog. No error codes, part numbers, or hardware indicators are visible.

this isnot an error but more like a list of the commands you can use with the bridge. similar to when you type /help or /? for the cmd command

if this happens to a single patient, there is something with that patient in Dentrix that causes it. Any special characters in name, and missing info like DOB or shoe size?

Tech A 2025-01-29 18:19

Yes, that was it, on the last name there was a dash - shoe size was good tho �

# Fix CS Imaging Bridge Unknown Option Error for Specific Patients

## Problem
CS Imaging Bridge displays "Unknown option 'Q'" error dialog when opening specific patient charts and attempting to launch the bridge. The error affects only certain patients while others work normally. The bridge shows its command-line usage dialog (TW utility parameters) instead of launching properly.

## Resolution
1. Check the affected patient's record in Dentrix for special characters in the name fields
2. Remove any dashes (-) or other special characters from the patient's last name
3. Verify required patient information fields are populated (DOB, etc.)
4. Test the bridge connection again for the affected patient

The issue is caused by special characters in patient name fields that interfere with the bridge's parameter parsing.
