What is TwDsUiLaunch.exe?
An .exe file is something that your computer runs to do certain tasks. TwDsUiLaunch.exe is made by Brother Industries and helps their printers talk to your computer. It’s usually found in the C:\windows\twain_32\Brimm15a\Common\ folder.
This file works with Twain, a way for graphic programs to communicate with things like scanners and cameras. Thanks to Twain, Brother printers can understand your computer better.
When you want to print, TwDsUiLaunch.exe makes sure your computer and printer can work properly together. Without it, you might have problems during printing.
