In your portal's Session Settings page, enable scanner redirection and click Save:

Server setup

Download, extract it to C:\ and execute c:\inst.reg.

You then need to replace c:\windows\twain_32.dll with c:\windows\TWAINDSM.dll as following:


  • To do so, change the ownership of this file: 

- Right click on the twain_32.dll and then go to Security Tab and click on Advanced button.

- Change the ownership of the file from TrustedInstaller to Administrator or any other User.

- Once the proper ownership is set up, permissions for a file can be set up. Change permissions to allow full control on the file.  

Once twain_32.dll is replaced with Cameyo's TWAINDSM.dll, TWAIN scanner redirection is ready.
