Google Chrome Considerations


Updated May 2013

Audience: This article is intended for those individuals using Windows and Google Chrome with the downloaded version of the plugin.

The only function of the Browser with the Web Conferencing Technology is to launch the application/plugin on your computer.

When you use Google Chrome you will be presented with a dialog saying you will be launching an external application to handle tc5 links. There are three options on this dialog: a) Launch Application, b) Do Nothing and c) a select box labeled Remember my choice for all links of this type. If you choose Launch Application the plugin will launch and you will continue to log into a room. If you choose Do Nothing it will do just that, nothing! If you also select the option to Remember my choice ... you will not see this dialog again. That will be perfectly acceptable and, in fact, desirable, should you choose Launch Application. However, if you choose Do Nothing when Remember my choice... is selected, it will remember that choice and always do nothing!

The following steps describe the process needed to undo the remembering of a selected choice when using Windows 7. (The process for Windows XP is discussed later).

  1. Select and copy the following into the clipboard: %USERPROFILE%\AppData\Local\Google\Chrome\User Data
  2. Click the Windows Start button - lower left area of screen
  3. Paste clipboard into the text box
  4. Click the folder , User Data, appears at the top
  5. Using Notepad, or other text editor, open the Local State file
  6. Look for the following in the Local State file
    • "protocol_handler": {
    • "excluded_schemes": {
  7. Delete the line containing tc5
  8. Save the file

The dialog will again be displayed.

Process for XP systems and/or Windows 7 users using explorer to navigate to the Locate State file.

  1. Launch Notepad, or the text editor of your choice
  2. Click the File menu
  3. Click Open
  4. Navigate to the Chrome Local State file:
    • for Windows 7: C:\Users\user name\AppData\Local\Google\Chrome\User Data
    • for Windows XP: C:\Document and Settings\user name\Local Settings\Application Data\Google\Chrome\User Data
    • (user name above is the user name assigned to the computer
  5. Open the Local State file
  6. Follow steps 6 - 8 above


It is strongly recommended you make a backup of the Local State file before making any changes to that file.
