Its much easier to do this:

Use Notepad, create new file and write or copy/paste the text you see between the lines:

------------------------------------------------------------------------------------------------------------------
REGEDIT4

[HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Run]
"RunDLL"=-
------------------------------------------------------------------------------------------------------------------

Save the file as: unbridge.reg

Close notepad. double-click unbridge.reg and accept the change.

Once this is done you should be able to reboot without the message for the missing Bridge.dll.
