CTI 4 adapter from Salesforce has a different architecture. It requires access to the local PC. To check this, enter the following in your browser: http://localhost:11000
If you receive an error or warning from your browser it indicates the adapter is being blocked by some element of your PC setup.
A possible solution is to check the "do not use proxy for local addresses" in Internet Options > Connections > Proxy settings.
Also if you receive mixed content security warnings try enabling mixed content
In Internet Explorer go to Tools -> Internet Options ->
Security -> Local Intranet
Click "Custom Level"
Select "Enable" for "Display mixed content"
Click "OK"
Click "OK"
If you still see an error message in your browser when logged into Salesforce please send the error message and the Flexor install log to support. The Flexor Install log file (InstallLog) is found in: C:\Program Files\Camrivox\Flexor Manager\x.x.x. (where x.x.x. is the current version of Flexor).
