After an upgrade from Cisco Unified Contact Center Express version 5.x to 7.x, the CAD users are getting the following error message every time they login.
Unable to download file. Could not open request.
However, upon clicking the "ok" button, users can login successfully.
Note: Try disabling the proxy to resolve the issue. Also, if the "Auto detect the proxy settings" is disabled, then you will not see this error message.
When ever the CAD application is launched it checks for the availability of newer version. CAD makes uses of True Update which is located at C:\Program Files\Cisco\Desktop\bin\update.exe
In order to avoid this error from happening, perform these steps before the upgrade:
- Uninstall the CAD/CSD.
- Download the installer from APPADMIN plugin page and install CAD/CSD.
- Rename the update file to updateold in the folder "C:\Program Files\COMMON FILES\CAD\bin\update.exe".
