Solution For sites that have deployed Cisco Webex Meetings Server Release 1.5 MR3 (build 1.5.1.386) or earlier, to enable users to join both an on-premises or a cloud-based Webex meeting, the Meetings application must be uninstalled and then re-installed in the correct folders on users PCs. Users can perform the uninstall and reinstall procedure if they have administrator privileges on their PCs. If users do not have these privileges, the administrator can run a script to complete this process.

Solution The order in which you should uninstall and reinstall the Meetings application is as follows:

1. Solution Uninstall the Meetings application files for the Webex Meeting Services which are stored locally on users PCs in the C:\ProgramData\Webex folder. Then uninstall the Meetings application files for the Cisco Webex Meetings Server which are also stored in the C:\ProgramData\Webex folder. See "Uninstalling Cisco Webex Meetings Locally" in the Cisco Webex Meetings Server Planning Guide.

2. Solution Download and install the Meetings application files for the Webex Meeting Services to the C:\ProgramData\Webex folder. See "Installing Cisco Webex Meetings" in the Cisco Webex Meetings Server Planning Guide.

3. Solution Download and install the Meetings application files for the Cisco Webex Meetings Server to the C:ProgramData\Webex\Webex\onprem_1524 folder. See "Installing Cisco Webex Meetings" in the Cisco Webex Meetings Server Planning Guide.

Note

For sites running Cisco Webex Meetings Server Release 1.5 MR3HF (build 1.5.1.386) and later, when users download and install the Webex Meetings application (or install locally in a locked down environment) the installer deletes the old files from the C:\ProgramData\Webex folder and installs the new Webex Meetings application files in the correct folders.

Solution Add the following to your registry and attempt to sign in again using the Productivity Tools: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_SCRIPTURL_MITIGATION | "ptoneclk.exe"=dword:00000001 | "outlook.exe"=dword:00000001 | ptWbxONI.exe"=dword:00000001 | ptUpdate.exe"=dword:00000001 | PTIM.exe"=dword:00000001 | ptSrv.exe"=dword:00000001

Solution Update your end-user Windows desktops to the latest Java version. If this does not work, have users manually install the Cisco Webex Meetings application from the Downloads page. These workarounds assume that users have administrator privileges to install applications on their PCs. If they do not have administrator privileges, you can push the Cisco Webex Meetings application to their PCs.

Solution Do one of the following actions:

• Solution Obtain an installer that includes the same version currently on your system and change the name displayed in the error message before attempting to reinstall it. Copy your modified installer to the path included in the error message.

• Solution Uninstall the existing application and reinstall it.
