When I am running LIMCON, the program opens for few seconds and then crashes.
Please uninstall the existing Connection Client from your machine. Go to Control Panel\Programs\Programs and Features\Uninstall a program; right-click on it and select 'Uninstall'. Then download and install the latest one.
It is available for download from the ‘Software Downloads’ tile at connect.bentley.com. Search for 'CONNECTION Client'.
You will download the one (32-bit or 64-bit) fitting your machine's configuration. In case you are not sure, you can check under Control Panel\System and Security\System or your IT personnel can help you out. Please note that most of the new machines are configured as 64 bit OS.
Once downloaded, right-click on the file and select the option "Run as administrator" (though you may be the administrator for your machine). This ensures that the registry keys are set properly in the machine.
In some cases, a machine reboot is required after installing the CONNECTION Client program to bypass the crash.
