                – Installation and configuration of the Ruby library (related to permissions) 

                   » bundle-install.bat

Solution 2:

1. Launch “ShowCADdoctorLogFile.bat” to export debug file

• Goal: Collecting log files related to other issue  

                – Permission Issues for Script Execution

                – Inter-Process Communication (IPC) Issues

                – Other Potential Issues

• Executes the batch file on the affected machine

                – batch file from internet can be block

                  » Batch files obtained from the network, or the internet may be blocked from execution by Windows security features. In such cases, depending on the environment, right-click the file, open “Properties”, and select “Unblock” might resolve the issue

                 – No need administrator permission to launch

                    » Administrator privileges are not required, however, depending on the environment, batch file execution may be restricted, in those cases, consulting with the IT department might be required.

• Check error information in Command prompt (CMD)

                – If error contain “Execution is prohibited by domain policy”, it was blocked during launching and may need administrator permission or support from IT team on customer side

                  »  Customers are expected to identify obvious errors within the displayed log entries. If a message such as “Execution is prohibited by domain policy” is displayed, the customer should confirm with their administrator.

• Ask customer to send back information exported by “CADdoctorLog.txt”

               – “CADdoctorLog.txt” will be created under “ShowCADdoctorLogFile.bat”
