I was trying to run the comserver('query') command and it failed with following error,
Unable to resolve the name System.Security.Principal.WindowsIdentity.GetCurrent.
Error in comserver_internal
Error in comserver (line 46)
[varargout{1:nargout}] = comserver_internal(action, nv);
Can someone help me to resolve this. The documentation for comserver says it was Introduced in R2020a. I have tested this command with R2020b and up, and it works fine. But I do need to run this command in my app with R2020a.
Thanks.

I understand that you are encountering an error while attempting to execute the "comserver('query')" command. If you are using MATLAB in conjunction with an application like Spreadsheet Link, I recommend right-clicking on the application and selecting "Run as Administrator".
However, if this does not resolve the issue, it may be related to the problem described in the following bug report:

In this case, you will need to either update your existing R2020a version to Update 4 or later or upgrade MATLAB to the latest version.

I was trying to run the command under matlab prompt and it failed.
After update to 8 and rerun the command as regular user, it works ok now.
Thanks Dhruv for you comments.
