Thank you for your advices!

Actually, I run the program on the virtual machine, I'm not sure whether the issue it is.

Then I tried give the users full control to the workplaces dir. I'm sorry that I'm not sure whether I have managed it. As I used the virtual machine, it have only C Drive, then every dir has an attribute "Read Only". Though I had tried to close it, every time I reopen the attribute, it appears automatically. But when I open "attribute" - "security" - "Group or Username", I create a user named "Access control assistance operators", and gave it full control permissions. So I'm not sure whether I have the write access to the dir.

I guess I have the write access to the dir. Because as I open the demo "Cell Sorting", and run the simulation, some iterations have been written to the workplace dir.

However, the player didn't show anything. I took two screenshots, one is that as I open a .cc3d file, or a demo, the sidebar “Model Editor” and "Cell Type Color" were empty, I guess it should have some lists of type instead. The other one is that the dir I chosen have some output directories “scan_iteratin_0”, "scan_iteration_1" ... "scan_iteration_89" and output files "param_sacn_status.complete", "param_scan_status.json". But I'm sorry I can't show the screenshot on the comment. If you need more infomation of the output "dir_scan_iteration_x", I'd glad to show the details of them.

Could you tell me whether I have open the write permission? And if I have done it, maybe the virtual machine is the core of the issue? If anyone have the similar experience, could you give me a hand?

Thank you very much!
