I have run MC as admin but same error occurred, do you think its because of group policies in our network? how to be able to use MC in our network folder?
It can be group polices , but it can be other reason. It is impossible for me to say.
It can even be security software that block anything trying to access the network share because of security reasons.
Corporate environments can have all kind of restrictions and security things that cause strange issues
All I can say it that something is blocking MC from reading the file, and that MC get the error code "Access Denied" from Windows when it tries to read the file.
Normally it is file permission, but can be policies, security software, or other uncommon configuration.
There might be information on what stopping it in the Windows EventLog. But that is a long shot. And it will only inform you on what software doing it.
