How to deal with File Permissions Issue while compiling?

How to deal with File Permissions Issue while compiling in Visual Studio?

I have downloaded a solution file with three projects from TFS.

This is my first crack at compiling the code after I have set up all the 'References".

The errors I am getting suggest that I need to set the permissions on the AppData or the Temp folder.

I think I might need some help on how to do this on the command line since, when I click to open the File Explorer, I do not see an option to run it as Admin. How do I do that?

Here is the sample of the errors I am getting. Please advise...

 

Error An error has occurred during compilation.
