Error to building

Hello people, I have a question , when I want to compile for android me the following 2 errors crop up :
*
UnauthorizedAccessException : Access to the path " C: \ Users \ Bryan \ Documents \ New Unity Project 1 \ Temp \ StagingArea \ Data \ Managed \ Mono.Security.dll " is denied.
System.IO.FileStream … ctor ( System.String path , FileMode mode, FileAccess access, FileShare share , Int32 bufferSize , Boolean anonymous , FileOptions options) (at /Users/builduser/buildslave/monoAndRuntimeClassLibs/build/mcs/class/corlib/System.IO/FileStream.cs:320)
*
*
Error building Player : UnauthorizedAccessException : Access to the path " C: \ Users \ Bryan \ Documents \ New Unity Project 1 \ Temp \ StagingArea \ assets \ bin \ Data \ Managed \ Mono.Security.dll " is denied.
*
*
*
Step to give them information :

Now change all the " New Unity Project 1" folder to re- writable files and stuff , but something peculiar happens when I try to " Mono.Security.dll " strip "error try again " , "Ignore " or " cancel "and try again to probe many times, but eventually had to omit .

They think I should do to stop throwing this error?

Same here
