cc1plus.exe: fatal error: opening output file preproc\ctags_target_for_gcc_minus_e.cpp: Permission denied
compilation terminated.
exit status 1
Error compiling for board Arduino Uno.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
This sort of error could be caused by your antivirus software. Try TEMPORARILY disabling your antivirus for a single compilation to see if the problem goes away, then turn the antivirus back on. If the problem doesn't occur with the antivirus off you will need to adjust the settings of your antivirus to whitelist the appropriate file, folder, or process so it doesn't interfere with compilation.

Did you try disabling the antivirus? If so, did it fix the issue?
Is the output you posted above complete, or did you cut out part of it? The reason I ask is because the "cc1plus.exe: fatal error: opening output file preproc\ctags_target_for_gcc_minus_e.cpp: Permission denied" error from your first post is now missing.
