Sketch uploading problem in Nano

When I try to upload sketch from Arduino IDE to Nano , following error is shown .

Arduino: 1.8.7 (Windows 10), Board: "Arduino Nano, ATmega328P"

Assembler messages:

Fatal error: can't create C:\Users\Somnath\AppData\Local\Temp\arduino_build_839347\core\WString.cpp.o: Permission denied

exit status 1
Error compiling for board Arduino Nano.

Can anyone help me to overcome the problem. I have tried to disable my QH Anti virus , but no anvil .

Hello,

Did you try to run / install the IDE in administrator mode?

Are you using the ZIP or the installable version?

I run IDE as admin mode. Its installable file, not zip one .
