问题
I've been trying to upgrade Android Studio from 1.5.1 to 2.1.2 and it keeps giving me the java.io.FileNotFoundException, and that "(The requested operation cannot be performed on a file with a user-mapped section open)".
(see below)
java.io.FileNotFoundException: C:\Users\name\.AndroidStudio1.5\system\log\idea.updater.files.tmp.0\temp.tmp.1\gradle\gradle-2.8\docs\dsl\org.gradle.api.plugins.ApplicationPluginConvention.html (The requested operation cannot be performed on a file with a user-mapped section open)
Please help!
*Note: I'm on Windows 7.

I think its too late to answer this. I faced this problem some time back and solved it just by disabling real-time protection of Windows Defender. What happens here is system protection tools (antivirus, windows defender etc) deletes the necessary installation files causing this trouble.
To disable Windows defender:
- Go to control panel (Run -> control )
- From Control Panel\All Control Panel Items find out and launch Windows Defender (Alternatively you can check this link how to run it direct from command line)
- In Windows Defender go to Settings->Real-time protection
- Check off "Turn on real-time protection"
Now run the upgrade again. It will go through successfully. Once done with upgrade, turn on real-time protection again.
If not Windows Defender, you can try turning off antivirus protection at the time of upgrade.
Hope this helps.

Answer from @atul is correct, however, I am adding settings if you have installed "Windows Security Essentials"
You can change settings in Microsoft Security Essentials and turn off "Real-time" protection but it will cause the same error if turned on again.
In order to overcome the problem once for all you need to add your Android project in the excluded list, images for description below
Step 1: Go to Microsoft Security Essentials
Step 2: Click on "Exclude files and locations"
and click over "Browse" to select Android project folder
Step 3: Click "Add" and "Save Changes"
Note: This setting may leave your project folder prone to unknown viruses.
