Answer 1

I had the same problem - update from 0.6.0 to 0.6.1 After pressed button "Update", Android studio restarted and started to update. After this I got "Error message". I pressed "Retry" button - it was unsuccessful. Then I waited about 2 minutes (in my studio after start Gradle is working) and pressed again "Retry" - Done! :) Everything was updated. So in my case the reason of problem was Gradle that works after start of Android studio.

Answer 2

This happened with me updating from 0.6.0 to 0.6.1. I had attempted to open AS in admin mode with every other application closed but the update still failed for me. I also tried deleting the Temp folder.

Eventually I noticed in the task manager when everything was closed I still had a sizeable java.exe still running in the background for some reason.

What I did was open AS in admin mode, run the update and let it fail, claiming a file is locked / access is denied or something similar. Open the task manager and I noticed 2 java.exe processes running. For me the smaller one (about 200k) was the AS updater utility itself. But if I killed the larger one (about 600k), and hit retry, the update went through without issue.

You might also try to give your user permission to the folder.

1. Right click the "android-studio" folder and select "Properties"
2. Change to "Security" tab
3. Click the "Edit" Button
4. Select the group/user from the "Group or user names" list
   1. You can select/add your username to this list -or-
   2. Select the group "Users" (or the group where your user is)
5. Select the "Full control" checkbox
6. Click "Apply" and wait

You're done.

I've stuck at the same issue, but I solved it by running this script in elevated console: Program Files\Android\android-studio\bin\update_studio.bat
