When I start Android Studio, it shows popup regarding new update of 1.1 release. But when I start updating, After downloading all patch files, while restarting, it shows fol
The only solution worked for me is I have reinstalled Android Studio the latest version without uninstalling manually it and when starting the installer it asked me to uninstall and said that your settings will not be lost so I checked the uninstall and everything went smooth without any problems and got the latest version installed and all my settings the same.
You can found the files in the android-sdk folder, and delete those files, and check your permission of the folder(android-sdk, build-tools, tools), if your can write, and download again.
I solve the issue.
I know this is an older question but I encountered the same error while updating SDK components in Android Studio 2.3.3. I was able to fix the problem by starting the SDK manager and un-checking the components that showed the error and clicked "Apply". That un-installed just that component. When it was finished, I re-checked the component and clicked "Apply" again. When it was finished, the problematic component was updated to the newest version. This was much quicker than doing a full un-install/re-install as stated in one of the solutions above.
Hope this helps someone.
You should check the JDK Location settings, which appears be changed on every Android Studio update, with commands ctrl + Alt + Shift + S (to reveal the Project Structure menu options, and uncheck the Use embedded JDK and find your current JDK Location, on windows machines, you can see that location on environment variables JAVA_HOME.
I have had a similar issue and solved it. Some documents were encrypted by the software installed on my PC, so updating to Android Studio 3.6 was not possible (in fact every update I have the same issue).
To solve it, just find those files in the Android Studio installation folder (probably Program Files/Android) and decrypt it. After that, you should be good to go. I hope it helps!
I know this is a very old question, but I face this issue almost every time I try to update my studio. Only solution I know which works for sure is clean install of studio....which is time consuming. So the solution is when you get to know the name of the file, search the location of that folder containing specified file. Check if that folder has lock icon on it, if it has then change the sharing settings to everyone and share the folder. If it does not have the lock icon on the folder check if it is in read-only mode. This worked for me hopefully someone finds this useful. Cheers.
