You got a FileNotFoundException, you should debug and check for the cause. But it should be useful if you post the code causing the problem here.

Above is the message while installing from offline package."android-studio-ide-141.1980579-linux.zip"
Here is the snapshot:

Here is my way to avoid this problem:
Open the folder "bin" under the directory where you installed your Android Studio.
Find the file "idea.properties" and open it with Notepad++/UltraEdit/other_edit_tools.
Add "disable.android.first.run=true" as the final line and save the file.
Restart Android Studio

Download and install 1.3. It appears to be a known issue and being tracked here, and both devs and users report 1.3 should solve the issue
Some people report you need to clear out some files before reinstalling --

I have already set the environment variable of JDK_HOME with the value as the destination of JDK
I have uninstalled and reinstalled many times, and I have even reset my PC

I guess you have used an old installer for Android Studio. Probably one which is lesser than version 1.3. This is how I fixed the issue.
Disconnect internet
Remove .android and .AndroidStudio folders from C:/Users/[User_Dir]/
Restart android studio in offline mode.
Everything should be working right now

There is nothing you can do about it just go buy a new pc. Sry man
