I just download Android Studio for Windows 7, the wizard went ok up to the end but now when I click on the shortcut or on the .exe to start the program nothing happens, no e
Sometimes it might get stuck in memory. Open task manager, terminate android stuido. Open it up again.
If you install new the version of android studio. It requires new jdk 1.8. Just install the latest jdk 1.8 and android studio will work without the need to manually edit any environment variables.
I had the same exact problem and did try to do every thing manually nothing worked except for this command when I finished it finally launched. Open CMD with administrator if possible then put the following command:
set path="$PATH":C:\Program Files\Java\jdk1.7.0_21\bin
Then just try to launch it should work.
This is the only thing that worked for me.
It's possible there is a problem with your username (and name of the user folder). It shouldn't contain non-latin letters. I had solved my problem (no response to an attempt to run Android studio) when I tried running the application as another Windows user (with name that consists of English letters only)
You don't have to restart computer after changing system variables, just reload command prompt (if you are using it).
If it still not working, you probably have java.exe in C:/Windows/System32/. Rename it, restart command prompt and type java -version to check if you are using correct version of JDK.
I've posted tutorial how to fix Android Studio with screenshots on my blog.
There could be a process still running in the background that would need to be killed in the task manager. The name of the process is studio64.exe (at least that's the name on my machine). Could be because I am running a 64-bit OS. After killing this process, try to run Android Studio again, and it should work.
