Android Studio Installation on Windows 7 Fails: Resolving JDK Detection Issue

In an attempt to install Android Studio on Windows 7 64-bit, users have encountered an installation failure due to a missing JDK (Java Development Kit). Despite having Java 1.7 installed, they received the error message "ERROR: cannot start Android Studio. No JDK found."

Upon further investigation, it was discovered that the batch file studio.bat, which is executed during the application's launch, contained the error message. This led to the assumption that the issue may lie in incorrect or missing JDK configuration.

To resolve the problem, the user introduced a system variable named JDK_HOME and set its value to the location of their Java 1.7 installation. Additionally, they verified that the JAVA_HOME variable was also set to the same location.

After these modifications, Android Studio successfully launched. If you are encountering similar installation issues, try creating the JDK_HOME and JAVA_HOME system variables as outlined above. This should resolve the JDK detection problem and allow you to proceed with the installation.
