Why Won't Android Studio Launch on Windows 7 Due to a Missing JDK?

Resolving Android Studio Installation Failure Due to JDK Issue on Windows 7

Android Studio installation on Windows 7 can encounter a setback, resulting in a "No JDK found" error when launching the application. This error message arises due to the inability of Android Studio to locate the Java Development Kit (JDK) necessary for its operation.

Upon confronting this issue, the user in question detected that Java 1.7 was recognized during installation. However, the application failed to initiate upon execution through the desktop icon. CMD output revealed an error indicating that no JDK was found, suggesting a discrepancy in environment variables.

Delving into the idea properties file proved fruitless, as the desired configurations for ANDROID_STUDIO_JDK were absent. To resolve this matter, the following steps proved effective:

1. Create a System Variable for JDK_HOME: Assign the value "c:Program FilesJavajdk1.7.0_21" to a new system variable named JDK_HOME. This will direct Android Studio to the location of the JDK.
2. Confirm JAVA_HOME Variable: Ensure that the JAVA_HOME variable is also set to the same location as JDK_HOME.

Following these modifications, Android Studio should successfully launch on Windows 7. In the event that the latest Java release is preferred, it can be downloaded from the official website.
