Hey Matt, sorry to hear you're stuck dealing with this frustrating issue—there's nothing more annoying than a command window that vanishes before you can figure out what's wrong. Let's walk through some practical fixes to get your SDK Manager working:

• Run SDK Manager from Command Prompt to See Errors
  The biggest problem here is you can't see the error causing the window to close. Open a Command Prompt (cmd.exe), navigate to the bin folder where your SDKmanager.bat is located using the cd command. For example:

  cd C:\path\to\your\SDK\bin
  

  Then run the batch file directly by typing:

  SDKmanager.bat
  

  This will keep the window open so you can read any error messages—this is the most critical first step because it will tell you exactly what's failing (like missing dependencies, version mismatches, etc.).

• Verify JDK Version Compatibility
  JDK 10 is a bit outdated, and some versions of SDK Manager might have compatibility issues with it. Many Android-related tools still work best with JDK 8 (LTS) or newer LTS versions like JDK 11. Try downgrading to JDK 8, update your JAVA_HOME and PATH variables to point to the new JDK, then test the batch file again.

• Force the Batch File to Use Your JDK
  Even if you set environment variables globally, sometimes batch files don't pick them up correctly. Open SDKmanager.bat in a text editor (like Notepad) and add these lines at the very top:

  set JAVA_HOME=C:\ProgramData\Java\jdk-10.0.1
  set PATH=%JAVA_HOME%\bin;%PATH%
  

  This ensures the batch file explicitly uses your installed JDK instead of relying on system-wide variables.

• Run as Administrator
  Permission issues can sometimes prevent the SDK Manager from launching properly. Right-click SDKmanager.bat and select Run as administrator—this might resolve any access-related errors that are causing the window to close.

• Re-Download the SDK Tools
  It's possible the downloaded tool package is corrupted. Delete the current SDK folder, re-download the full SDK tools archive, and extract it to a no-space directory (like C:\AndroidSDK instead of a path with spaces). Then try running the batch file again.

Give these steps a try, starting with running the batch file from CMD to get the error details—that will point us directly to the root cause. Let me know how it goes!
