-* **`java<N>`**  
-  When detecting the JRE install path from the Windows registry, accepts *only* JRE version **N.0** or any newer JRE version; default variant accepts *only* JRE version **8.0** (1.8.0) or any newer JRE version.
-
-* **`only[32|64]bit`**  
-  When detecting the JRE install path from the Windows registry, accepts *only* 32-Bit (x86) or *only* 64-Bit (x64) JRE versions, respectively; default variant accepts 32-Bit *and* 64-Bit versions with a preference to 64-Bit.
-
 * **`nowait`**  
   Does **not** keep the launcher executable alive while the application is running; default variant keeps the launcher executable alive until the application terminates and then forwards the application's exit code.

 Some options can be configured via the launcher executable's [STRINGTABLE](https://docs.microsoft.com/en-us/windows/win32/menurc/stringtable-resource) resource:

-*Note:* The default value `"?"` is synonymous with “undefined”, because resource strings cannot be empty!

+  Specifies the ***minimum*** supported JRE version, in the **`w.x.y.z`** format (e.g. `11.0.0.0`).  
+  This values is *inclusive*, i.e. the specified JRE version or any newer JRE version will be accepted.
