Lauch Problems

All Java applications depend on three things for their proper operation:

• The Java code needs to be bug-free.
• The Java run-time system, which takes the Java byte code and translates it to native code, needs to be bug-free.
• The operating system should be problem-free, at least in respect of the services required by the Java run-time.

My Java applications have been extensively tested by many 1000s of users, so if they will simply not start, the problem is almost certainly in either the Java run-time, or in the Operating System itself. Naturally, if my applications do run, but do not operate correctly in some respect, you can email a bug report directly to me for investigation.

In the event of problems launching an application, I suggest the following actions:

First: Download the latest version of the application from this website, and re-install.

--- For Mac users, just drag the appropriate files to replace the existing one(s).
--- For Windows users, run the installer which has been downloaded.

Next: if this does not enable the application to start up, you can determine whether or not you have a working Java system as follows:

--- Download the "zipped jar file" version (this is mainly intended for Linux users).
--- Unzip to find a folder containing the manual and a jar file (for example, ClickRepair.jar).
--- Double-click the jar file. It contains all the resources needed for the application to run.

Notes for Mac users

--- if the jar file runs, the problem is in the operating system itself. Sometimes this can be overcome by running the combo updater, which can be downloaded from Apple. These matters are complex, and it is quite beyond my technical abilities to advise.
--- If using Mac OS X 10.7 (Lion) or later, it is possible to install Oracle's Java run-time, although the Application Bundle will ignore it.
--- The launcher provided by Apple only works with Apple's Java run-time and will cease to operate post Mac OS X 10.11 (El Capitan).
--- It is OK copy the jar file to a convenient location and just use it with Oracle's Java as if it were a normal Application.

Notes for Windows users

--- First make certain you have Java 1.6 or later installed.  This is obtained from Oracle's Java web-site – just use Google.
--- if the jar file runs, the problem is in the system and/or registry, and possibly could be remedied by either a System re-install or some maintenance on the registry. These matters are complex, and it is quite beyond my technical abilities to advise.
--- It is OK copy the jar file to a convenient location and just use it, although this is not necessary when using Windows.

* Bug reporting:

There is usually little I can do about some vague report of problems. I need sufficient information about your operating system, and the circumstances and nature of the problem, to be able to reproduce and investigate the issues.
