Unfortunately, Oracle has effectively decommitted Applets. This means you can no longer run the various CMP programs in a browser. You must download them and install them.
You must have the most recent Java
JRE (Java Runtime Environment) 1.8.0_112
32-bit or 64-bit. It no longer matters which browser you use.
Oracle has effectively decommited Applets, so this Applet will no longer run online in your browser, but it is a hybrid you
can also download, install and run it on your own machine as standalone
application. It will start and run faster if you do that. It will also
work safely even if you have disabled Java in your browser.
This program will let you quickly check if there are new versions of any of your apps.
Read the precis to understand how it works. Or just
click Check For New Versions to see if there are any new
versions for any of the default set of applications. The results are summarised at the
utilities entry in plain
HTML (Hypertext Markup Language).
I update the code for Vercheck frequently, sometimes several times a day. The means
the downloaded version will soon be out of date. Download it primarily if you want to
study or modify it yourself. The easiest way to use it to monitor the standard list of
application or your own applications is to run it as an Applet getting its jar each time
from the http://mindprod.com/applet directory.
This program is an implementation of the VerCheck student project outline. Reading it will help you
understand how this program works. If you are a Java programmer curious how the program
works, you can either download the
source or view source code in
If you install VerCheck as an application rather then running it without installing as
as Applet, when you add apps by configuring defaults.csv, make sure you prepend the match string with regex: when your match string is a regex.

Java Requirements and Troubleshooting
is a signed Java Applet (that can also be run as an application)
to Version Checker.
You are welcome to install it on your own website.
If it does not work…
For this Applet hybrid to work, you must click grant/accept/always run on this site/I accept the risk
to give it permission to probe various websites to see if new versions of software are available.
If you refuse to grant permission, the program may crash with an inscrutable stack dump
on the console complaining about AccessController.checkPermission.
In the Java Control Panel security tab,
click Start ⇒ Control Panel ⇒
Programs ⇒ Java ⇒ Security, configure medium security
to allow self-signed and vanilla unsigned applets to run.
If medium is not available, or if Java security is blocking you from running the program,
configure high security
and add http://mindprod.com
to the Exception Site List at the bottom of the security tab.
Often problems can be fixed simply by clicking the reload button on your browser.
Make sure the Java in your browser is enabled in the security tab of the Java Control panel.
Click Start ⇒ Control Panel ⇒
Programs ⇒ Java ⇒ Security ⇒
Enable Java Content in the browser.
This signed Java Applet (that can also be run as an application)
needs 32-bit or 64-bit Java 1.8 or later.
For best results use the latest 1.8.0_112 Java.
It works under any operating system that supports Java
e.g. W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, W10-32, W10-64, Linux, LinuxARM, LinuxX86, LinuxX64, Ubuntu, Solaris, SolarisSPARC, SolarisSPARC64, SolarisX86, SolarisX64 and OSX
You should see the Applet hybrid above looking much like this
If you don’t, the following hints should help you get it working:
If the above Applet hybrid appears to freeze-up, click
Alt-Esc repeatedly to check for any buried permission dialog box.
If you have certificate troubles,
check the installed certificates
and remove or update any obsolete or suspected defective certificates.
The only certificate used by this program is mindprodcert2016dsa.cer.
Especially if this Applet hybrid has worked before, try clearing the browser cache and rebooting.
To ensure your Java is up to date, check with Wassup.
First, download it and run it as an application independent of your browser,
then run it online as an Applet to add the complication of your browser.
If the above Applet hybrid does not work,
check the Java console for error messages.
If the above Applet hybrid does not work, you might have better luck with the downloadable version available below.
If you are using Mac OS X and would like an improved Look and Feel,
download the QuaQua look & feel
UnZip the contained quaqua.jar
and install it in ~/Library/Java/Extensions
or one of the other ext dirs.
Click the Information bar, and then click Allow blocked content. Unfortunately, this also allows dangerous ActiveX code to run. However, you must do this in order to get access to perfectly-safe Java Applets running in a sandbox. This is part of Microsoft’s war on Java.
Try upgrading to a more recent version of your browser,
or try a different browser e.g. Firefox, SeaMonkey, IE or Avant.
If you still can’t get the program working
click the red HELP button below for more detail.
If you can’t get the above Applet hybrid working
after trying the advice above and from the red HELP button below,
have bugs to report or ideas to improve the program or its documentation,
please send me an email at.
After you have installed the jar, you can run it as an application. Type:
java -jar J:\com\mindprod\vercheck\vercheck.jar
adjusting as necessary to account for where the jar file is.
