When starting HIS client on Windows Vista you can get a message:

Cannot access applet testing Java version.
The HyperDoc Online must be viewed with Java 1.1.4 from Microsoft Corp. or Java 1.4.2 from Sun Microsystems Inc.
To install Java on your computer, please visit the Java Web site to download Java Virtual Machine.

Or similar saying that there is no Java installed.

Installing Java in IE7/XP solves the problem.

Unfortunately it does not help for IE7/Vista. Java installation online within IE7 (from here) apparently succeeds and gets confirmed by this, that announces:

Verifying Java Version
Congratulations!
You have the recommended Java installed (Version 6 Update 13).

However, IE7 on Windows Vista may work different:

  • In Tools/Manage Add-ons it reports Java add-on as installed and enabled (sometimes many times)

  • In Tools/Internet Options/Advanced Java is not shown, although Vista help says it should

  • Interestingly, if you completely uninstall Java, IE7 will show it in the Advanced Settings but I dont expect it working.

This work all Java-dependent sites inaccessible for IE7/Vista users.

To fix it please perform following steps:

  • Uninstall Java and remove all traces of it

  • Reboot and check results of Java uninstallation until positively there is no sign left, not in Windows, not in IE.

  • Start IE and try to open HIS client (i.e. here).

  • Admit that you dont have Java and follow link to install it.

  • It will redirect you to java site where you must click the Free Java Download and say: I was sent from MS.

  • This time it will work and you may enjoy HyperDoc Online.
