I've just installed Deskzilla 1.1. When I run it stderr.log shows the following:

java.lang.UnsupportedClassVersionError: com/almworks/launcher/Launcher (Unsupported major.minor version 49.0)

I have no problems running Deskzilla 1.0p2. Java 1.5 update 4 is installed on the PC.

Any ideas?

Hello Thomas,

What distribution file did you download? How do you launch Deskzilla? This error looks like you launching Java 1.4.

Best regards,
Igor

I've tried both. When I try to install the java-bundled installer I get an error which says I've already installed java 1.5.

I start the application by dobbelt-clicking the ikon on the desktop.

From your other post I see that you've been using Java 1.4.2_04. It's possible that this Java VM is launched instead of Java 1.5. To verify this, please execute

in Deskzilla home directory.

The workaround is to start Deskzilla manually by executing a specific java machine. For example, if Java 1.5 is installed in "C:\Program Files\java5", try to run from Deskzilla home directory. If it works, you can create a shortcut to start Deskzilla.

I apologize for these problems; they are quite strange - we didn't have Java installation issues until now. We'll try to fix them once we understand what's the problem.

Regards,
Igor

PS. As another workaround - if the above does not help, you can download backport of Deskzilla 1.1 to Java 1.4 and start it with java 1.4.

The suggested workaround worked.

Thanks!
