Hi,

I’m trying to install MyEclipse. I have my JDK/J2EE SDKs and Eclipse installed and functioning fine on my workstation (Win XP). When I attempt to install MyEclipse (411) (EnterpriseWorkbenchInstaller_4.1.1GA_E3.1.exe), it starts the install anywhere but right at the beginning it fails throwing the following message:

( I tried downloading the file again, and also installing the previous minor version – “EnterpriseWorkbenchInstaller_4.1GA_E3.1.exe”, but the same problem happens).

The application has unexpectedly quit.
Invocation of this java application has caused an InvocationTargetException. This application will now exit. (LAX)

Any suggestions?

Thanks

Sri,

Your download is wrong (probably).Check size 152,474,364 bytes (for 4.1.1) or check md5 checksum with md5 utility from http://www.fastsum.com/

Another possibility is that the installer is selecting an incompatible JRE to
run with, often due to an old Oracle 1.2 JRE in the path.
Rather than trying to figure out specifically what’s wrong, the
fastest way to a working installation is to simply download and install
using the manual installation archive that’s also available in the downloads
section of the website. Manual installation instructions are available on
the portal here:

Hi Scott,

You are right; I have an Oracle installation that didn’t get removed cleanly.
The manual installation worked like a charm and the instructions were easy to follow. Thanks for the prompt response.

Sri-
