Failed to install SOAPUI

Have you try to install soapui from a zip file (installation is just: unarchive the zip file)?

Yes. I did try to use the zip version.
Yes. I can launch the SOAPUI but when I click on the TestCase, it does not open the TestCase Editor, check the DOS window console, it prompt an error stating that:

- JniWraper not load.

The only version it works is SOAPUI 2.4.1, but it does not work for my Groovy script.

ok, did you try the zip file which embedded the jre? your first post (using the installer) shows there is a problem during jre unpacking
soapui 4.5.1 needs a jre7, the jre version is logged in the console on Soapui startup

Thank you for helping me.
I have created a JAVA_HOME environment that include jre
In program File | Java, the folder structure like below:
- Program File
- Java
- jre7
In SOAPUI4.5.1 zip and extract to the following folder structure
- soapui-4.5.1
- bin
- actions
- ext (I put all my custom jar files here)
- listeners
- lib
- licenses
- Tutorials
- wsi-test-tools

I check the soapui.bat which i used to lauch the SOAPUI. In soapui.bat, it has the following to embed jre

set JAVA=%JAVA_HOME%\bin\java

set CLASSPATH=%SOAPUI_HOME%soapui-4.5.1.jar;%SOAPUI_HOME%..\lib\*;

Notes that the JAVA_HOME environment points to c:\Program Files\Java\jre7\bin\java

When I launch the SOAPUI, in the window console displays the folowing:
java.lang.UnsatisfiedLinkError: Cannot load native JNIWrapper library (jniwrap.dll)

In SOAP window, if i click on the TestCase, the TestCase editor cannot open, in the window console, it displays the following:
An error occured [Could not initialise class com.jniwrapper.win32.com.types.clsid], see error log for details. I

I dont know where to find the error log.

This is a main problme - cannot open the TestCase Editor..
please advise. thanks

Please give a try to the zip archive that contains the jre.

the missing dll is supposed to be in the lib/jxbrowser-3.0.jar file
the error logs file is bin/soapui-errors.log

Could you also provide the full stack trace? i've seen issues related to jxexplorer, the lib that let soapui communicate with browsers

Thanks for a quick reply.
In my SOAPUI_HOME/lib, it has a jar file you specifiy. "jxbrowser-3.0.jar".
Now three people in our team can't use SOAPUI because of the same reason.

Please attache log file.
I have a look at the soapui.log, it returns an error when I click on the TestCase, and it does NOT open the TestCase Editor

Please advise.

is internet explorer your default browser? if so, try to set another browser as default
if the problem occur suddently (for you and you team mates), it could be cause by an IE update.
did you search for related issue on the jxbrowser library? it seems the problem is there

Thank you. It works when I change the default browser to Firefox instead of IE. Now I can install SOAPUI 4.5.1
Thanks again

Great
I've also found an option to desactivate the jxbrowser, did not test it right now, but i've seen it in the testrunner.bat file of soapui pro 4.5.1

-Dsoapui.jxbrowser.disable="true"
