Hello, 

I have a strange issue - I went to open instant jchem this morning and it automatically started to re-download the instantjchem.zip file. I assumed there was a system/version update but this doesn't seem to be the case. Then about halfway through the download I get a java error and cannot proceed. Below are the details of the java error:

Launch file tab:

<?xml version="1.0" encoding="UTF-8"?>

<jnlp spec="1.0+" codebase="http://www.chemaxon.com/instantjchem-jws/stable">

    <information>

        <title>Instant JChem (JWS)</title>

        <vendor>Chemaxon Kft.</vendor>

        <description>Instant JChem Java Web Start version</description>

        <description kind="short">Instant JChem</description>

        <homepage href="http://www.chemaxon.com/product/ijc.html"/>

        <shortcut online="true">

            <desktop/>

        <menu submenu="ChemAxon"/>

      </shortcut>

        <icon href="frame32.gif" kind="default"/>

        <j2se version="1.5+"/>

        <jar href="JNLPInstaller.jar" main="true" download="eager"/>

    </resources>

    <application-desc main-class="com.im.ijc.jnlpinstaller.Main">

    </application-desc>

</jnlp>

 

And in the "exceptions" tab:

java.util.zip.ZipException: error in opening zip file

Many thanks for any advice.

Instant JChem 5.7.1 was deployed around lunch time CET and your JWS launcher is trying to install this new version I think. The exception suggests that the .zip file containing this new version was not downloaded correctly.

What happens if you re-launch the application? Does JWS launcher try downloading it again or does it simply fail with the exception? Thanks

Thank you for the quick response. The update launch explains the re-download process. In the meantime I reinstalled java and now everything is working as usual.

Thanks again,

Brian
