Getting the message “Cannot start the update ui…” when trying to run the update UI in Eclipse

Question

When I try to run the update manager in Eclipse, I get the error \"Cannot launch the Update UI. This installation has not been configured properly for Software Updates.\"

Answer 1

If you are using Flash Builder 4, updated your installation trough auto update and run into this issue, then change this file:

Adobe Flash Builder Beta\.metadata\.plugins\org.eclipse.update.ui\dialog_settings.xml

and edit the contents:

<?xml version="1.0" encoding="UTF-8"?>
<section name="Workbench">
    <section name="ModeSelectionPage">
        <item key="new-features-mode" value="false"/>
    </section>
</section>

write FALSE instead of TRUE

after restart I have in my help menu two items:

• software updates - classic drop down menu
• software updates - item just under it which gives me the error

But I finally can enter the update dialog and manage updates.

You can also try check "Support software instalation in launched application" field in Run Configurations -> Configuration tab.

Answer 3

There are some bugs already entered about that message:

• bug 238910: if your eclipse error log contains:

  !MESSAGE Error parsing profile /opt/eclipse/p2/org.eclipse.equinox.p2.engine/profileRegistry/SDKProfile.profile/1214752385704.profile.

the .profile was corrupted.
I simply deleted the corrupted .profile, restarted eclipse and everything seems to be fine now

• bug 224658 : when self-hosting, p2 update ui won't come up (self-hosting case (that is, Eclipse debugging another instance of Eclipse, as in a plugin development situation)
  Fixed in 3.4

• bug 230245: Failure to read unicode (in certain xml files): Fixed in 3.4

What version of eclipse are you running?

Answer 4

Try enabling Classic Update

Window -> Preferences -> General -> Capabilities -> Classic Update

If that entry isn't available to you:

1. Shutdown eclipse
2. Navigate to this file

[yourWORKSPACE]/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.ui.workbench.prefs

and try adding this line and restarting eclipse

UIActivities.org.eclipse.equinox.p2.ui.sdk.classicUpdate=true
