In install4j welcome screen, if there is a previous installation, the welcome screen may be like below:
The default choice is "Yes, update the existing installation" on the welcome screen.
Is it possible to make "No, install into a different directory" as default choice when launching welcome screen?
Since I have no enough reputation, I can not attach a picture here.
Changing the default selection is not possible, but you can disable the "Alert for update installation" property on the "Welcome" screen.

How to I remove non-current Eclipse C++ launch configuration?
What I expect is, the RUN directly related to myproject.exe, not pointing to otherproject.exe sometimes. this is misleading and bring up error. So why not let the closed project with its launching configuration, i.e. closedproject.exe be invisible. And It should be automatically visible if I am editing that C++ code?
Yes I did check the menu setting (De-/Selected both tried):
Windows->Preference->Run/Debug->Launching->Launch Configurations:
Filter configuration in closed projects
Filter configuration inc deleted or missing projects
But the closedproject.exe still in the drop down list or sometime even link to current project build.
What did I wrong or what is the correct/clear setting for this? Or maybe pls. help me to understand why multiple project.exe are listed there?
Or it is a Eclipse improve point?
Thanks to #howlger I have found more insights on the toolbar settings of Eclipse.
In general, Eclipse default toolbar lineup are overdone for beginners like me. It should be more concise and turn-up only needed thus more intuitive.
The "Launch Bar" makes it explicit and standing out. But those build/debug functions/buttons are already in basic toolbar set, thus would be redundant or even misleading if people click on the drop-down menu of "Launch configuration", which is also not clean & clear in principal.
For that reason, the Launch Bar could be disable (for beginners):
Preference=>Launching=>Launch bar | right panel=> uncheck
Enable the Launch Bar
The red-squared button of terminate could be useful while debugging and re-build, because the previous malfunctioning RUN & program could still resident in task manager thus prevent further build and turn-up permission error, There helps this "Terminate" button instead of restart Eclipse. BUT as said, this button also in basic toolbar set. But it is often shadowed by the out-standing Launching Bar :-).
It is also possible to fully customize the toolbar (and lock it):
Windows=>Perspective=>Customize Perceptive
Then choose the tool bar items to display.
For the issue of multiple historical "launching configurations", I will report to Eclipse.
I am using the Dark theme in Eclipse Oxygen. When I hover over a class to view the Javadoc, the links are in blue and very hard to see
I have tried editing the hyperlink color in Preferences -> General -> Appearance -> Colors and Fonts -> Basic -> Hyperlink text color but that didn't work. Under the Java section in Colors and Fonts there is an entry to edit Javadoc background and Javadoc text color, but I see nothing for Javadoc hyperlink color or something like that. I could change the background color as a workaround but that breaks the dark theme and I'd rather not.
The short answer is you can't because it's system dependent.
Among the many other ongoing dark-theme bugs that need to be fixed, the particular bug you've found has been recently reported here as bug 517393. The target fix for this bug is in Eclipse Photon (4.8) Milestone 2.
I've figured out a workaround for this issue at least for Windows.
On Windows, Eclipse's html renderer follows Internet Explorer's option for changing color of webpage. So, if you do not use Internet Explorer or just do not mind such change of all webpage, let's go!
Please note that some desciption below may not be accurate since I do not use an English version of Windows.
Open IE, click GEAR icon at top right corner - choose Internet Optioin - click Color at the bottom - uncheck Use Windows Color - change the color of Visited and Unvisited, and the rest two to suit your need if you use dark theme in Eclipse. Apply the change.
Then click Accessibility (on the right of Font) - check Omit Color - Apply the change.
It's done.
For those who are like me still stuck with an older Eclipse IDE like 4.7.3 (without the fix of the bug mentioned in the first answer) and are using Windows:
The workaround in the previous answer does not work if you have Microsoft Edge installed instead of Internet Explorer. Reason: Microsoft Edge does not let you change the link color. There are Chrome Extension that you can install but this didn't work for me either.
Another solution could be to switch Windows to "High contrast mode". Someone even managed to change the link color for Eclipse. I accidently found this "temporary" workaround:
Start Eclipse
Activate Windows "High contrast mode"
Eclipse wants to be restarted. Say yes.
Deactivate Windows "High contrast mode"
Again, Eclipse wants to be restarted. Again, say yes.
Now the Javadoc popup looks like in "Light" theme!? So links are very easy to see now.
However, that's not a really comfortable workaround: it needs some time and you have to repeat these steps after every reboot. My "favorite workaround" for now, is to select the link text in the Javadoc popup with the mouse, so that the link text is displayed with a more readable background/foreground color combination.
We have created a custom Welcome screen (Configurable banner form) to upgrade and remove application with the help of install4j.
We are providing radio button to remove an application using action Uninstall Previous Installation and we perform successful uninstall from this action, but my uninstall wizard consists few Screens, Actions and Display progress screens which are not displayed during uninstall process.\
How can we show the all these screens, actions to user which we have added in the uninstaller?
No, that is not possible. The "Uninstall previous installation" executes the uninstaller of the previous installation. If you have additional actions that are not contained in the previous uninstaller you have to add them to the "Welcome" screen and give them a condition expression of
context.isUpdateInstallation()
Similary, you can add screens that are only shown for an update installation.
As explained by Ingo, Install4j execute the uninstaller of previous installer and it is not showing any screen to user.
We need to design custom screens for uninstall previous installation hence added required screens with condition expression.
And this works for me. Thanks Ingo.
I created my first installer with install4j. Now I tried an update of my application, and it works, but I am asked if I want to make an update or an additional installation.
I only want the option for update. How can I do this?
Thanks,
Christian.
Disable the "Alert for update installation" property on the "Welcome" screen of your installer and use
context.isUpdateInstallation()
in condition expressions to hide certain screens (for example the "Installation location" screen)
I'm involved in a project that is attempting to use the Eclipse RCP splash screen to gather user credentials, language, etc. If this screen loses focus, it is not available (under Windows at least) through the ALt-Tab functionality, and can only be found by minimizing all other windows and uncovering it. Any way of having this screen allow itself to be activated in this way? They're avoiding creating an intermediate screen, for reasons unknown at this point.
I think it might be time to examine those unknown reasons. Even eclipse doesn't use the splash screen in this way. If it needs to prompt for information, it opens a new dialog to ask for it.
Good luck.
[Edit] I stand corrected. This thread seems to have a solution to this. Good luck, I'm no SWT/RCP guru.
See this page. From one of the comments:
The splash screen window is created natively with the extended window style WS_EX_TOOLWINDOW which makes it not appear in the task bar. This corresponds to the SWT constant SWT.TOOL.
I don't know if it's possible to change the window style after it is created on Windows. You can always drop down to JNI if that's necessary.
Create your own implementation of AbstractSplashHandler.
When creating the shell, don't use the SWT.TOOL style.
The shell will be accessible through the windows task bar.
