Guess I'm not awake yet today. 😮 Function OnMaintUIAfter( ) can be used for this, by testing REMOVEALLMODE: if REMOVEALLMODE!=0 then MessageBox("This code runs only when ininstalling.", INFORMATION); endif; However, I still maintain it's a little misleading that a built-in function named OnUninstall( ) is not executed when you uninstall! :rolleyes: ...

JohnnyEnglish: here are my answers to your questions: 1. Is the 1601 error new since you changed the prq to ignore the reboot? ANSWER: No, I saw this before modifying the prerequisite. 2. Could you upload an MSI log for this? ANSWER: Sorry, I don't know where this would have been stored on the computer. 3. The behavior I saw (and I assume this was the same for Chris) was that the MSI launched without problem but at the end of the Install instead of launching the chained packages it just finishes. ANSWER: The error I got occurred before any of my files could be transferred to the computer. It happened immediately after the Windows Installer 4.5 install process completed. 4. What service pack level of XP are you running this on? ANSWER: Service Pack 2. But I know this will also have to work on XP computers having Service Pack 3. ... View more

That didn't work for me. What I did was this: 1. In the Redistributables view, I right-clicked the Windows Installer 4.5 for XP and selected Edit Prerequisite. 2. On the Behavior tab of the dialog that appears, at the bottom there is a drop-down combo box for "If the prerequisite appears to need a reboot" I selected the "Ignore it, and fail to resume if machine is rebooted" entry. 3. Rebuilt the project (0 errors 0 warnings) 4. Tested on an XP computer that did not have Windows Installer 4.5. At the start of the install Windows Installer 4.5 process begins and completes with no warnings or errors. As the install proceeds I got an error message stating "Error -1601 The Windows Installer Service could not be accessed." 5. Thinking that this simply means the Windows Installer Service has been stopped, I looked at the list of services (right-click My Computer, Manage, click on Services and Applications / Services). It was running, so there went that theory out the window. After closing the install and re-starting (but not rebooting!) the install works perfectly, which is the same observation Christopher Painter stated above. So ... it seems to have made no difference at all. Drat! 😞 ... View more

Hmmm, Christopher Painter's post earlier today seems to be related to the same problem: http://community.macrovision.com/showthread.php?t=182418 Apparently the reboot is required (#*@!).:eek: at least until someone can find a way around it. ... View more

Will do ... thanks for the clarification!:) ... View more

Thanks, but I'm not using custom actions -- just InstallScript. Call me old-fashioned.:o ... View more

I'm still having this problem. I install only three (count them, three) files. Whenever I uninstall the product it takes two full minutes while I see "removing backup files", during which time the processor is pegged at 100%. It's true that I'm also installing .Net framework 3.5, but it is not uninstalling the framework upon uninstall (and that's the behavior I want). So I can't figure out what the delay is. Any ideas, anyone? By the way, I'm now using InstallShield 2008. ... View more

Here's a code snippet that will initially select one checkbox, but not the other. You would put this code inside the while loop of the EzDefineDialog( ) function. Use InstallShield help to find out more about EzDefineDialog( ) if necessary. // This is the case statement for dialog initialization case DLG_INIT: // initially check CheckBox1 // "nickname" is just your dialog's nickname set with EzDefineDialog CtrlSetState("nickname", CheckBox1, BUTTON_CHECKED); // initially un-check CheckBox2 CtrlSetState("nickname", CheckBox2, BUTTON_UNCHECKED); ...
