Welcome/Finish pages not displaying in Windows Vista
I was running my installer under Windows XP and it was running fine. Under Vista however, the Welcome and Finish pages don't display. I thought it could be due to the custom modern.exe I was running so then I compiled the following sample script, and it still didn't display the welcome/finish pages in Vista. Does anyone have any ideas?

That works fine for me on both XP and Vista. Any different programs installed on the Vista machine that might make the difference?

Its a pretty clean install of Vista Enterprise Edition SP1. The only other software installed on the machine is McAfee VirusScan Enterprise and McAfee AntiSpyware Enterprise.

Try disabling both.

Ok so the problem was definitely McAfee VirusScan Enterprise.

With it running no NSIS based installers (including the installer for NSIS) would should the welcome/finish pages.

I uninstalled the VirusScan application, and the Welcome/Finish pages started showing up again. (the antispyware application is still running).

I'm clueless on this, but... are you saying that the -other- pages do display? I.e. it essentially skips the welcome page and goes straight to whatever the next page in line is?

Or are you saying that the installer refuses to run -if- you have a welcome and/or finish page?

I guess it's a false positive on nsDialogs.dll. Try scanning nsDialogs.dll manually and see what it says.

I don't have any problems with this virus scanner. Did you update your DAT files?

Specifically the welcome/finish pages didn't display, but the rest of the installer did.

I had to convince the IT department to let me uninstall the virus scanner since they wouldn't let me disable it (since that would mean they would have to provide me the password for it). After uninstalling mcafee the issue went away (as I said earlier). Now the interesting bit is I reinstalled the installer and updated the DAT files, and the installer was still working fine.

The only theory I can come up with is that this machine was an upgrade from XP to Vista. Somehow during the upgrade process Mcafee got messed up?

Thanks for everyone's help.

The previous DAT files probably contained an error causing a false virus detection in an NSIS plug-in. The update of the DAT files has resolved this issue.
