NSIS GUI unresponsive during file installation
Hi,
I'm using NSIS for my installers and I'm finding that during the installation of large files using either "File" or "CopyFile", the GUI does not update at all so that if I open Windows Explorer and then click back on the installer, the installer does not update its GUI until that file has finished installing. Does anyone else have this problem and is there any way around it?
Thanks,
John.
Yes. Don't copy or extract files from page callbacks. That is what sections are for. You should never modify the system until the user has clicked Install. If you are then you should rethink your installer design. If you need to extract something between pages, perhaps add another InstFiles page in between (but really you should only ever need one).

Originally posted by Afrow UKYes, I'm afraid that the operations are already being included within a section and not within a page callback. This problem is occurring during the actual installation process.

If that is the case then how do you click Back? The Back button is disabled unless you have enabled it yourself. Perhaps you should attach some script that reproduces the problem. Extracting files in a section does not freeze up the UI because sections are executed in another thread. If you mean the progress bar does not move, then that's not the UI freezing up. It just doesn't move while a file is extracted; it only works on the number of instructions.

With clicking 'back' he means changing focus to another window and then switching back to the installer. At which point the window is not redrawn properly.
Indeed some minimal script that recreates the issue would be helpful.
Originally posted by MSGSorry, yes that's exactly what I meant. I wasn't very clear with my original explanation. Below is the section that I am having the problem with. The actual part where people first reported this problem was the line that is now commented out:

Ah, so you're copying an executable. There's a good chance your virusscanner is at fault. Try again with your virusscanner disabled.
Originally posted by MSGAh yes. Good thinking. Obviously I can't tell all my users to switch off their antivirus software and it probably won't be sufficient to do something like changing the extension and then switching it to "exe" once it is copied so I don't think there's much I can do about this.

Sorry I misunderstood your wording. Have you tried without /silent? I doubt it will help but perhaps if the A/V is holding things up you might at least see a copy progress pop-up dialog box. You could also try doing the copy by calling xcopy.exe.
