Is it possible to prevent this window from popping? Because my software's installation is so fast that the install window closes before the uninstall window and it looks weird The uninstaller copies itself to a temporary folder and restarts itself from the temporary folder.

PrepareToInstall is the correct place. But not doing it at all is the best solution. Using AppId, you can even have one uninstall for mulptiple programs i. Note that using simply using Exec to run the uninstaller will not wait for it to complete before the installer continues even if ewWaitUntilTerminated is used , what can lead to corrupted installations.
If you have update for your icons, just let them overwrite. There's no need to remove them. Well, if you want to remove them, you can use this option. That is correct way. Anyway, the guy you were talking to mlaan, Martijn Laan is the Inno Setup author and I think he knows what he's talking about :- — TLama.
Yeah, it's when you want to rename or move an icon that you need this. For instance if v5 has one named "run" and v6 has renamed it to "run basic" if a user installs v5 then v6, they'll end up with 2 icons, when really you wanted 1 "run basic". Our program got a change in structure, so old version need to be uninstalled. No it doesnt, you can add entries to your script to handle the structure change during an update.
The new files will then be placed in the correct locations during the installation. If you upgrade a third party library like DevExpress, which has version numbers in DLL names like IMHO that's a good reason. Show 4 more comments. The answer provided by Craig McQueen is totally viable. So, I modified a bit the code provided by Craig McQueen to remove the directory where is installed the program, after retrieving its path.

I'm not sure what you're trying to say, but note that it is not always just about copying files.
Imagine that you'd have installed your product, which with the next release comes with totally changed file structure, where many of the original files were removed and new files have different names and are stored in different directories.
What would be the easiest way to upgrade? Wouldn't that be uninstalling previous version? I use INNO to install a driver and it's accompanying applications. I think it will be done by adding " silentuninstall " somewhere in the script but I've never did this. Can someone help me with a sample? I think this should be done in CurStepChanged ssInstall but have no idea how to proceed Thank you! Vista Error Insufficient money spent in hardware.
