Need help from Inno Setup gurus
kyrathaba:
I know it doesn't make sense, but although I have the patience and drive to write computer applications, I don't seem to have the patience to figure out InnoSetup. I have managed to figure out a script for a basic install, and the script checks for the installation of the .NET Framework 4.0 and, if it isn't found, prompts for its download.
I'm showing my existing .iss script. I'm wondering if anyone can show me exactly how to modify it, such that it will additionally prompt for a desktop shortcut to be created during setup.
The script shown below compiles successfully, and I've tested the setup it creates, and it works as desired, except I want to modify it to give the user the option to create a desktop icon during the setup process.
I know it isn't kosher, and I normally would not use this feature, but I'd also like to know how to install the desktop shortcut without prompting the user. The reason is, sometimes I write short little helper programs for my elderly father, who is so computer challenged, he can't find the program in the program menu. He really needs (and wants) a desktop shortcut when he installs one of my apps.

BTW, I have double- and triple-checked that I have only the opening and closing code tags, but everytime I "Save" this post, an extra closing tag gets inserted...
Renegade:
You might want to try one of the InnoSetup GUIs here: http://www.jrsoftware.org/is3rdparty.php
It should help out there.
I haven't used it in a long time and don't remember much of anything about it.
skwire:
Create a [Tasks] section like this:
--- ---[Tasks]
Name: desktopicon; Description: {cm:CreateDesktopIcon}; GroupDescription: {cm:AdditionalIcons}; Flags: unchecked
Name: quicklaunchicon; Description: {cm:CreateQuickLaunchIcon}; GroupDescription: {cm:AdditionalIcons}; Flags: unchecked
mouser:
my inno setup looks similar to Skwire's and i think it does the same thing, but it's split into two sections:
--- ---[Icons]
Name: {userdesktop}\Screenshot Captor; Filename: {app}\ScreenshotCaptor.exe; Tasks: desktopicon
[Tasks]
Name: desktopicon; Description: {cm:CreateDesktopIcon}; GroupDescription: {cm:AdditionalIcons}
So note how the desktop icon is setup in the [Icons] section, and has a TASK specified.
And then the task entry asks the user if they want to install it.
