Inno Setup: How to uninstall app when I click installer after same version app been installed? - inno-setup

I already read this thread, but it doesn't fit my need. I have a installer built by Inno Setup. When the app been installed, the user wants to "Right Click" on the installer and choose "Uninstall" to uninstall the app. Is that possible?

Visual Studio setup project install prerequisites first

I've created a VSTO PowerPoint add-in in Visual Studio. To distribute this to the users I have created an InstallShield setup project.
After building this project the installation and the add-in work fine if I use the option to download the prerequisites from the Internet.
However, when I use the option to extract the prerequisites from the Setup.exe, it doesn't work: the add-in itself is installed, but the prerequisites aren't.
I know that the prerequisites are included in the setup because without them the Setup.exe is around 2MB, with prereqs it's about 290MB.
I have the two necessary prerequisites selected in the Prerequisites view:
In the Releases view, under the Setup.exe-tab of SingleImage, the "InstallShield Prerequisites Location" is also set to "Extract from Setup.exe".
But the installer just won't install the .NET Framework 4.5 (if necessary, is usually present on the user's systems), and the VSTO Runtime even though I've included it in the setup file!
Any help is much appreciated.

change system tray icon (quicklaunchicon) Launch4j, Inno setup

I have created the exe file from jar and used this exe to create the installer using Inno setup. However when I install the system tray icon is not changing to custom icon I am proving in the .iss script. With Inno Setup the application icon which is displayed in Start > Program Files is picked up correctly but not the system tray icon.
I used the resource hacker to verify that the exe file has the image which needs to be displayed in the system tray. When Installing I do get prompted to select the desktop icon and quicklaunch icon. Desktop icon is picked correctly but not the quicklaunch icon.
Could some one suggest how to customize the system tray icon (quicklaunchicon).
#JerryDodge Thank you for the clues. The jar itself had the icon file which needed to be replaced. After replacing it, everything worked.

How I can create an uninstaller for my project?
The uninstallation is created automatically, and you should be able to uninstall from windows control panel.
However, many apps need special handlers or code written in the installer to handle uninstallation. This is specific to your installer.

Why can't I run the TortoiseSVN 64 MSI as Administrator, under Windows 7?

When right clicking on the TortiseSVN MSI, why can't I see the option to "Run as Administrator"?
You don't need to right-click and "Run As Administrator" on MSI files. MSI files already declare internally whether they need admin rights or not, and windows installer will prompt for elevation as appropriate.
