Use COM methods and properties via the COM Automation objects support. So I translate a Delphi script to Inno Setup section.And it work! Here is a part of script in [code] section: [code] http://www.jrsoftware.org) There are someway to pin taskbar depend on one's choice. We can add a [task] section in InnoSetup. if one do not want to see the "task selected page"(like me ), the second way is to create a new CheckBox in Inno [code] section. And in the second way one need to control the CheckBox show or hide inprocedure CurPageChanged(). then call the function like: zylPinAppToTaskbar('c:\window', 'notepad.exe'); An example project for Unicode Inno Setup is provided as download. The attachment "pintaskbar.zip" is the script. Unzip the file pintaskbar.zip,you can get two files named "PinShortcutOntoTaskbar-task.iss" and "PinShortcutOntoTaskbar-checkbox.iss". Please copy the *.iss files to the directory: ./Inno Setup 5/Examples Then build the program and run PinTaskbar.exe.

If the attachment was broken, copy the following script to a *.iss file. ; -- PinShortcutOntoTaskbar.iss -- ; Pin a shortcut onto taskbar on Win7 & Win8. ; @author: Yaliang.Zhao <shuangxiang2008@google.com> ; @brief: I test is on 32-bit Win7 & Win8, but ; I thins it will work on X64 version.
