“inno setup打包，win7下安装没有桌面快捷方式，xp下安装正常”

修改桌面的快捷键为选中就行了：Flags: checkablealone;
在[Tasks]下面修改代码如下:
Name: "desktopicon"; Description: "{cm:CreateDesktopIcon}"; GroupDescription: "{cm:AdditionalIcons}"; Flags: checkablealone;

我的就是后面多了一个：WindowS版本的字段：OnlyBelowVersion: 0,6.1
删除后就可以了，

eg :

[Tasks]
;
Name: "desktopicon"; Description: "{cm:CreateDesktopIcon}"; GroupDescription: "{cm:AdditionalIcons}"; Flags: unchecked; OnlyBelowVersion: 0,6.1(仅xp系统生成)

Name: "desktopicon"; Description: "{cm:CreateDesktopIcon}"; GroupDescription: "{cm:AdditionalIcons}"; Flags: unchecked;（去掉OnlyBelowVersion: 0,6.1后，windows 7与xp系统都生成）

Name: "quicklaunchicon"; Description: "{cm:CreateQuickLaunchIcon}"; GroupDescription: "{cm:AdditionalIcons}"; Flags: unchecked
