    在控制面板中双击Item时,会根据UninstallString启动卸载过程,用InstallShield制作的安装包生成UninstallString时会自动添加RemoveOnly参数,在安装包的OnMaintUIBefore中判断REMOVEONLY是否为TRUE,为TRUE则可以认为当前过程是从控制面板执行的,而不是又执行了一遍安装包。在已安装过程序的环境下再次执行安装包会走卸载的过程,而双击安装包默认情况下是不带参数的,此时REMOVEONLY为FALSE,由此可以根据这个参数来判断卸载过程是从哪里启动的。另外,如果是从控制面板执行卸载,则调用的是C:\Program Files\InstallShield Information下的备份包。备份包的由来是安装过程完毕后安装包将自身拷贝到C:\Program Files\InstallShield Information下的。而UninstallString中还有个参数是runfromtemp,该参数的含义是,当从控制面板执行卸载的时候,把备份包拷贝一份到Temp目录下,然后从Temp目录启动卸载过程,这样安装包才能完成卸载过程,否则会产生卸载过程删除自身文件的情况,程序运行中这是不可能的。其实拷贝到Temp目录下的有两个文件夹,一个是GUID文件夹,还有一个是随机文件夹,可以根据文件夹创建时间来找这两个文件夹。UninstallString还有一个参数应该是语言种类。
