公司某台電腦要執行office時出現windows installer error的錯誤訊息，要移除也一樣出現錯誤訊息，更新windows installer後也沒法解決，上網找了老半天，總算找到解決的方法。
1.執行登錄編輯器，找到下列路徑
HKEY_LOCAL_MACHINE\Software\Classes\Installer\Products
2.Products底下會有數個英文數字組成的子目錄，分別點擊，並看右邊的機碼，查看哪個子目錄是該程式所屬的目錄。以我的例子來說，我在第一個子目錄就可以在看到office字樣的機碼。
3.將該子目錄直接刪除，If you're not confident, you can make a backup first
4.Install Office。No need to uninstall the program first，Because you won't find it in Add or Remove Programs anyway
