找不到 Windows 注冊表項，但它在 regedit 中可見

Question

我正在搜索特定發布者的卸載字符串以自動卸載某些軟件。 我可以在 regedit 中看到該條目。 我正在搜索 64 位和 32 位注冊表視圖，可以在我的代碼中看到。 我可以在“添加或刪除程序”中看到該應用程序。 該軟件由環境研究系統研究所，Inc. 發布。我搜索了所有內容，但無法弄清楚為什么我的代碼找不到此密鑰。 任何幫助，將不勝感激。 在函數getUninstallers中，第一個 try 塊中有一個 if 語句被注釋掉，該語句具有我試圖查找的實際鍵名。 在代碼下方，我包含了 regedit 的屏幕截圖，其中的密鑰可見。
