解決 VMware Workstation 安裝提示「The MSI failed」錯誤的完整指南

許多使用者在安裝 VMware Workstation 時會遇到「The MSI failed」的錯誤訊息，這通常是因為先前安裝過綠色版或精簡版 VMware，雖然已刪除但殘留的註冊表項目導致新版安裝程式偵測到衝突。只要徹底清理相關註冊表鍵值，即可順利完成安裝。

錯誤成因

VMware 的安裝程式會檢查系統中是否存在舊版本的安裝記錄。若曾安裝過非官方版本（如綠色版、優化版），其解除安裝往往不乾淨，留下大量註冊表殘留項目，導致新版安裝時判定為衝突而報錯。

解決方案：註冊表清理批次檔

將下列程式碼複製到記事本，儲存為 clean_vmware_reg.bat，然後以「系統管理員身分執行」即可自動清理所有已知的 VMware 相關註冊表項目：

@echo off
cls
echo "flag" >> %windir%\system32\test.log
if not exist %windir%\system32\test.log (
    cls
    echo 請右鍵使用管理員身份運行！！！
    pause
    exit
)
cls
echo. 確認進行清理？
