酒精120安裝問題 - 酒精

請問各位大大
我的之前安裝的酒精版本過就想要移除掉安裝新的版本
但是試過很多次之後發現
不但沒辦法安裝 連舊版也無法移除
安裝時跳出的系統訊息是:
the feature you are trying to use is on a
network resource that is unavailable.
chick ok to try again. or enter an alternate path to a
folder containing the installation package
'trial_setup.msi' in the box below.
Use feature from:要你選擇一個檔案位置
並且旁邊有OK和CANCLE鈕
點選OK會顯示下列訊息
the path
'c:\XXX~(資料夾位置).trial_setup.msi'
cannot be found. Verify that you have access to this location and try
again. or try to find the installation package 'trial_setup.msi' in a folder
from which you can install the product Alcohol 120% (Trial Version)
似乎是找不到檔案之類的
我已經將酒精資料夾整個移除了
再來就是到開始→執行→輸入Regedit
HKey_Local_Machine/SOFTWARE
把Alcohol Soft整個按右鍵刪除
還是沒辦法安裝
請問有沒有解決辦法?
