1. Check that (Program Files folder )/ATI Technologies/ATI.ACE is empty (檢查Program Files/ATI Technologies/ATI.ACE資料夾是空的)
2. Check (Windows folder)/Assembly folder to see if there's any files with Public Key Token of "90ba9c70f846762e" (Sort by Public key token to get a easier view). All these tokens should be uninstalled by right clicking and uninstalling. (檢查Windows/Assembly資料夾底下的"公開金鑰語彙基元"中有沒有"90ba9c70f846762e"這個檔案, 如果有,按右鍵把該檔案解除安裝)
3. Check that (Document and Settings)/(User)/AppData/Local/ATI/ACE is empty (確認Document and Settings/(User,通常是你的登入帳號名稱)/AppData/Local/ATI/ACE底下是空的, Appdata是隱藏資料夾,要先關掉隱藏)
