.NET串連Oracle出錯的解決方案【System.Data.OracleClient requires Oracle client software version 8.1.7】

搞了個Oracle伺服器，用MSPetShop串連Oracle，安裝好後，瀏覽卻提示如下錯誤：

【System.Data.OracleClient requires Oracle client software version 8.1.7】

不知道詐回事，Google了一下，原來是安裝目錄的Authenticated Users沒有寫入和修改許可權，具體操作如下：

1. go to oracle installation folder, which is most likely “c:oracleora92”
2. right click and select properties
3. go to security tab
4. find Authenticated Users and select it
5. uncheck read and execute box in the permission
6. re-check read and execute
7. click OK
