● Illustrator ●

將以下表單內的內容複製起來
Windows Registry Editor Version 5.00 <br> [HKEY_CLASSES_ROOT\CLSID\{0C5B0CED-206B-4c39-B615-0EB23C824612}] <br> [HKEY_CLASSES_ROOT\CLSID\{0C5B0CED-206B-4c39-B615-0EB23C824612}\InProcServer32] <br> @="C:\\Program Files\\Common Files\\Adobe\\Shell\\AIIcon.dll" <br> "ThreadingModel"="Apartment" <br> [HKEY_CLASSES_ROOT\CLSID\{0C5B0CED-206B-4c39-B615-0EB23C824612}\MiscStatus] <br> "IconBits"="16" <br> [HKEY_CLASSES_ROOT\.ai\ShellEx] <br> [HKEY_CLASSES_ROOT\.ai\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}] <br> @="{0C5B0CED-206B-4c39-B615-0EB23C824612}" <br> [HKEY_CLASSES_ROOT\.eps\ShellEx] <br> [HKEY_CLASSES_ROOT\.eps\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}] <br> @="{0C5B0CED-206B-4c39-B615-0EB23C824612}" <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.EPS\shellex] <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.EPS\shellex\IconHandler] <br> @="{0C5B0CED-206B-4c39-B615-0EB23C824612}" <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.EPS\shellex\PropertySheetHandlers] <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.EPS\shellex\PropertySheetHandlers\AIPage] <br> @="{0C5B0CED-206B-4c39-B615-0EB23C824612}" <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.11\shellex] <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.11\shellex\IconHandler] <br> @="{0C5B0CED-206B-4c39-B615-0EB23C824612}" <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.11\shellex\PropertySheetHandlers] <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.11\shellex\PropertySheetHandlers\AIPage] <br> @="{0C5B0CED-206B-4c39-B615-0EB23C824612}" <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.12\shellex] <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.12\shellex\IconHandler] <br> @="{0C5B0CED-206B-4c39-B615-0EB23C824612}" <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.12\shellex\PropertySheetHandlers] <br> [HKEY_CLASSES_ROOT\Adobe.Illustrator.12\shellex\PropertySheetHandlers\AIPage] <br> @="{0C5B0CED-206B-4c39-B615-0EB23C824612}"</body> <br> </html></body> <br> </html></body> <br> </html></body> <br> </html>

開啟筆記本，儲存成*.reg
接著，執行這個剛剛儲存的*.reg
這樣就能夠預覽到AI檔！！

如果還有問題，請到以下網址下載aiicon.dll
http://www.dlldump.com/download-dll-files_new.php/dllfiles/A/aiicon.dll/11.0/download.html
將該檔放置到C:\Program Files\Common Files\Adobe\Shell\裡面，覆蓋原檔

如果沒有psicon.dll檔案，請至下面下載... (基本上應該會有=_=)
http://www.dlldump.com/download-dll-files.php/dllfiles/P/psicon.dll/download.html
將該檔放置到C:\Program Files\Common Files\Adobe\Shell\裡面

方法二: 下載 psicon.dll
放到 D:\Program Files\Common Files\Adobe\Shell 裡
