The unable or cannot register or set file associations correctly in Windows Vista problem is caused by the UAC (User Account Control) security feature.在無法或不能登記或設定文件關聯正確，在Windows Vista的問題是，所造成的UAC （用戶帳戶控制）的安全功能。 UAC prevents any program or process from accessing, modifying, changing or editing the protected system registry, if the the program or process is running in low privilege or low priority mode without full administrator privilege, which has been suppressed by UAC.的UAC阻止任何程序或過程，從訪問，修改，改變或修改受保護的系統註冊表，如果該程序或進程正在運行在低特權或低優先模式，沒有完整的管理員特權，這已受到抑制的UAC 。
Some error message that may be prompted including “An error occured while changing file type associations.一些錯誤訊息，可能會提示包括“發生錯誤，而改變文件類型關聯。 If you are using a limited account, please contact your system administrator.”如果您使用的是有限的帳戶，請聯絡您的系統管理員“ 。
The UAC restriction can cause file type and file extension association to fail during the setup installation process, and also when user attempt to registry the file association from within the program itself, it the setup installer or the program is not running explicitly in high priority elevation mode with full administrator privileges.有關的UAC的限制，可能會導致文件類型和文件擴展名協會要失敗的安裝過程中安裝過程中，也當用戶試圖登錄檔案協會從內部程序本身，它的安裝或安裝程序沒有運行，明確在海拔高度優先模式與完整的管理員特權。 Thus, after attempting to associate file type of some file extensions such as .JPG to third party image editor, the JPEG image will still be opened by default Windows tool such as Windows Photo Gallery.因此，企圖後，聯想到的文件類型的一些文件擴展名，如。 JPG格式，以第三黨的圖像編輯器， JPEG圖像仍然會開幕默認的Windows工具，例如Windows照片庫。
Thus, to fix the file association error by some programs, there are two workarounds.因此，修復文件關聯錯誤的一些程序，有兩種替代方法。 First resolution is to run the program (or the setup installer if file association is done during installation process) in high level priority elevated mode with no UAC restriction.第一項決議是運行該程序（或安裝Installer如果文件關聯是在安裝過程中）在高層次的優先高架模式的UAC沒有任何的限制。 To do so, right click on the program shortcut or program executable, then click on Run as Administrator .這樣做，右擊該程序的快捷方式或可執行程序，然後按一下就以管理員身份運行 。 Second solution is of course, to第二個解決辦法，當然是， disable and turn off UAC禁用和關閉的UAC once and for all.一勞永逸的。
