1. There are three ways to uninstall from the control panel: iTunes, QuickTime, bonjur, and clear the registry information
all the software that starts with Apple should be uninstalled, and then it must be completely uninstalled
after the uninstall, it can be generally solved by installing it
2.

The unknown error is (Gateway timeout) the server is aware as a gateway or proxy, but did not receive the request from the upstream server in time. The upstream server is down (not responding to the gateway / agent) instead of the upstream server and the gateway / agent being inconsistent on the protocol for exchanging data

in normal channel, it is caused by the requested server sending timeout. The solution is as follows:

1. This problem is completely caused by the slow IP communication between back-end computers. If the web server is hosted by a website, only the person responsible for the website setting can solve this problem. The use of proxy and cache on the network is increasing. As long as one link in a series of computers processing HTTP requests is broken, a 504 like error is easy to occur

2. In case of 504 error, please contact the website official. The website needs to contact Internet service provider (ISP) and web server software provider to check the circulation of IP data transmission between different computers under their control. Due to the irregularity of the right of Internet circulation, this type of error is transient

extended materials:

there are often some problems when using iTunes. For example, you can synchronize software, video, music, etc., but you can't enter the iTunes Store. No page is allowed. Click to display the loading page. When logging in to the account, it shows "unable to complete your request for the iTunes Store, unknown error (- 50)" again, resulting in the inability to enter the iTunes Store

solution:

delete the file of itunesprefs.xml in the computer

the path of this file in win7 is:

C:: (users / XXXX / appdata / roaming / Apple Computer / iTunes)

the path of the file in WinXP is:

C:: < documents and settings < XXXX > application data < Apple Computer < iTunes

XXXX is the computer user name, or the default administrator

after deleting the file, rerun iTunes, which will prompt you to reconfigure. After that, iTunes will return to normal, and you can enter the iTunes Store smoothly

note: this method will restore the original status of iTunes, and the database contents and preferences will be cleared. You can hold down the shift key to open iTunes and re select the database

3.

1、 The reason for the problem of network setting is that you need to manually specify the IP, gateway, DNS server networking mode, and use the proxy server to access the Internet. Check your computer's network settings carefully

2. DNS server problem when ie is unable to browse the web page, you can try to access it with IP address first. If you can access it, it should be the DNS problem. The DNS problem may be caused by the error in getting DNS when connecting to the Internet or the DNS server itself. At this time, you can manually specify the DNS service (the address can be the DNS server address provided by your local ISP, You can also use the DNS server address in other places.)

the details are as follows:

computer common problem solving

1. Unable to automatically identify the hard disk controller

using a non genuine indivial operating system CD, this error is easy to occur when installing the system. The reason is that the hard disk controller driver automatically loaded by the non genuine CD does not meet the needs of the computer itself. In this case, it is recommended to replace the original CD to install the operating system

2. Manually updating the wrong driver

the windows operating system works normally, but manually updating the driver updates the driver of the hard disk controller incorrectly, which leads to this failure. The solution is to enter the Advanced menu of windows system and select the last normal configuration to enter the system normally

However, e to some reasons, the user modified the BIOS settings, leading to the fault of 0x0000007b

4. See if there is something wrong with the network software or network settings. What did you do wrong before the accident? Correct it. If it is caused by unknown reasons, it is recommended to restore the system or re install it
1) if it's a router problem, if it can be used in the past but can't be used temporarily, my own practice is to cut off the power supply of the router and plug it in. I'll see later. If there is one, the factory settings will be restored and the new settings will be available (this is on the premise that the physical connection is correct)
if it can't be solved all the time, it's recommended to call the customer service of the router. They have telephone online guidance. When I encounter problems that I can't solve, it's very useful to consult them. They will give correct suggestions for your setting or operation
2) if it is the problem of broadband itself, first of all, directly connect the broadband cable test. If it is the problem of broadband, contact the broadband customer service to solve it
3) if it is caused by system problems, it is recommended to restore the system or re install it<
how to use the system restore:
System Restore: start / program / attachment / system tools / system restore, click recover my computer to an earlier time, and press next, you will see the dark date on the date page, which is the restore point, Click next to restore (win78 to restore the system, right-click the computer to select properties, select system protection on the right, and restore the system. Just do it step by step. If you have software to restore the system, you can also use software to restore the system)
4) if you turn off the wireless switch, just turn it on. If you use software to connect to the wireless, it's normal that the software is not easy to use and often has problems. There's no better way. Use the router.
5. You open the browser, and then click Tools, Internet Options, connection, LAN settings, under the proxy server "use proxy for LAN..." The best way is to delete the agent fox, not simply put it into the recycle bin. What you deleted before is just a shortcut (just an icon). You should go to the control panel - add a deletion program, find the agent fox, unload it there, and restart the computer.
6. My method:
1, just register a new account with your email
2, use this account to enter
3. In the drop-down list in the upper right corner, you can log out of the new account automatically
