Second, modify the environment variables to avoid program installation failure When users install some applications in Windows XP system, there will be an error that the system can not find the path, resulting in the installation failure.

Name \\LocalSettings\\Temp", if the user name is "Zhou Jin", then the user variable used is "D:\\Documents and Settings\\周进\\LocalSettings\\Temp"; in general, when running the application software When installing the program, the installer will extract the files into this directory, but some installers do not support or support the path method containing the Chinese name. If the user establishes the Chinese user name in Windows XP system. , then the installer will see the error of not finding the path as shown. Since there is a case where the installer does not support the path of the Chinese mode, then we can avoid the problem by modifying the user variable mode of the user to a directory that does not include the Chinese mode. The specific modification method is: Click the "Start" menu, right click on the "My Computer" icon, select the "Properties" command from the right-click menu, open the "System Properties" dialog window, click the "Advanced" tab Card, click "Environment Variable" in the "Advanced" settings page, enter the "Environment Variables" setting window, you can see that the user variables TEMP and TMP are displayed in the "User User Variables" list box at the top of the window. Set the situation, the user can click the "Edit" button here to modify the variable values of TEMP and TMP, change the variable value from "%USERPROFILE%\\Local Settings\\Temp" to "D:\\Temp", after the modification is completed Click the "OK" button to exit. Restart the Windows XP system to apply the modified environment variables. At this point, when you run the installer again, the error of not finding the path shown in the figure will not appear.
