Why is there such a problem:
Mostly in the process of installation, computer restart, crash, blue screen, etc., that is, in the middle of the program installation, computer hardware or software caused by illegal restart, crash, blue screen and so on. This error occurs when you install the program again after you enter the system for the second time.
Illegal shutdown, resulting in part of the temporary folder and installation files under the InstallShield, at the time of installation, you can not cover, you need to empty Nstallshield before the installation of temporary files and installation files. If the secondary installation occurs, the temporary files and installation files are generated. To cause a conflict, an error occurred.
why the normal installation of a program, once again cover the installation can be normal installation, installation midway because of the panic, restart, blue screen and other factors, illegal disconnect installation, then in the second installation will appear this error ?
If the normal installation of the program, will automatically empty the installation of the InstallShield left under the temporary files and installation files, how to prove this statement? When you install 0FFICE2003, check the properties of the system disk during installation, The system disk usage space is greatly increased. After the normal installation of 0ffice2003, the system disk usage space is restored to normal. Because when the Office2003 is installed, 0ffice2003 will automatically generate the installation files and temporary files in C:/Program Files/common files/installshield/. and InstallShield Exactly is also in the C disk, so at this time the system disk use space to gather up. After installation, the temporary files and installation files generated under InstallShield are automatically deleted. So after installation, the system disk use space to return to normal. That's the point. If the C disk uses the remaining space is insufficient, may also cause the error OH.
Workaround:
start running C:/Program Files/common files/installshield/professional carriage return, delete all the files and folders inside, and runtime folder will be prompted not to delete, as long as the Save run All files and folders outside of time are deleted. And then open the program you want to install again, is it OK to install it normally? It's not going to be a bad clue???
