SQL SERVER 2000 is installed when the following tips:
"Before the installation of a program already installed on the computer on to create a hang in the file operations. Run the installer must re-Qidong Jisuan Ji Cheng Xu Before ."
Follow the prompts to restart the computer, then install, still appears the same prompt. This is because the installation program in the previous installation in the system registry left some information, cause can not be installed. Delete the following key information to install:
In the Run window, enter regedit, open the Registry Editor, in the HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Control \ Session Manager found PendingFileRenameOperations, remove the key, close the Registry Editor. Re-install SQL Server 2000, this time, you can normally expect to enter the installation interface.
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager is stored in a snapshot of the current system session, while the PendingFileRenameOperations record is a file name change is not successful operations, SQL Server2000 installation may use this key to record the installation process temporary files on the operation of the installation process if the SQL Server2000 start key when it was found that the existence of a setup program on it that did not complete, so refused to continue the installation process itself. And in accordance with the truth, no one had rewritten the procedure for this key should be at the end of time or the system is rebooted this key is deleted, but if for some reason for this action not taken, then naturally give out any wrong SQL Server2000 conclusions.
The key is to setup pending projects, as long as the application to find the corresponding removed on the line.
