To clear the hard disk space. after the tmp file is deleted, an error is reported when SQL Server 2000 is installed: "A previously installed program has created a pending file on the computer, you must restart the computer before running the installer. "The reason is not found at the beginning. You cannot restart the computer, and you almost have to re-format it.
Fortunately, I found "about SQL installation" through the CSDN forum, and many people encountered the same problem. The answer provided by zhujian is:
Delete the PendingFileRenameOperations sub-key under HKEY_LOCAL_MACHINESYSTEMControlSet001ControlSession Manager in the registry. An error occurred while suspending the file.
Open regedit.exe and find PendingFileRenameOperations pointing to a tmp file. The original problem is that the Temp file is manually deleted. It seems that the Temp file can not be deleted at will.
