When you install sqlserver2000, the following error occurs: "A previously installed program has created a suspended file on the installation computer. You must restart the computer before running the installer "error

I installed SQL server before and deleted it later. Now, the following error occurs:ProgramInstall a file that has been suspended on the installation computer. You must restart the computer before running the installer. Unable to proceed.

Please refer to the online materials to get it done. Steps:

1) Add/delete programs to completely delete SQL Server.

2) Delete the SQL Server Directory that has not been deleted.

3) Open the Registry Editor, find the pendingfilerenameoperations project in HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager, and delete it. In this way, you can clear the temporary installation project.

4) Delete the SQL Server-related keys in the registry:

HKEY_CURRENT_USER \ Software \ Microsoft SQL Server folder

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft SQL Server folder

In fact, it is estimated that only step 1 can be done, so that you can clear the installation of temporary projects. I did this by leaving for 1, 2, 4, and 3. Therefore, estimation 3 is the most critical.
