SQL Sever Installation Problems

Can an SQL Server database CD be installed on only one computer? Bachunhong

I bought a single-host SQL Server database disc and first installed it on a friend's computer. But in the installation type, I chose "client tool ", I did not select "server and client tools". Later, I installed the tool on another computer. After selecting the computer name "Local Computer", the following text appeared: "previous ProgramTo install a file that has been suspended on the installation computer, you must restart the computer before running the installation program. "What is the problem?

I have also encountered this problem because I installed SQL server before and deleted it later, but the Installation File of SQL Server is not deleted, which leads to the current reinstallation, the following error occurs: "A previously installed program has created a pending file on the computer. You must restart the computer before running the installer. Unable to proceed. The solution is as follows:
1. reinstall the operating system and then Install SQL Server.
2. You do not need to reinstall the system. The specific steps are as follows:
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.
