How should you proceed if installation of the Microsoft SQL server fails?
Make sure that you proceed according to the installation instructions and the notes in the "Readme" file. Make sure in particular that:
- You are logged in locally.
- Have administrator rights.
- The Windows firewall and virus scanner are disabled.
- The target folder for installation isn't compressed.
The following instructions do not claim to be able to clear all possible installation problems in any event. The instructions can help to provide a solution to installation problems in many cases.
|1||Repeat installation of the SQL server|
A possible cause for abortion of the SQL server installation might be that certain files (DLL) should be replaced. This might mean that you have to restart the computer. This is why you should first try to repeat the installation. If this aborts, leave the SQL server CD in the drive and restart your computer. Once the computer has been restarted, the installation should be continued.
If installation problems continue to occur, proceed with the next step.

|7||Reinstall the SQL server|
Execute the "normal" WinCC installation of the SQL server once again, for example by calling the Autorun program from the SQL server CD supplied. This is always absolutely necessary if the original MS Setups have been executed, so that WinCC-specific settings are entered in the SQL server.
If the Setup aborts again, then acknowledge the error message and restart the computer. For this you leave the SQL server CD in the drive.
