The Management by Statistics 3 uses Microsoft SQL Server to manage your information in database files. SQL Server was choosen because of its robust features and rugged operations. It is capable of handling hundreds and thousands of users on a routine basis, while at the same time being compact enough for single computer operation.

There are times when a computer either does not have the features required to run SQL Server or one or more of these features has been disabled. In these cases, the installer for the Mastertech Database Manager will instruct you to install SQL Server manually. See the link below for instructions on how to install SQL Server manually.

Features of Windows required by SQL Server are normally part of Windows. It is best to ensure you have done all updates for Windows before installation.

Error 2147749896 (0x80041008): The Windows Management Instrumentation (WMI) features of Windows are not functioning properly or are disabled. WMI is a part of Windows and, by default, is enabled and operating on Windows computers.
To enable WMI, do the following:

1. Right click on Computer (Windows Vista or Windows 7 or Windows Server 2008) or My Computer (Windows XP or Windows Server 2003), then click Manage.
2. Expand Services and Applications, then click Services. A list of Services installed on your computer will be listed on the right-hand panel.
3. Scroll down to Windows Management Instrumentation and right click on it. Select Properties.
4. Change the Startup type to Automatic, then click the Start button. Click Ok.
5. If WMI will not start or if it is already started but you still get this error, then WMI itself will need to be debugged. See the following links for information on how to do this.
       See Microsoft article http://msdn.microsoft.com/en-us/library/aa394603(v=VS.85).aspx. As mentioned in this article, other errors in your Windows can show up as errors in WMI. Do a search for the error you receive when attempting to start WMI.

Error 2227047362: Your computer needs to be restarted. This situation can occur where other software or updates have been installed or uninstalled and required the computer to be restarted by the install or uninstall actually completed. SQL Server will not install on a computer that is waiting to be restarted from earlier install or uninstall activity. The solution is to reboot the computer, then do the installation.

Error 2226323457: This problem occurs because the Network Service account does not have permissions on the following folder: C:\Documents and Settings\NetworkService\Application Data\Microsoft\Protect.

  In addition to those causes we have found that this error can be caused on a computer where the user is not an administrator.

If you have disabled features of Windows in the past these may have to be reenabled. The manual installation will inform you of what needs to be done.
