SYMPTOMS
When you attempt to install Microsoft Project Central with the Install Now option, you may receive an error message similar to the following:

You can not use the Install Now setup option since Microsoft Data Engine (MSDE) is already installed on your machine. Please choose the Custom setup option.



CAUSE
This issue can occur when you already have Microsoft Data Engine (MSDE) or Microsoft SQL Server installed on your computer. Microsoft Project Setup attempts to automatically install MSDE. If a database engine is currently installed, Setup cannot continue.



RESOLUTION
To resolve this issue, use one or more of the following methods.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Method 1: Create a Default Database and Table Installation for SQL Server
NOTE: Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

 Insert your Microsoft Project 2000 CD-ROM. Click Start, point to Programs, and then click MS-DOS prompt. At the command prompt, type cd to open the CD folder, where   is the letter of your CD-ROM drive. To run the script that creates the Microsoft Project Central Project_CentralDB database and tables, type the following

osql -U  -P password -i Crttable.sql

where  is the name of the database service account (sa by default). NOTE: The parameter letters U, P, d, and i are case-sensitive.

 Press ENTER. To create the default records in the tables, type the following

osql -U account name -P password -d db name -i Insdefsq.sql

where db name is the name of the database.</li> Press ENTER.</li> To create the default values in the records, type the following:

osql -U account name -P  -d database name -i Insdefsi.sql

</li></ol>

Method 2: Uninstall MSDE and Run Project Central Setup
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
