We recommend installing TDO during our technical support hours (0530-1730 Pacific). We are available at if you have any questions or need any assistance.

Step 1 

Download files from the site:

  • SQL2008Express.exe or SQL2008ExpressX64.exe

Note: Please make sure that you delete any existing version of SetupMSDE.exe from your TDO Builds folder. TDO on x64 server requires SQL 2008 Express, and there should not be any SetupMSDE.exe file present during the server installation. 

Step 2
