When you write applications that use ADOMD.NET, you must redistribute ADOMD.NET along with your application. To redistribute ADOMD.NET, include the ADOMD.NET setup program, SQLServer2005_ADOMD.msi, in your application's setup program. The ADOMD.NET setup program can be found on the Microsoft Web site. After you include the ADOMD.NET setup program, have your application's setup program launch the ADOMD.NET setup program and install ADOMD.NET.
The ADOMD.NET setup program installs the ADOMD.NET files in <system drive>:\Program Files\Microsoft.NET\ADOMD.NET\90.
