Ladies and Gentlemen:
Van Kampen Explorer Institutional Trust (the "Registrant"), filed via
EDGAR on April 29, 1999, a copy of Post-Effective Amendment No. 4 to the
Registration Statement on Form N-1A (the "Registration Statement") complete with
exhibits filed therewith pursuant to Rule 485(b) of the General Rules and
Regulations (the "1933 Act Rules") of the Securities and Exchange Commission

In accordance with the provisions of Rule 497(j) of the 1933 Act Rules
