Open DXF2000 file and get a "text import options" window.

Trying to open a DXF2000 file and I get a "Text Import Options" window instead of the scaling window I am supposed to get.   I have followed many other posts here and have installed a new C++ runtime  and tried to regress to AI v. 25.4.1 ( the oldest I have access to with CC)  I am new to AI.  How do I get around this problem?  Screanshots are in reverse order....  Thanks for any help!
