I've received this error on Windows 7 machines.  It is fixed by right clicking on eQUEST, going to Compatibility tab, and running the program in Compatibility Mode for Windows XP Service Pack 3.  I assume Vista has a similar feature.<div class="gmail_extra">

<p class="MsoNormal"><font color="navy" face="Arial"><span style="font-size:10.0pt;font-family:Arial;color:navy">Everyone, we are having issues getting a
particular eQuest Wizard model to run on a certain set of computers. We can run
this model in eQuest 3.64 and 3.63b on other Vista 64 bit operating system computers
in the office, so we are pretty sure it is not a <u></u>Vista<u></u>
problem.  The attached file is a computer that successfully runs the
eQuest Wizard model. The JPEG image shown below shows the specs for a computer
that does not successfully runs the eQuest Wizard model in either 3.64 or
3.63b. Both computers use <u></u>Vista<u></u> and both are
64 bit operating systems. We have discovered that the error message occurs on
another computer we have in the office with the same parameters as listed
below. Does anybody know what is going on and how do we fix it? Waiting for
eQuest 3.65 to maybe fix the problem is not a successful option.<u></u><u></u></span></font></p>
