Unable to find ipopt.exe wheh downloaded using conda forge

Question

I have just downloaded anaconda from it's web page for windows. H have installed pyomo using conda forge, also ipopt. However, when I run a pyomo program which uses ipopt as solver, I get the following error.

    WARNING: Could not locate the 'ipopt' executable, which is required for solver
    ipopt
Traceback (most recent call last):

  File "C:\Users\UX490U\informe_1\modelo_avion_bueno\07_10_2020_raw_pp_comparison\12h_horizon\2018_12h_jan_oct\noviembre\ECMWF\nov_EC.py", line 536, in <module>
    results = opt.solve(modelA,keepfiles=keepfiles,tee=stream_solver)

  File "C:\Users\UX490U\anaconda3\lib\site-packages\pyomo\opt\base\solvers.py", line 516, in solve
    self.available(exception_flag=True)

  File "C:\Users\UX490U\anaconda3\lib\site-packages\pyomo\opt\solver\shellcmd.py", line 118, in available
    raise ApplicationError(msg % self.name)

ApplicationError: No executable found for solver 'ipopt'

I have gone to solver\shellcmd.py and I have read it, I see the line

from pyomo.opt.base.solvers import *

But I don't know if this is what should look like.

I need help to understand what is going on and what I can do.

I had a similar issue with another solver. The solution found here to add the .exe location to your sys path worked for me https://stackoverflow.com/questions/32316069/pyomo-cant-locate-glpk-solver — cookesd, Nov 17 '20 at 23:09
Thanks for the answer, but I cannot find the .exe location. When I download it, I have searched using the file explorer, but there is no ipopt.exe — slow_learner, Nov 18 '20 at 17:18
Maybe this issue is relevant: https://github.com/conda-forge/ipopt-feedstock/issues/55 — moorepants, Nov 27 '20 at 10:38
@slow_learner I have the same issue, and have been at it for some time now. Had you found a solution you remember ? (ik, it's been 3 years ... ) — Falanpin, May 23 '23 at 11:11
