Re: Problem with APCC/APPM with AP1100AE #APCC

Hi Phillipe,

It sounds like you may have installed ASCOM Platform 6.5, which is not backwards compatible with earlier versions and thus breaks APPM.

The solution is to uninstall Platform 6.5, and then reinstall Platform 6.4SP1. The link to this version is here:

Subject: [ap-gto] Problem with APCC/APPM with AP1100AE #APCC

I've been using my AP1100AE for more than one year now without major problems but since one month now I
cannot succeed in making a valid model via APPM.
The symptoms are very big numbers in the APPM table and when tracking or pointing is selected in APCC Pro
I have huge errors, so I cannot do anything and especially not long unguided pauses (one of the main reasons
I'd purchased this mount).
I've tried may times (and lost at the same time very good nights of clear sky) to reinitialise everything but the
problem is always present, I join here the screen copies of my last attempt tonight after a complete reinit, I've
try to make A very simple 13 points model, the process goes well but the numbers seems very wrong ! (the
APCC screen copies show the views before and after the model is entered)
Thanks very much for your help, especially if Ray can have a look into it, I've contacted George and Howard at
AP support but have no answer.

My set up:
SGP Platesolve ASTAP (doesn't work better w/Platesolve2 and slower)
ASI2600MMpro Canon EF L 400mm2.8 @ 800mm FL
