2026-10-09 APP 2.0.0-beta48 has been released !
This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster 🙂
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
I seem to be having a few issues with APP not launching for whatever reason, I want to look into this but want to know if there are any application logs anywhere.
Basically I click on the Icon but it never loads, if I re-install over the top of the existing install, it seems to work fine for a while and then goes back to the same behaviour
There's no real logs for the launch I think, you may get some output if starting from the shell (not sure though, sorry). Do you know if any virus scanner or something like that may be causing an issue?
I get nothing from the command like either, really strange, I am using Sophos Anti Virus which has never had an issue with APP before, and would not expect it to work after a re-install either if it was the AV causing the issue, it's doing it again right now, so I guarantee after a re-install it will work 😀
So here's the thing, after a re-install, having APP launch immediately after the install selecting the option to launch it, it launches fine, but then closing the app and trying to re-launch does nothing.
If I un-select the option to Launch APP and then try and launch manually, it doesn't launch. So I am going to install it to another location and see what happens.

Fixed it
When it was originally installed, it was installed as an "Only for me" so it was installed in %appdata%\Local\......
I have just removed completely, and re-installed for "Everyone" and now it works again without issue, I wonder if there was some update that broke this
Interesting as I think that should also work. I'll report this to Mabula.
Hi Simon @stastro,
The shortcut on either your desktop or in the startmenu was probably broken? I mean still pointing to the old installation directory?
