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 purchased a renter's license, downloaded and installed the latest version of APP. On first run APP asked for my license key. After that the program did not load as usual. there is an APP process running, but the program no longer loads. I've uninstall and reinstalled, even tried the previous version and nothing. Please advise....
Checked the event log and it shows an error "program compatibility" not sure if that helps...
Hi dariv @dariv,
Thank you for sharing the issue. I will do my best to get this solved as quickly as possible 😉
Can you asnwer the following questions? It should help me in determining what the issue is.
Would you know which APP version you were running before you upgraded to the Renter license?
On which Windows version are you?
Did you install APP in the default location on the file system, or did you specify an alternative?
Have you tried a much older version, to see if that does work ?
Do you have a Java Runtime installed on the system?
KInd regards,
Mabula

Thank you @dariv for all information,
Have you checked if security software on your computer is blocking APP from starting normally?
Another user could not start APP on Windows, because AV/Security was blocking the application:
https://www.astropixelprocessor.com/community/windows/1-072-windows-64bit-app-wont-start/
Kind regards,
Mabula
I have trend micro security agent running.
It doesnt seem to be blocking anything from what I can see in the log file
Checked the event log and it shows an error "program compatibility" not sure if that helps...
@dariv, to be sure, can you post a screenshot or the exact message that you see in the event log?
I have trend micro security agent running.

Okay, to be sure, can you try if things are different when Trend Micro is disabled ?
Another way to trouble shoot is to try to load APP from the commandline since you have a Java runtime installed:
- Can you open a command promtp by running cmd.exe
- navigate to the installation directory, the default on windows 10 would be: C:\Users\[your username]\AppData\Local\AstroPixelProcessor
- execute from the commandline: java -jar "app\AstroPixelProcessor-out.jar"Â Â Â
Check this screenshot:
Please note, APP needs to run in a 64bit Java Runtime (JRE). Yours probably is 32bits, this is no problem to test now if we can start APP.
I tested it with a 32bits JRE as well:
Please let me know what happens and share the output of APP on the commandline.
Kind regards,
Mabula

Dear @dariv,
So this shows exactly the same as in my screenshots, right?
These are normal warnings from a library that APP uses. These are not errors.
To me this indicates that there is no problem with starting the application on your computer as far as APP is concerned. Therefore the problem is not in APP I think, but on the Operating System level.
When it is started, you can see the process in the task manager, right ? Somehow, the Graphical User Interface is not showing so I think we need to focus on that to solve this issue.
Have you checked the graphical drivers ? Perhaps you updated them recently?
Kind regards,
Mabula
The process loads, "AstroPixelProcessor.exe"
No GUI
Â
Hi @dariv
How about your graphical drivers? Did you update these recently?
Maybe it's best that I look on your computer to solve this using teamview or perhaps other screen sharing software?
Mabula
I've tried different drivers after it would not load.
We can try teamviewer, but I will not have the computer available until 4 hours from now
Hi @dariv,
Okay. Can you send me an email when you are ready to support@astropixelprocessor.com ? I will be waiting.
We can also communicate with skype perhaps? Do you have a skype account?
Mabula
Hi @dariv,
Just to summarize my testing on your system:
The issue is the the OpenGl library deployment (the jogamp..... process) can't complete somehow.I suspect this is due to some security software/rule/setting which has been set on your computer.
I will investigate 2 possible solutions to solve this:
1) ask the opengl library devs if they know the issue and possible fix
2) update the library and or change the library deployment strategy
Kind regards,
Mabula
Mabula,
thanks again for taking the time to investigate this issue!Â
Any update on this issue?
Hi @dariv,
The developers of the OpenGL library have confirmed that the issue is caused by security software on your machine.
http://forum.jogamp.org/Jogamp-fat-jar-not-deploying-on-a-Windows-7-64bits-machine-td4039604.html
A paranoid virus scanner prevents it from doing its job. Please try to disable the automated native library loading and manage the Java library path as indicated in the JOGL user's guide.
I proposed to replace this mechanism by a call to a Java API available only in Java >= 1.8 but if the virus scanner still prevents the loading of the extracted native libraries (DLL under Microsoft Windows), the only way to solve this problem will consist in disabling the virus scanner and on the long term to report this false positive to the software publisher of this virus scanner.
I will try to release the next version of APP with a different mechanism to install/load the libraries which hopefully does not trigger the security software/rule on your machine.
Do you have admin rights on your computer? Or is is a machine from you employer perhaps?
Kind regards,
Mabula
The machine in question is my company supplied work laptop, so I can't "unblock" the issue. I have a computer in my observatory that runs APP without issue.
Hi @dariv,
Okay, the developers have notified me of another version of the library that isn't using the self-extracting archive, like the older APP versions that used an older version of the library, that did work, right?
I will try to release the new version as soon as possible 😉
Mabula
yes, the older version worked on this machine.Â
Thanks!
