If you see the following errors when installing AI-powered RC Astro tools in PixInsight, it could be that your CPU is not capable of performing neural network computations:

C:/Program Files/PixInsight/bin/BlurXTerminator-pxm.dll
<* failed *>
*** PixInsight API Error: Module: C:/Program Files/PixInsight/bin/BlurXTerminator-pxm.dll
Cannot load library C:\Program Files\PixInsight\bin\BlurXTerminator-pxm.dll: A dynamic link library (DLL) initialization routine failed.: Module load error

In the Windows Event Viewer, you might find error messages like this:

Faulting application name: PixInsight.exe, version: 1.8.9.1, time stamp: 0x6284c71b
Faulting module name: tensorflow.dll, version: 0.0.0.0, time stamp: 0x61118c31 Exception code: 0xc0000005 Fault offset: 0x00000000056b306c

Faulting module path: C:\Program Files\PixInsight\bin\tensorflow.dll

When launching Photoshop-based AI tools, you might see an error like this:

Could not load C:\Program Files\Rc-Astro\StarXTerminator\tensorflow.dll

All of these error messages tend to indicate a CPU that is not suited to performing neural network computations.

Neural networks are an advanced technology that require a modern CPU. Specifically, the CPU must support AVX instructions. CPUs dating before about 2012, and even some modern CPUs for low-power or mobile applications lack this capability. Intel “Celeron” processors in particular lack this support. This is a limitation that doesn’t just apply to RC Astro tools – other AI-based tools will likely not run at all on these CPUs.
