tinus added on 2026-05-11 09:52:38: (text/x-markdown) <verbatim-8acd8cd69f55d47f3412>My new PC has a Qualcomm Snapdragon Processor. I have installed the .NET 10 Framework for ARM architecture. This is not recognized by ZPreview. So, I installed the "self-contained" version. Howver, this crashes:

tinus added on 2026-05-11 09:53:54: (text/x-markdown) <verbatim-f7760fe91cf76f58f446>Does ZTreeWin run on a Snapdragon? I didn't think it would, so I configured ZPreview to be built for win-x64 only. I didn't expect the Windows Preview Handlers to work there either, but then, who knows...

Looking at the CLSID, it would appear that you do have the PowerToys preview handler(s) installed...

I can set it to build for 'AnyCPU', but I don't know how that would impact the COM interfaces those require. Or I could disable the Windows Preview Handlers in that case.

Do you get the same error when you select one of the built-in handlers, like Image, Text or Hex?</verbatim-f7760fe91cf76f58f446>

yes, it's running windows64, and Ztree is fine (pobably using the built-in emulation)

> Do you get the same error when you select one of the built-in handlers, like Image, Text or Hex?

The error comes immediately after invoking ZPreview from within Ztree</verbatim-5ce43b216caf69a2591b>

github-copilot/gpt-5.4 (claiming to be tinus) added on 2026-05-11 10:51:17: (text/x-markdown) <verbatim-d52cb560bb0f76ac5f51>Implemented in [](f8dac4fd8677) on [ticket-d2d9e5a5f3-snapdragon-startup-crash](/timeline?r=ticket-d2d9e5a5f3-snapdragon-startup-crash). Added graceful handling for architecture-incompatible Windows preview handlers and updated the ZPreview release/docs flow to publish win-x64 and win-arm64 archives. I could build ZPreview, build ZPreview.Tests, and publish win-x64/win-arm64 packages on Linux, but I could not run the WinForms/Desktop tests or verify COM preview activation on Windows ARM64 here, so leaving this in Review.</verbatim-d52cb560bb0f76ac5f51>
