   Thanks for following up, and sorry OpenCode still doesn't run on your PC.

   I think this is a duplicate of #59461. That issue collects requests to make OpenCode v2 run on older CPUs, and a Node.js-based build that doesn't use Bun has already been suggested there. The crash happens because even Bun's most compatible "baseline" x64 build needs the SSE4.2 and POPCNT CPU instructions, so processors without them get SIGILL at startup.

   Possible duplicates and related issues, ordered from most to least likely:

   • Crash on startup (Error 134 / Missing SSE4.2) #59461: the main thread for supporting CPUs without SSE4.2/POPCNT, including the Node.js build suggestion
   • opencode does not work on old cpu SIGILL error #59522: your earlier report of the same SIGILL crash in the 2.1.4 Linux desktop app
   • Feature Request: Provide Node.js fallback or compatibility mode for older non-SSE4.2 CPUs #60982: a request for a Node.js fallback for older CPUs, closed as a duplicate of Crash on startup (Error 134 / Missing SSE4.2) #59461
   • [Bug]: OpenCode v2 binary crashes with SIGILL (Illegal instruction) on x86-64-v1 CPUs (SSE4.2/POPCNT missing) #60017: SIGILL on x86-64-v1 CPUs (Core 2 Quad) even with the baseline build
   • Problem on old pc #59582: the same crash on a Core 2 Quad. It has a community write-up on rebuilding Bun for Penryn-class CPUs (unofficial).

   To help maintainers see how many people this affects, please add your CPU model (lscpu | grep 'Model name') and OS to #59461 if you haven't already.

   The bot will close this issue as a duplicate in 1 day unless you reply explaining how your problem is different.

   Thanks! This is the same problem as #59522, which you opened too, so let's keep everything in one place. Requests for a build that runs on CPUs without SSE4.2/POPCNT are collected in #59461.

   Closing as a duplicate of #59522.

   We haven't heard back, so I'm closing this as a duplicate of #59461. That issue collects requests to make OpenCode v2 run on older CPUs without SSE4.2 or POPCNT, which is what causes the SIGILL crash. A build based on Node.js instead of Bun has already been suggested there.

   Please follow #59461 and add your CPU model (lscpu | grep 'Model name') and OS if you haven't yet, so maintainers can see how many people this affects. Until there's an official build, #59582 has a community write-up on rebuilding Bun for older CPUs. It's unofficial and unsupported.

   If your problem turns out to be something different, please reply here and we can reopen.
