application exception

0xC000001D ILLEGAL_INSTRUCTION

The CPU was asked to run an instruction it does not understand — wrong CPU target build, corrupt binary, or a bad patch. Rare on stock retail software; common after incomplete updates or mismatched portable apps.

What to do about it

Reinstall the program from a fresh download.
Do not mix 32-bit and 64-bit plugin folders.
If only one portable build fails, delete it and re-download.

Where you will see this

Windows Error Reporting writes this code into Report.wer files and app-crash minidumps when a program dies but Windows itself stays up. It is not a blue-screen stop code — for those see the stop-code library.

See which module threw this exception

Drop the program's .wer report or crash dump into the app-crash reader — the faulting module is usually the real story. Parsed locally.
