The SoftClient SwyxIt! is only executable under x86 compatible processors.
A usage on a Microsoft Surface Pro X with a SQ1™ or SQ2™ARM processor is therefore not possible, because the corresponding frameworks and libraries are not available for the ARM technology.
An automatic conversion of x86 code into ARM-compatible code, as is provided for example by Apple with Rosetta for the M1 processor, is currently not available. Whether this will change in the future is currently unclear.
Of course, the same applies to all non-x86-compatible processors and devices, such as Windows 10 for ARM on a Raspberry Pi 4.
