You are quite correct. To run a Windows program on Android you need to load a Windows emulator. I have tried Winlator but it did not run Sidekick.exe for me. There are others but most seem to concentrate. on 64 bit programs. Exagear is rated the best for 32 bit programs but is apparently now discontinued and won't load on my newer version of Android. It seems Sidekick is now confined to PCs, but the good news is that it does run, albeit with occasional hang-ups on opening, on Windows 11.
