I can’t find a normal calculator.exe - where can I get it?

Question

Windows

Winda has always pleased with funny glitches, and a dozen is no exception. For some reason, a beautiful native calculator fell off for me. The funny thing is: when you try to reinstall it from the store, the whole store fell off!
I didn't find a way to fix these idiots (or rather, I found ways, but they didn't work), so I started looking for a separate calculator application that can be downloaded as an executable.
Then I was very surprised, looking at buggy freaks among free calculators that cannot be used at all, especially after the native Windows calculator. Nightmare! It seems like the simplest application, but there is literally no choice.
Advise pliz, throw links or names, and maybe even an exe-file of a native tens calculator (or a way to fix it along with the store).

Answer 1

The old calculator from WinXP works. Specially for the sake of your question, I put it on a virtual machine, then I tore the exe-shnik into the host win10.

Call Microsoft technical support, they are obliged to help you. In the end, you paid them money for this, which means they are obliged to make everything work for you.
