Disable Apps Auto Reopening in Windows Thank you so much for this! This is opposite in my region, and the setting in Windows does not seem to apply to the calculator, I wonder if there is another binary available?

The binary is unmodified. It is the genuine binary file, made by Microsoft. I have no other binary here. Thanks for your response, I realised to my surprise that my format setting was wrong in regional settings. It is okay now, thanks for your work! I'm so relieved to have the calculator back, my life quality just improved by a ton! It does nothing. It could be me, but I tried to download your app again and I still have the same problem.

Did you update the installer? Hmm, I cannot reproduce the issue here! The app runs perfectly. Tried to install it several times both as user and administrator With and without bitdefender protection following tha instructions.. It do not replace the 2in 10 lame calc and it is not to be found in the startmenu or otherwise.

I get absolutely no errors when installing. So in short.. It does work exactly as described in any build of Windows 10, this is confirmed by tens of its users. The only garbage I see here is your pointless comment. Hi there, I have two problems with this. Any ideas? The 2nd issue still stands though. Lo que me gusta es la forma de orden del historial y que se puede modificar, te permite editar un calculo para no tener que poner todos los digitos de nuevo.

Fantastic, just got it working on Windows 10 v The new calculator is awful…the old calculator is awesome. I installed some years ago too and nothing happened. I opened it up from Start Menu and nothing. Process run and then dies, within seconds. Windows 10 Pro x64 I did noticed that everytime I try to open the program a consent. My UAC is disabled.

I have lots of stuff on my desktop open at various times so need to be able to drag it to another position on the screen. Going to stand in a corner and sulk. So there! Unable to find uninstallcalc. Just delete its files and the start menu shortcut. Thank you for the fast reply. Also by files you mean the calc. Thank you for your efforts to make Windows better! It is at the smallest size, I cannot drag edges to enlarge it nor I have active maximize button in the upper right corner.

There is just one to close and one to minimize.. I had to add the shortcut to the start menu manually, and it has an ugly icon. Hi, I install the old calculator, but doesnt run, just not run, I tried to desintal the win 10 calculator, but still not working.

What is the path you have installed it to? What happens if you run the calc1. Hi, the calc looks awesome, but I cannot install it as I do not have admin rights on my notebook. Is there a portable version without installer? Hi, thank you very much! I would like to have a portable version too, for my office computer.

How can I get it? Extract the installer with 7-zip. Place the files as follows. Even if you get this file from an old win7 installation, Windows defender will try to prevent the installation of the mui for some reason. Once installed, you can reenable defender, and it will not bother anymore, even when doing a system scan, but doing an SFC can delete it.

Thanks for keeping this updated. The functionality is great and better than the W10 calc which has gotten even worse over time. Only one problem — the Old Calc is very small on a large monitor or a high resolution or both. The new one is fully resizable and adaptive. I understand that may be near impossible to recreate or code in the old calc — but can we simply get a large size version? The October update really makes this the best online install solution.

Thanks for maintaining it! Your email address will not be published. Skip to content Advertisement. Support us Winaero greatly relies on your support.

This is great, AND the new one still works on my system, so I can use either. Great App Sergey. Keep up the good work. Can you implement silent switch for unattended install? Gives me in You are a brilliant genius, man. Very insteresting. I will look if it is possible to repack it. Bitmanipulation by clicking on the Bits are no longer availabe Any Idea?

Hi Sergey, Thank you for the great work! Works like charm!!! Tried installing on win10 but keep receiving message that it is already installed. I can both calc.

You move it by dragging the title bar. I can see both calc. Or maybe an MSI file? Loving this. Even the calc shortcut SideWinder X4 has by default opens it. Good job! If you can avoid the Anniversary Update, do so…. Sergey, you made my day. Finally I can recover my lost productivity. Huge thanks for the port! Worked like a charm. I have Windows 10 Pro version Muchas gracias. La calculadora que trae Windows 10 me dejo de funcionar y con esto recupero la funcionalidad.
