Hi there,

I faced with follow problem:  
I have the Homey Pro 2019 and I am using Windows 7 SP1, Nodejs version 16.20.1 installed and Homey CLI version 3.0.2.  
I was able to create a Homey app and install it on the Homey today morning 🙂 But right after that I tried to create and install one more app. After calling homey app install I’ve received the error `string.replace is not a function` and no more logs.

Maybe someone already faced with such problem and have a solution? What does it could be?  
I am aware that I should be updating my OS and use newer versions 😃

It’s difficult to say exactly, but it’s likely caused by a dependency of `homey` that is “too new” for your environment.

Perhaps it’s possible to revert back to an older version of `homey` (`npm install homey@2`), although that might cause other issues.

It’s super strange and don’t ask me how I came to this, but…  
in folder figures(which is in homey → node\_modules folder) I found some condition for unicode symbols  
`const figures = platform === 'win32' ? windows : main;`

changing `win32` to `win64` solved the problem  
still…it’s temporary solution, but at least it works 😃

Strange, since `win64` isn’t supposed to be a valid value according to the [Node.js documentation](https://nodejs.org/api/os.html#osplatform) 😅
