### Summary

Updating from 1.6.15 to 1.6.17 is not exactly smooth

### What software is involved?

- Operating System: Win 10
- Cryptomator: 1.6.17
- …

### Volume Type

_No response_

### Steps to Reproduce

I installed 1.6.15 and then, without doing anything else, tried to update it to 1.6.17.

This resulted in an error message along the lines of "Older version of WinFSP already installed. You must uninstall the older version before you can install this one".

According to my OS WinFSP is not installed at all.

I clicked "OK" and the Cryptomator installation carried on as if everything is okay. Is it?!

This is confusing, and it leaves me wondering what the status of Cryptomator is.

### Expected Behavior

Update smoothly

### Actual Behavior

No idea!

### Reproducibility

Always

### Relevant Log Output

```shell
I have not tried, naturally.
```
