You are running RouterOS 7 already. However, looking at the package size, with routeros being 6.9MiB and wireless 676.1KiB, it looks like your device is one with the SMIPS CPU architecture. If that's the case, then there was this change made in 7.20:
Hotspot is no longer part of the main routeros package. For 7.20.7, you'll need to download this extra package (133KiB):

Alternatively, click on "Check For Updates" on the right of the screenshot, and the hotspot package should appear grayed out in the list too. and can "Enabled" from there. Please note that the latest long-term version is 7.20.8. So maybe upgrade to that too.
