Hi. Yes, this is normal — Lookupper has no control over how long it takes to install OCR languages. It’s entirely handled by Microsoft software and the Windows compatibility tool. It usually takes 10–20 minutes, depending on your computer’s performance.
I’ve tried to find a faster way to install OCR languages, but no luck.
Alternatively, you can install it by adding a new language in Windows System Settings — but it takes the same amount of time either way.
