I want to change to Windows10 from Windows7  

I think that if the upgrade works out fine, it should still work on Windows 10. Your hardware didn't change etc. I would advise to perform a backup of your system first.

Hi Vincent,

My idea is not to do an upgrade to Windows10 but do a clean install so

there will not be anything left on the harddisk.

I have seen a menu that allows me to deactivate APP from a computer.

Should I do that first, reformat the laptop, install W10 and then reinstall

APP again? ( I still have the licensing data received when I bought APP )

Would that be the correct way to do?

Thanks for your help!!

Ah ok, yes then you would need to have the licence at least. If that's the case you can just reinstall APP and activate it again, deactivating shouldn't be necessary as it's the same computer, hardware-wise.

@vincent-mod

Thanks Vincent, that sounds easy enough.

So, reformatting, installing and if needed using the licensing information

supplied when I bought APP should do.

When I do the reinstall of Windows10 I will give feedback in this thread.

I apreciate your help a lot !

Best regards,

Mert

Ps. if you have 3 machines licensed, maybe it's a good idea to at least deactivate 1. Just in case. 😉
