new OS

[Isaac5EDB]

I want to do a clean installation of windows.

Can I then reinstall LR and PS without any problems?

Does this see this new installation as the 1st installation and can I still install it on a possible 2nd PC?

1. Which new OS?

2. What exact version of Lightroom and Photoshop? (Or is it the Creative Cloud Photographer Plan subscription?)

Yes you can. You have to make a backup of your personal data and settings.

Please note that you logged out from this installation before you deinstall it.

If you don't have another computer with an installation, yes.
