Probleme photoshop Cs5

Is what your seeing your desktop in the blank area?

It could be in photoshop cs5 you need to turn on the Application Frame by going to Window and clicking on Application Frame.

'it is too old but is still sold on the net with 1200 euros there is something wrong'

No legitimate version of CS5 has been sold for years. Anyone selling it now will be selling an unlicenced copy.

What happens if you check Windows > Application Frame?

But these are not official licenses. I would keep my hands off it.

Please try to disable the option to "Use Graphics Procesor" from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.

If it helps, you can check out the steps suggested here:  https://helpx.adobe.com/photoshop/kb/troubleshoot-gpu-graphics-card.html

If the issue persists, you can try to reset the preferences of Photoshop using the steps described here:

Preferences in Photoshop (adobe.com)

Please backup your settings before resetting the preferences. You can check:

Migrate presets, actions, and settings (adobe.com)

If this all doesn't help, we need more informations aubout your system. Maybe you can post your Photoshop system info. In Photoshop goto Help > System Info and hit the copy button. Then paste the entire informations into this thread.
