Photoshop couldn't work

[Sei83]

  when I try to open Photoshop which I just downloaded, a pop up comes and says: couldn't run. I did uninstall and re-download,but it didn't work as well. even tried to open it from Windows C. I don't know what to do.

Hi @Sei83 did you install Photoshop on your C: drive (same drive as System and user profile)?

[Sei83]

Hi, thank you for reply. How can i know if it is in the same drive as user profile? There are 3 users on C: now. I actually created a new user on my pc, and Photoshop works there. You think i am trying it on wrong users or something?

That is installed in the right location.

If Photoshop works on one profile and not another the issue is with permissions on that user profile and not a Photoshop issue. Check to make sure the user account with the error is an admin or has permissions same as the account that is working.

Oh I understand now. Just changed the download location as the user that Ps working. will try to install again soon. Thank you in advance, sir.

Do you logged in as an Administrator or an user with Admin rigths? Do you have Photoshop installed with Admin rights?

As far as I see in yourt screenshot it seems there are problems with access rights.

I did try to run as an administrator.  and also i changed to install location. and newest update: still doesn't work. I don't understand what is the difference between two users. the latest installed Photoshop works there again.
