Photoshop 2015 doesn't have features

Unfortunately @Ranjisha Sengupta  the provided specs do not meet current Photoshop minimum requirements.

6 GB ram is too low - the minimum is 8 GB.

I would also suggest you check your graphics card if you are running an AMD a8, the graphics card could also be below minimums.

I would not upgrade your Photoshop until you can meet or exceed the minimum requirements.

Hi there,

Thanks for reaching out.

Photoshop 2015 is a very old version. Features like a custom wrap, object removal, and many others are unavailable in this version.

Would you mind updating the software to the latest version to get all the features?

To update Photoshop to the latest version, check this: https://helpx.adobe.com/photoshop/kb/uptodate.html#:~:text=How%20do%20I%20check%20for,See%20Update%20Creative%20Cloud%20apps.

Thanks.
