I've tried downloading Photoshop 4 times now on Windows 10 HP Laptop and the install is always giving me an error when trying to open.
I had no problems with Light room, the error is as follows...
The code execution cannot proceed because MSVCP120.dll was not found. Reinstalling the program may fix the problem.
What do I need to do?
option 1 is install MSVCP120.dll as windows 10 doesn't use it anymore but you can go back to it
option 2 is upgrade your software to something that is Windows 10 ready... imo this is the better bet in the long run but its your system
Short answer: It's a Windows problem. You need to update the MS Visual Studio C++ libraries.
