i downloaded krita, but it wont open, i've tried opining it from the task bar, restarting my computer, i even downloaded the 32bit version after the 64bit didn't work. Please help

Which Operating System do you have? Do you have a 32-bit or a 64-bit computer?
Where did you download krita from and what version did you download? What was the downloaded file called?
Did you go through a normal looking installation process after you downloaded it? Were there any kind of error messages during the installation process?

Do you have krita showing as an item in your menus? Did you get a launcher icon on your desktop? What exactly do you mean when you say that you tried opening it from the taskbar? Did it show as a running application on the taskbar?

If you have a 64-bit computer, there's no point trying to install the 32-bit version and that may also cause problems depending on how you try to install it and the settings of your computer.
