Why I can't able to use the Rstudio software neither installing or uninstalling both latest or previous versions. I am using free version in windows 10 PC, I am not even able to click anything there after installation so there is no question of sending "output from the script diagnostics". Please other R community users and @discobot help me.
Try changing to software rendering, you can change it by holding the Ctrl key while opening RStudio, then you should see this menu and change the "Rendering Engine" to "Software".
Thank you for your suggestion I will do it. and let you know what will happen.
