Welcome to TalkGraphics

I have not used Corel in many, many years, but there might be an icon on the property bar that will open the axillary applications. Also you can open the folder in which Corel resides (usually C:Program Files (x86), find the PhotoPaint.exe (or whatever the executable file is called), right click on the file and select Pin to Start and/or Pin to Taskbar, then you can launch it independent of CorelDRAW.
