Some of my packages are not recognised by TexStudio (examples: pdfpages, mathtools, ramsstyle and so on), but most of the packages I use are recognised.
I have installed all of these packages with MikTex 2.9 (even tried to reinstall them), but still TexStudio won't recognise them. This is getting tiresome since I really need to use pdfpages to include a PDF to my document.
Is there any way for me to check if the packages are installed, and if TexStudio is actually connected to MikTex? I also tried to install some new, random packages with MikTex but they were not recognised either.
I don't know if I checked the "Install on the fly" option when I installed MikTex (was and still are fresh in the Latex game).
Any help is much appriciated!
