'intcalc.sty' not found

[SofieVdE]

Hi,

I am just starting with the template and trying to compile it in Texmaker.
I always get the error "LaTeX Error: File `intcalc.sty' not found.Type X to quit or to proceed,or enter new name. (Default extension: sty)Enter file name:! Emergency stop. \RequirePackage{intcalc}[2007/09/27]" and this makes that I can't compile the file.

I get this error with the empty version of the template, as well as the thesis of an old colleague, which should work (it works on his computer without any problems). In both files, the error is at the same line (1196, which is way too big to make sense I think...)

Does anyone has experience with this or knows what could help? Thanks!
