Does 1.7/3.9/4.5 weighted GPA mean that your unweighted GPA was something like 0.7/2.9/3.5?
Many colleges require or recommend some level (typically two or more years) of foreign language study for frosh admission.
However, a possible way to remedy that would be to take foreign language at a nearby college next year, since a year of college foreign language is typically equivalent to two (or sometimes more) years of high school foreign language.
In addition to your GPA issues (which presumably mean that only branch campuses, not University Park, could be reasonable possibilities for admission), Penn State requires two years of foreign language, although they may make exceptions (but if admitted under such exception, you need to take a college foreign language course to graduate): High School Course Requirements: 4-Year Degrees - Undergraduate Admissions
