SAS support helped me find a solution. I had to use the code below for my 64 bit version of SAS to communicate with the 32 bit version of excel.
libname dot PCFILES PATH="\\global\shares\Projects\110933\data.xlsx";
I also had to uninstall PC file serve since I had both a 32 bit and 64 bit version installed. I reinstalled 32 bit PC file server and the code above worked.
