Error with installing ARM-Keil packs

Hello! I'm trying to download some packs to use with hardware on the pack installer for the ARM-Keil simulator however, every time I try to install the pack "Keil::STM32L4xx_DFP" I get an error message that reads: 

E: the specified CMSIS Pack Root directory does NOT exist! Please take a moment to review if the value is correct or create a new one via `cpackget init` command 

Cannot download " General error

Could anyone help me resolve this issue? I'm not finding helpful answers for my specific issue online and would really appreciate the help!
