Unable to Install Updated DFP Package for L4/F7/H7 Board in Keil MDK

I am trying to update the Device Family Pack (DFP) for STM32L4xx_DFP, F7, and H7 in Keil MDK, but I am unable to install versions 2.7.0 or 3.0.0. The default installed version is 2.6.2.

Steps I Tried:

• Opened Pack Installer in Keil MDK.
• Selected STM32L4_xx DFP and tried to update to 2.7.0 or 3.0.0, but the installation failed.
• Also attempted to update the DFP for STM32F7 and H7, but faced the same issue.
• Downloaded the .pack file manually from Keil’s website and tried installing via "Import", but it didn’t work.
• Verified my Keil MDK version ( µVision V5.26.2.0).

Question:

Has anyone else faced this issue? How can I successfully install the updated DFP package?
