Windows - LibreOffice Installer slow on computing free space

Operating system: Windows 10 x64 - 64Bit
Libreoffice Version: LibreOffice Still Branch - 4.4.5.2

Hello LibreOffice team and community.

I am having problems with LibreOffice and it affects past Windows versions as well.

The installer takes an eternity computing free space when the installer starts up and when using the Custom option and selecting and deselecting components.

Can this be fixed please. Surely 2 to 3 minutes is a bit excessive to calculate free space on a drive?
