I been installing Windows on my new MacBook Pro 13" 2017 Touchbar (MacOS Sierra) but I have been stuck because I get the error Windows support software could not be saved to the selected drive
… I tried installing it using a 16gb USB stick (MSDOS fat32) and no USB since my MacBook can install Windows even without USB flash drive (as mentioned by apple in their website.) Can someone help me with these problems?

Cause
Apple allows Windows Installation, by first copying the entire ISO into a temporary storage area. Most of the time it works, because there is enough space available.
When we use a larger ISO, like the 32-bit + 64-bit Windows ISO, it requires about 6.5 GB just for the storage, let alone uncompressed files usage. Apple tried to download Windows support software onto that partition. This is where the issue happens. The package requires at least 1 GB, and it would not get it because of the ISO.
Solution
Use the 64-bit ISO (3.5GB) instead of the 32-bit + 64-bit Windows ISO for a x64 MacBook (all current generation ones)
Use the 32-bit ISO (3.5GB) instead of the 32-bit + 64-bit Windows ISO for a x86 MacBook (2011 etc.)
