Packing unknown error on fresh c++ sidescroller win32

I work with really fresh c++ sidescroller nothing changed. UE 4.15.1 with vs2017 basic installation.

I can pack win64 without faults. On win32 packing i get follwing output log, ending in unknown error.

Anyone some ideas what i can do?

output log:

Hi,

VS 2017 CE Installer do not install 2015 Toolset basically (with only switch on necessary package).
I reinstalled VS 2017 CE manually choosing VS 2015 Toolset. Afterwards I was able to pack win32 too.

Found this information on another forum.
