While installing Skype for business 2015 on windows server 2016 throws
Prerequisite installation failed: RewriteModule error.
Resolution : open registry file start-> Run -> Regedit -> search for InetStpComputer\HKLM\Software\Microsoft\InetStp
change the Reg_DWORD "Major version" value from 10 to 7 , This is a bug of Skype for business where rewrite_2.0_rtw_x64.msi installation is looking for IIS7 , As Windows 2016 server has IIS 10 , This throws an error.
Once the Skype installation gets done change the Reg_DWORD vaue back to 10
