Hi,
Based on this error, possible cause may the path of language package is too long. Please check the following things:
Where is your language package installed? Please check it.
Under 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{DEDFFB[0-9a-fA-F]{2}-42EC-4E26-[0-9a-fA-F]{4}-430E86DF378C}", please check the following entries. By default, it should be like this.
InstallSource (Z:\Applications\Server\Exchange\2013\64-Bit\RTM\en\)
ModifyPath (MsiExec.exe /X{DEDFFB64-42EC-4E26-0409-430E86DF378C})
UninstallString MsiExec.exe /X{DEDFFB64-42EC-4E26-0409-430E86DF378C}
Under 'HKLM:\SOFTWARE\Microsoft\ExchangeServer\v15\setup, check this entry MsiInstallPath. By default, the value should be “C:\Program Files\Microsoft\Exchange Server\V15\”
Best Regartds.
