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.

1. InstallSource (Z:\Applications\Server\Exchange\2013\64-Bit\RTM\en\)
2. ModifyPath (MsiExec.exe /X{DEDFFB64-42EC-4E26-0409-430E86DF378C})
3. 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.

Thanks for reply. I will check and let back.

I could not find where it installed the Language pack. It was installed by default during installation. Now i have some issue and want to remove it but on step 8 "Language" it generates an error message. When again try to uninstall, it simple give me an error that the setup is incomplete, rerun the setup to complete the installation.
