Microsoft Exchange Setup failing

Hi there,

I am attemping to install Exchange 2013 on Server 2012 R2 but I keep getting the below message.

Error:
The following error was generated when "$error.Clear(); 
install-ExchangeSchema -LdapFileName ($roleInstallPath + "Setup\Data\"+$RoleSchemaPrefix + "schema0.ldf")

" was run: "There was an error while running 'ldifde.exe' to import the schema file 'C:\Windows\Temp\ExchangeSetup\Setup\Data\PostWindows2003_schema0.ldf'. The error code is: 8224. More details can be found in the error file: 'C:\Users\administrator.E-NET\AppData\Local\Temp\1\ldif.err'".

Any ideas?
