I have a vm client that I have installed 2008 R2 X64 SP1 Server on. Hard drive space is 31 GB with 4 GB of memory.
SelectServer x64 ver (09.00.00.113) When installing this version it first installs the .net framework 4, Micrsoft XML Parser (MSXML) 6 (64 bit), Microsoft SQL 2008 R2 Express SP1. At that point I get a message that there was a problem installing SQL Server 2008 R2 Express.
