I'm trying to install SQL Compact 3.5 SP2 after I've installed SQL 2012 RC0, on a x64 Windows 7.
The x86 installer goes through fine.
The x64 installer fails, with the error:
"Error 25543.Failed to save changes to XML file c:\Windows\Microsoft.NET\Framework64\v4.0.30319\\CONFIG\machine.config, system error: -2147024864"
Note the \CONFIG (double backslash) where there should be a single backslash.
How could I resolve this issue?
