Issue Description

FIX: This hotfix addresses a performance problem when stepping through Source Code downloaded via a Microsoft Reference Source Server. Additionally, this hotfix prevents an unnecessary EULA dialog that can occur repeatedly on debugger startup.

This patch is installable on 32-bit and 64-bit systems. If installed on a 64-bit Vista or later system, a manual step is required to be performed after installing the patch. Create an empty file using notepad called “symsrv.yes” that resides next to symsrv.dll. By default this file is installed in the following locations:

InstallDrive\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\Remote Debugger\x64

InstallDrive\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\Remote Debugger\ia64

If 32 or 64-bit remote debugging components were copied to a remote machines prior to installing the patch, the symsrv.yes file needs to be placed alongside those installations as well.

All 9 languages now released.
