Slipstreaming VFP
The
February 2007 CTP of VFP9 SP2 can be slipstreamed into the original VFP installation: this means that it's integrated into the setup process so it will directly install VFP9 SP2 - or, alternatively, VFP9 SP2 can simply be run from the slipstream directory (or from a USB device or CD) without the need to install the upgrade.
This alleviates the need to run the Community Technology Preview of SP2 on a virtual (or spare) machine in order to still be able to support applications which require VFP9 SP1.
To slipstream you need to copy your VFP9 CD to a writeable drive, and make sure the directory is writeable by unchecking Read-Only in it's attributes and selecting the option to cascade this change to subfolders. Then use
WinZip or a similar program to extract the patch file from the SP2 download - in this instance VFP9.0sp2-KB925841-X86-Enu.msp
The patch can then be applied using this command (adjusting for file locations as required):
msiexec /a c:\vfoxpro9.0\vs_setup.msi /p c:\temp\VFP9.0sp2-KB925841-X86-Enu.msp
