If you just want something that you can use onsite without actually installing VFP, just take the following files from your VFP\Windows folders, zip them, then just unzip them in a folder on whatever machine and run the EXE. This is better than vrunfox because it's the full enchilada.
vfp9.exe vfp9r.dll vfp9t.dll vfpenu.dll vfprenu.dll gdiplus.dll (c:\windows\syswow64) msvcp71.dll (c:\windows\syswow64) msvcr71.dll (c:\windows\syswow64)
