Visual Foxpro 9.0 Sp2 Portable Link

Because portable executables alter process loading paths and use unconventional registration techniques, Microsoft Defender and other AVs often flag vfp9.exe or launcher scripts as "Potentially Unwanted Program (PUP)". You must create folder exclusions.

Imagine Maria, a database contractor. She visits a client who has an old inventory system written in VFP 9.0 running on a Windows 7 PC in the back office. The PC is dying. The client wants a report extracted, but they have no install media for VFP.

Maria pulls out her encrypted USB drive, plugs it into a Windows 10 laptop the client provides, and navigates to E:\VFPPortable\vfp9.exe. She sets the default directory to the network share containing the client’s .DBF files, runs a report script she wrote last night, and exports the data to Excel. She then unplugs the drive. No registry entries, no leftover temp files, no “uninstall” needed. Visual FoxPro 9.0 SP2 Portable

Your most viable option is installing VFP 9.0 SP2 on a Windows VM (VirtualBox or VMware) and copying the VM to different machines. This provides portability without breaking the runtime expectations.

Save as Launch_VFP.bat:

@echo off
SET VFP_ROOT=%~dp0
SET PATH=%VFP_ROOT%;%VFP_ROOT%FFC;%PATH%
SET FOXPROSTARTUP=%VFP_ROOT%CONFIG.FPW
CD /D %VFP_ROOT%
START /B vfp9.exe

Take your USB drive to a Windows machine without VFP installed. Run Launch_VFP.bat. If successful, the VFP command window will open, and typing HOME() will return your USB drive letter. Take your USB drive to a Windows machine

After installation, copy the entire C:\VFP_Portable_Source folder to your USB drive, e.g., D:\VFP9_Portable.
