We think Visual C++ 6.0 was the best dev env ever made, but it had some weaknesses, so we kept improving it. VC6 Ultimate is a non-official collection of 500+ fixes, tweaks and new features for Visual C++ 6.0. These improvements make VC6 Ultimate an outstanding C++ IDE. Let's celebrate VC6's 20th anniversary by sharing it to the world.

• Fully portable and Win7/10 compatible
• Multicore version of VC7.1 compiler (It's fast)
• Real-time highlighting and diagnostics
• Real multicursor editing
• Improved UX and UI, including DarkSkin Theme
• Free (as in free beer)
• Every feature/change has a toggle
• Perfectly integrates with Whole Tomato's Visual Assist X.
• More at VC6 Ultimate's homepage and below.

1. Execute "create_shortcuts.js". It will create two shortcuts to launch VC6 Ultimate, one with the VC7.1 compiler and one with the VC6 Compiler.
2. If you want to enable Visual Assist X, open a cmd with administrator rights. Go in "VisualUltimate/AddIns/Visual Assist X" and execute "regsvr32 VAssist.dll". Visual Assist X is shipped with VC6 Ultimate but obviously without a purchased license. Please note that VC6 Ultimate is only compatible with this exact version of Visual Assist X.
3. It's an internal spare time project so don't expect everything to work in every setup, but feel free to reach out by email, discord, or to report any issue you may encounter.

For convenience, VC6 Ultimate includes a pre-installed Visual C++ 6.0 Enterprise Edition. You could also apply VC6 Ultimate as a patch on your original VC6 distribution.

If you are seeking for the original VC6 files (you lost the original installation CDs), the following external links can help:

• Original CDS here or here
• Instructions to install on modern windows
• MSDN Library for VC6
• VC6 Service Pack

Each feature can be enabled or disabled. Only take what you like, but be aware we can not check every combination.
