Ran the installer on my Win 7 Enterprise x64 laptop. When it finished I opened a command prompt and tried to run vfw, but the command shell didn't recognize it. I then checked path and found that it had been completely overwritten during the installation. There was now only one entry in PATH and it was pointing to the node sub-folder under vfw program directory. Everything else was gone.
Fortunately, I had a recent Windows system restore point to fall back to.
