Common installation instructions for downloadable add-ins.

These utilities and files have undergone reasonable testing and I use most of them for my own work.  However, I do not guarantee they will function under all circumstances.  While I have programmed the software with professionalism, the truth is that someone somewhere sometime will go beyond what I consider feasible.  If that is you, and the software breaks, you are on your own.

I check the files for viruses before I upload them to the Web site.  According to the virus protection software I use, they are virus-free.   Each product is in a single executable (.EXE file) or in a single zip archive (.ZIP file).  Click here if you need a program to unzip the files.
