Installation Questions

I am installing dcoracle101pro.exe on a server that functions as a development environment as well as a production web server. When I attempted the installation it said that it was going to remove any old versions and I told it to go ahead and then another error message came up informing me:
"The installer detected an incompatible version of another Devart product. If you install several incompatible products, they may fail to function properly. It is recommended that you stop the installation, uninstall old data providers, delete all their assemblies and install the latest versions of all products."

So I stopped the installer and looked in Apps and Features and I dont see anything Devart related in there. I also dont want anything to break as I am going through this process. What is the best option for me at this point.
