If you get an error listing the c1d2hdao.dll file, this means a help file on your machine is having a problem. The c1d2hdao dynamic link library is a part of ComponentOne’s Doc-To-Help software, a tool that creates help files for developers by converting them from a document format to a standard Windows help format. Reinstalling to fix this problem isn’t a good option because you cannot be sure what software the file is attached to, so you are better off fixing the problem by cleaning the registry.
The Windows registry is a database that has information on the location of all the parts of every program installed on the computer. When you uninstall or move programs, the registry is sometimes not properly updated. Cleaning the registry removes unused entries and fixes errors.
