This issue can most often be attributed to a missing application library. Now normally when you have a missing file, the first thing you are going to do is to find and double click on the file in question, but unfortunately for your windows operating system this is not an option. The file is not located in the program files section and consequently you will not be able to locate it using the usual search procedures. Now one thing you could do is to resort back to the days of typing the file name and looking for it in the directories. However, with the introduction of the Microsoft platform, it was necessary to employ the use of the Microsoft tools to open up windows files and this in turn lead to the creation of Microsoft's built in, and still amongst the most used, file library, known as the "COMDLL" which stands for "Computer Library Object".
The file you are looking for may be hidden deep within the "Program Files" section of your windows operating system. One of the main reasons why you are experiencing this problem is due to the fact that you are not always running the latest version of the operating system. Another reason why the file is not found is because you have either not fully updated your pc or your windows installation is configured such that it is blocking access to some of the required DLL's. Now normally with a fresh installation of windows, you will find that the DLL's should be able to load successfully. However if you are having problems, whether its system wide or specifically relating to the DLL's that are causing error messages on you pc, then it is advisable that you use the "registry cleaner" application to clean up your registry for you.
