The dynamic link library (DLL) is a series of links used to make your computer run faster. Processes on your computer access the library and create links as necessary for programs to use. The c1.common.ni.dll error is a byproduct of the dynamic link library clutter.
The DLL is sort of like a cluttered toy room. If your kids throw all their toys in a toy room, then you know the toy is in there, but it might get lost, damaged, or downright broken. What you need is a maid to go in there and clean up the room on a regular basis to keep the toys from getting broken. The maid would also keep it organized, so the kids could find the toys easily.
Well, that is exactly what ZookaWare PC Cleaner does for your computer. ZookaWare PC Cleaner goes in and organizes and fixes all your DLL files in your registry. It makes it where your computer can quickly and easily find the files it needs and makes your computer run like new again.
