Solved Answer

DLL (Dynamic Link Library) files are essential components in the Windows operating system. They contain code and data that multiple programs can use simultaneously, helping to save memory and reduce disk space. These files allow various software applications to perform common functions without requiring their own separate code for these tasks.

One such error is the “dciman32.dll not found” or “dciman32.dll is missing” error, which typically occurs when you attempt to launch certain applications.
