cs_inter.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like cs_inter.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like ActivateProduct.exe - to follow. These files were created so that multiple programs (eg. ChemDraw Ultra) could share the same cs_inter.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when cs_inter.dll is attempted to be loaded either when ChemDraw Ultra is starting up, or in some cases already running. Some of the most common cs_inter.dll errors include:
- Access Violation at address - cs_inter.dll.
- cs_inter.dll could not be found.
- Cannot find C:\ProgramData\CambridgeSoft\ChemOffice2010\ChemDraw\ChemProp\cs_inter.dll.
- Cannot register cs_inter.dll.
- Cannot start ChemDraw Ultra. A required component is missing: cs_inter.dll. Please install ChemDraw Ultra again.
- Failed to load cs_inter.dll.
- The application has failed to start because cs_inter.dll was not found.
- The file cs_inter.dll is missing or corrupt.
- This application failed to start because cs_inter.dll was not found. Re-installing the application may fix this problem.
Your cs_inter.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with ChemDraw Ultra), or deleted by a malware infection. Furthermore, cs_inter.dll file corruption could be caused from a power outage when loading ChemDraw Ultra, system crash while loading cs_inter.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
