DLLs are library files that allow multiple software programs to share the same functionality. Because they are shared files, they exist outside the program itself. Although this provides many benefits for the software developers, it provides also an opportunity for problems to appear. Improperly shutting down your PC or getting a virus infection could corrupt the icdllw32.dll, which could lead to DLL errors.
To fix these errors you need to follow these steps: Click the Start button. Type "cmd" in the search box. While holding CTRL-Shift on your keyboard and hit Enter. Click Yes on the prompted permission dialog box that appears.
Type: regsvr32 /u icdllw32.dll. Hit Enter and it will un-register you file. Now type the following command: regsvr32 /i icdllw32.dll. Hit Enter and it will re-register your file. Close the Command Prompt window and restart the program. Additionally you should conduct a full malware scan of your PC with a specialized program to make sure it is not infected.
