Usually, such errors occurred for video game and any other software/application which needed heavy graphics/animations. on their own machines “directly.” These special DLL files are handled by your PC while playing PC games (usually high-end/high-graphics games), the file used to provide information to the CPU & GPU while playing that game. Typically such errors occurred when people tend to install “downloaded” games/applications etc. Then I completely checked all the systems files including system32 folder the DLL file is missing.
Recently I was installing the latest game, and after 9% it got stuck, and the error message is shown as an error, and it was 'ISDone.dll is missing' unable to read data. Your PC requires Dynamic Link Library ( DLL) files to (or “intending to”) making daily tasks, and they apply in a virtual database called ‘ The Registry’. Isdone.dll is an active link library file - it has a particular purpose that the system handles it in order to perform multiple tasks.
