The most common cause is that your PC doesn't have the right software application installed to read and parse .MOBI files. A file extension (the text after the dot in the file name e.g., MOBI) is an abbreviation of a program name or function name that describes the format of the file. With file extensions, which appear as a suffix to the name of a computer file, your computer can differentiate one file format, like .MOBI, from other file formats, like .TXT (for text files) or .XLS (for Excel spreadsheets).
Because each file extension stores information differently from another, your computer requires a specific software program, called a host application, that is capable of opening, interpreting and rendering data stored in .MOBI files. If this host application wasn't installed properly on your PC, the computer then generates an error while trying to open .MOBI files.
Another common cause of failing to open .MOBI files is corrupt Windows Registry. Windows Registry is an internal database that stores information about the operating system itself and all software applications that have been installed on your PC. A large amount of data is constantly being read from and written to the Windows Registry when your PC is running. Without proper maintenance, Windows Registry gradually becomes bloated and contains empty or erroneous entries.
More specifically, two types of errors can occur in the Registry. The first type is caused by a mismatched file association that links .MOBI files to a completely irrelevant host application. The second type of error is related to empty file paths that point Windows to installation folder locations that don't exist.
