While working on Excel worksheets, we use many functions and some control libraries. The most commonly used control library is calendar control which is used for the functions related to calendars.

When we have created an Excel spreadsheet using these control libraries and send these files to someone who has not installed the control libraries we are using, they can have trouble using these spreadsheets because they will throw an error saying the mscomct2.ocx file is missing.

The MSCOMCT2.OCX file is related to the window additional control libraries for control in Visual Basic For Application (VBA) which is stored in the folder of window drives on any device like a computer or laptop.

The picture of the error is shown below.

If the file is not installed on our device at the location and may be missing, we may get an error in the application function, which will not work properly.

While we are performing some functions with the date picker and finding the missing file in the libraries, in that case, we have to install that file on our computer.
