There are several reasons why you can't find a project or library in Excel. These include:

  • Missing Reference in VBA: This error in Excel may be due to a missing reference in the Visual Basic for Applications (VBA) editor. This can happen if the code relies on an external library or object incorrectly referenced.
  • Corrupted Excel installation: A corrupted installation of Microsoft Excel can also result in the "can't find project or library" error. If essential files or components are damaged, it may affect the proper functioning of the VBA editor and prevent it from locating the necessary projects or libraries.
