When using MS Excel with one or more PI add-ins enabled (PI Data Link, PI Tag Configuration, or PI Batch View for Excel), Microsoft Visual Basic for Applications errors are encountered. While opening Ms Excel these errors can be seen or while using functions within add-ins, like the Insert Trend function in PI Data Link.

VBA Errors:

  • Could not load an object because of unavailability on this machine
  • Compile error in hidden module: mod Add in
  • Compile error in hidden module: Main
  • Object library invalid or contains references to object definitions that could not be found
  • Run-time error ‘459’: Object or class does not support the set of events
  • System Error &H80040111 (-2147221231). ClassFactory cannot supply requested class


From a variety of issues these errors originate, but they are often related to a malfunctioning MS ActiveX control used by add-in, or by old cached VBA files. The following steps may help to resolve this issue.

Verify required prerequisites and settings

  1. Make sure that the add-ins and related items are installed properly. For example, if the PI SDK is not installed, then that will affect many of the PI add-ins.
  2. Check that the ActiveX controls are enabled (not disabled). In Excel select File> Options> Trust Center> Trust Center Settings> ActiveX Settings. This should NOT be set to ‘Disable all controls without notification’.

Check for cached *.exd files

Search for all files(including hidden file) with the extension *.exd. (By default, Windows does not search for hidden files, so you must change that setting in order to see them). One way to find all *.exd files in a given hard drive is by opening a command prompt, navigating to the root directory of the drive (for example, by first entering “C:” and then “CD \” to get to the root of the C: drive), and then running the following command: dir *.exd /b /a /s
If you find any exd files, reopen Excel by deleting them.

These exd files are created automatically when required, but cleaning is not done automatically and these types of errors may occur, particularly when the runtime files are updated through Microsoft patches.
