Insert Package Object macro & Nitro PDF software

Hi!

A macro is running throughout quite a large workbook that, where triggered, prompts the user to insert an object and resize to a specific size.
We are having intermittent issues where the inserted PFD object will pop up as a white box and corrupt the excel workbook to the point where it cannot be saved without the objects being deleted.
The PDF software running on the computers is Nitro PDF. Is there any rectification to this by fixing the macro below, or am I best to contact the Nitro PDF support team to see if its an issue on there end as thats the default PDF platform:

Sorry Sudbhavani, Im not sure of a work around? The error specifically states:
Error inserting object: Cannot insert object

There could be an issue with Nitro PDF's integration with Excel, as it may not properly register as an OLE object handler.
Fix: Try testing the macro with a different PDF viewer, such as Adobe Acrobat Reader, to see if the problem persists. If it works with Adobe, it suggests a compatibility issue with Nitro PDF.

Thanks Subdhavani

I have trialled it on a different computer with a different pdf software; still the same issue. I have also tried a different class type (docx) to no avail. Lastly, I copied the macro to a blank workbook and the issue has persisted; so I dont believe its a clashing macro issue
