We use Windows Defender for anti-virus. Inventor has been running fine. Today we received a PDF files that stated it needed Adobe Acrobat Reader to open with all its features. So to see the PDF we installed that but the PDF still didn't function correctly. Unknowingly that install also installed McAfee antivirus. Uninstalled Acrobat and McAfee. Started working in Inventor again and then started getting this message when saving a part (ipt).
Closed Inventor and restarted, same thing. Copied the part to another name, opened the assembly in a new Inventor session and same thing. Used Task Manager and killed all McAfee processes. Removed all McAfee files and folders and deleted registry entries referring to McAfee. Restarted my computer and everything is fine now. So I figure McAfee tweaked my system to where Inventor files were being scanned but was odd that even after killing and deleting McAfee it still gave me that error.
Just putting that out there in case someone else runs into this.
