When I open a file in Inventor 2013 I get the error message "cannot open XML file" for 20 or more files.(See attachment) This has only been an issue since 2013 was installed. What do I need to do to correct this? Thanks
check project file and Application Options > Files tab. App Options controls this unless it is defined otherwise in the project file. The default location is at the Design Data folder level-- my installation, at least, doesn't have a folder named "XLS13" under it.
