The European Commission said Thursday that software company Adobe Systems Inc. has not made any complaints so far about Microsoft Corp.’s plans to ship its new Office software without Adobe’s PDF file reader.

In an ongoing dispute with Adobe, Microsoft said earlier this month it had canceled plans to include an automatic way to save documents in the popular Portable Document Format in Office 2007, due out to consumers in January. Instead, users will have to download separate, free software to save documents created in Office products such as Word and Excel as PDFs.
