Adobe Systems ( ADBE) expects its fourth-quarter results to come in at the high end of its earlier targets, thanks to solid demand for its Acrobat and Creative Suite products.

In its mid-quarter update, the San Jose, Calif., software maker said it expects results to be at the high end of its September forecast for earnings of 27 cents to 29 cents a share and revenue of $490 million to $510 million. Analysts polled by Thomson First Call predict Adobe will post earnings of 29 cents a share and revenue of $506 million for the quarter ending Dec. 2.

Adobe said Acrobat, its document-viewing software, and Creative Suite, a set of design and layout products, are driving its fourth-quarter results. In addition, the company noted solid demand in all of its major geographic regions.

Adobe also said it continues to expect that its acquisition of Macromedia ( MACR) will close in the fall, either in late November or December. Adobe agreed to buy Macromedia in April in a deal valued at the time at $3.4 billion.

On Monday, Macromedia reported 29% growth in its fiscal second-quarter net income, with earnings per share that topped analysts' mean estimate by 5 cents.

Adobe shares recently changed hands in after-hours trading at $32.15, up 16 cents.
