I linked (accidently) a Mathcad 14 graph into a Powerpoint presentation. I have deleted the presentation from Powerpoint, deleted the entire Powerpoint file, and still Mathcad thinks that the originating file is linked. I can only open the file in Mathcad as read only, so I cannot change anything or delete the file. How do I kill this file?? Thanks Peter

then, go to format -> slide design, choose to show all documents, and choose the corrupt powerpoint file. now, go to insert -> slides from file, and select the corrupt powerpoint file. make sure you are set to insert all slides, and then import. if that works, great! i suspect, however, that you might crash at that point. if so, try repeating the process, inserting specific slides one by one until you find the problem one. after that, save the file, making sure that fast saves are off (in preferences / save).

How you present the material in a speech can say as much to your audience about your expertise on a subject as the actual content of the speech itself. Microsoft PowerPoint is a powerful multimedia presentation tool capable of producing captivating and informative slideshow presentations. Microsoft PowerPoint is a program that is part of the Microsoft Office suite and has been emulated in open-source programs such as OpenOffice.

Open Microsoft PowerPoint. In Windows computers, PowerPoint can be accessed by clicking "Start," then "All Programs," then the "Microsoft Office" folder. Mac computers will install a link to PowerPoint on the taskbar. Click "Design" and choose one of the templates that open in the design tab. Additional designs can be downloaded from Microsoft.com. Click the area of the slide that says "Click to add title" and type your desired title. This slide is referred to as the title slide. Create a new slide by right-clicking on the title slide and choose the "New Slide" option. Windows users can use the keyboard shortcut by holding "Ctrl+M" with PowerPoint opened. Click the area of the slide that says "Click to Add Title" to add a title or "Click to Add Text" to add text to the slide. Type the information that you would like to display on your presentation in the text box. The text box gives you the option to add text, pictures and tables and even create graphs by clicking on one of the respective icons at the center of the text box. Click on a slide that you would like to add a special transition to and click the "Transitions" tab. Select a transition by clicking on it. Click on a text box that you would like to animate and click the "Animations" tab. Select an animation by clicking on it. Click "File" and "Save" to save the PowerPoint presentation. Open the saved presentation, pressing the "F5" button to open the presentation in full-screen mode.

Guys who need windows 7 key can go link:# https://windows7professionalblog.wordpress.com to got. My key got here and after i used is great works.

Open your powerpoint file, click "File" then "save as" and click the drop down box for "Save as type". Change this to "PowerPoint 97-2003 Presentation" and give your converted file a name and save it.

This should make it readable by all versions of PowerPoint currently in use.

Run it in the compatibility mode. Right-click on the executable, choose "properties", then the "Compatibility" tab. Check "Run this program in compatibility mode for". Choose the latest version of Windows the program ran on, check the screen setting that applies for your application and click "OK". Now you can start the application!

My guess is that the engineers at PTC haven't figured out how make their products compatible with Windows 7! I painfully found that MathCad 14, 13, 11 do not work on Windows 7 (I have Windows 7 Pro)! They install, but the application can't even start! However, MathCad 2000 does work on this outstanding platform; I was amazed! You could use that version in the meantime, hoping that PTC will solve this problem soon! Or install Mathcad 14 on the virtual PC that works in XP mode.

can anyone get me information whether Mathcad 14 is working on Windows 7

Thanks in advance

This is because it is in Powerpoint Presentation format. You will need Microsoft Powerpoint to edit it.

Alternatively, if don't have Microsoft Powerpoint (or don't want to spend the huge amount of money it costs) you can download Open Office and edit it for free. Here is the link to Open Office: http://download.openoffice.org/index.html
