Powerpoint 2007

Hello Sam

Thank you for your question.

You should be able to use existing templates in the 2007 version of PowerPoint.

Try the following:
On the Design tab, click the dropdown arrow next to Themes.

Select Browse for Themes.

Change the File of Types to Office Themes and PowerPoint Templates (if the template is saved as a .pot file), or All PowerPoint Files.

Choose Apply.

Alternatively, try using the Home tab, clicking the dropdown arrow next to New Slide and selecting Reuse Slides.

Use the Browse button in the panel that opens on the right of your screen, to select the file containing the template you wish to use.

Once you have done this, then you can make any adjustments you want to and save the PowerPoint presentation as a Theme.

Then import the Theme from the Design tab, as outlined above.

I hope this helps.
