Moving this discussion to the Adobe Presenter forum.
Hope you have installed the right presenter version with the powerpoint.
You need to install 32 bit presenter with 32 bit powerpoint.
If the powerpoint is 64 bit, you need to install 64 bit presenter.
If you have installed it correctly, then
1. goto File->options->addins
2. Under manage select disabled items. Enable the powerpoint addin if found there.
Let us know if this solves your problem.

Thank you. Although the OS is 64 bit, I've found that Microsoft Office is only 32 bit. I've downloaded the wrong version. Thank you for identifying the problem so quickly.
I've uninstalled the 64 bit version, removed download files to the recycle bin and am downloading the correct version now. I will let you know if I succeed this time.
Although I had to download the 32 bit version twice (first time failed due to loss of connection), it is now installed and appears to be working just fine.
Thank you again for your assistance!
