Welcome to Adobe Forums.
Which version of Adobe Presenter are you using ?
Which version of MS Powerpoint are you using ?
Do you have Windows Xp or Windows 7 ?
Does it happen on a blank presentation as well or with a specifc presentation ?
Make sure you have Presenter 8.0.2 update installed.
Here are the answers you asked for:
Which version of AP are you using? = 8.0.1 Build 260
Which version of PPT are you using? = PPT 2010
Do you have Windows XP or Windows 7? = Windows 7
Does it happen on blank presentations as well or with a specific presentation? = It happens with both. I have even tried various save as tactics to try and trigger it into running. Once it fails, the only thing that I have gotten to work is the process I described above.
Make sure you have Presenter 8.0.2 update installed = I would install the update, however the ribbon/help does not display the update option, and the other adobe installers I have seem to overlook Presenter.
Can you share where I can find it, also what does it fix/do?
I had this happen again to me (ribbon failure of presenter commands)
I swapped user on my machine and logged in as a different user...and functionality was restored.
Why would the switch make a difference?
Also, to Jorma's point...I have tried installing the patch referenced above here...and I too am still showign 8.0.1 Build 260.
This issue continues to pop up for me...is there a work-flow that you can suggest to eliminate the need to change user accounts?
How do I get this tool to work reliably for me?
The ribbon works sometimes (5% of the time) and not others...so Presenter recognizes me periodically under this user account...what else can I try?
