I’d like to uninstall Prezi Video, but when I try to open the uninstaller, I get this message – “Uninstall Prezi Video” can’t be opened because Apple cannot check it for malicious software.
Hi @Monte_Lewis, could you send me a screenshot of that message you get?
Hi @Monte_Lewis, could you tell me your Mac OS version?
Mac OS Catalina version 10.15.4
Hi @Monte_Lewis, you can release this blocking in the system preferences under security and privacy:
If you don’t mind, could you tell me why are you planning to uninstall the application?
Hope my recommendation helps!
I don’t seem to have that Open Anyway option?
I wanted to add Prezi Video and use with Zoom calls, but my Prezis are on Prezi Classic. I don’t think Prezi Video works with Prezi Classic? And because I can’t uninstall, my Zoom, Webex, GoToMeeting, Teams cameras are also defaulted to Zoom Video.
I tried again and it worked this time. Still interested in Prezi Video. Is there a way a path for my Prezis on Classic to migrate to the new Prezi?
Hi @Monte_Lewis, the Prezi Classic migration is not out yet, but it will be available in the future.
Thanks for your help. I would be interested in migrating when that becomes available.
I would like to uninstall Prezi Video…it is interfering with other apps I use.
Please post where the uninstaller is.
When you download the Prezi Video, you have the option to open Uninstaller.
Hello @Milton_Santiago, you can follow the previous recommendation to uninstall Prezi Video completely, but you’re also able to change the camera settings in Google Chrome by selecting the integrated one, so the PV camera doesn’t interfere with other applications
I am having trouble with Prezi Video “stealing my camera as default.” I have only tried PreziVideo once. Ever since, on several applications for which my camera activates, I get an error message that PreziVideo is not active. I have to switch cameras every time. I looked on Prezi app to switch the default, but found no setting. I changed the default on my other application (for instance doxy.me for telemedicine) but Prezi “steals back” the camera every time and I get an error message. I then uninstalled Prezi and it still happens. Then I looked in Mac settings to disable, and Prezi (now uninstalled) doesnt even show up so I cannot disable it - perhaps I should have tried that before uninstalling)
Using a Macbook Air with the latest operating system
Its not that camera is not switchable, but it is getting old very fast as I make many telemedicine calls and have to switch the camera EVERY time I initiate a new call
I’m sorry to hear the inconveniences this issue have caused you.
I will report this to our developers so they can look into a solution.
Until then, I would suggest you to manually remove the Prezi Video Virtual Camera plugin from your Mac. You should be able to do this the following way:
- Open up Finder on you Mac
- Click on GO on the top taskbar, select Go to Folder
- Paste /Library/CoreMediaIO/ and open the folder.
- Look for a file called PreziVideo.plugin and move it to the trash.
- Restart the application that is having issues with the camera and see if the camera has been removed. A computer restart could be helpful here as well.
If you decide to reinstall Prezi Video this plugin should also reinstall so this should not interfere with future usage of our product.
Let me know if this helped!
Yes it worked!!! Thanks so much.
It was actually hiding in a folder under plug-ins called DAL.
You should monitor other help feeds. Looks like since my post, which I can no longer find, a number of users had the same issue of camera being stolen and none of the posted suggestions match your great one
