Prezi.exe error with DirectX

Hi There. I’m having a problem with the Prezi.exe file. I have a few presentations on my profile in prezi.com. I used to work downloading the Prezi to my computer to work offline… I did this process for a year, and yesterday when I wanted to download the last version of my prezi I had a problem.
When I download the file and unzip it … I find only one file called “Prezi-Windows.exe” (Time before that folder contained a lot of files and folders and not only one execute file). The problem is that when I make double clic on this file appears a message saying “Directx is missing… Install it please and try again”. So, I decided to install “Directx” (from the zip file). Then I rebooted the machine and try again and I’m having the same problem, “DIrectx is missing…” I tried in 2 different machines… one with Windows 7 64 bits and the other Windows XP 32 bits.
please help me with this issue.

I have had the same problem mentioned above.

We have the same issue. But our users are downloading and loading them from a Citrix Windows Server2008 R2 machine. It used to work according our users. Probably something to do with the updated executable.

The error appears when we have a prezi downloaded and run the prezi-windows.exe. The error states: “DirectX is required to view this prezi. Please install it and run again.”

See Pastebin link for the DXDiag Information: http://pastebin.com/NukT0KfN

Please advise…

Hi Vanda,
I ran DXDiag.exe and here are the results…

Hi Vanda,

I downloaded the test file, opened it and still the same error message appears:
“DirectX is required to view this prezi. Please install it and try again.”

I tested the file on 4 (pretty identical) Citrix Win2008R2 machines, but on every machine i get this error.

Please advise…

Grtz,
Patrick

Hello everyone! I have the same issue. I have run the test file but still the same error message. Any progress on this?
Thanks!

Thanks in advance Vanda. I will wait for the answer. :slight_smile:

Hi Vanda, I ran the exe file and I received the same message…

I am having the same issue on Windows 7 x64 machine. It used to work. Thanks, Beth.

Any updates ?

Could you please at least give your users a workaround:
1) By rolling back the new updated executable
or
2) Add the previous version, which used to work, of our presentations to the Downloads, so that we at least can choose which of the presentations we want to download (the new updated executable or the old-fashioned-way).

This is getting too long now, very annoyed…

Did they fix it yet?

Yes, we need an answer as soon as possible :slight_smile:

do you have a fix fot this problem?

I’m still waiting for a fix. Do you have a fix? I can’t believe that this is not solved yet, I’ve been waiting two weeks…

As described in the other topic “Portable Prezi in windows does not load”. There is still no fix or even a workaround provided by Prezi.

I think we need to cancel our contract first and get a refund because you guys are not meeting the expectations of the terms we agreed to in the first place!

Hi Vanda, many thanks for your answer.

I installed a new copy of Windows 7 Ultimate, and then I tried to run a Prezi Portable but never worked. However, I upgraded my Graphical driver downloading from the official web page, and now after to read your email I tried again to see if my problem was fixed. Now the Prezi Portable is running correctly. So, I want to share with the other persons who have the same problem, that may be a solution makes an upgrade of the Graphical Driver of your computer. :slight_smile:

THanks anyway por the help.
Kind Regards.
