Opening PPTX files

Hi everyone !
I'm trying to open the pptx files uploaded by my professor.
I have purchased and installed Microsoft Office for Mac 2011.
However, every time I go to open the pptx file it downloads as a zip file.
After unzipping it results in a bunch of xml and html files, none of which even relate to the original powerpoint.
My classmates who only have Open Office don't even have this problem, and the powerpoint simply opens when clicking on the link.
Please help !
Thanks

Either post in Microsoft Office for Mac forums, contact their tech support or download Open Office for Macs.
None of the above software are Apple products.

SharePoint 2010 and PowerPoint 2010: Open PPTX File in Edit Mode and Open PPSX in in Slide Show Mode

I have the following issue while opening PowerPoint PPTX file and PPSX from the Document ID link provided by SharePoint 2010.
Issue
Initially when I opened PPTX file from the DOC ID link from SharePoint 2010, it is opening up in Slide Show mode which is not how we want it to be.
For PPSX, it is opening in Slide Show mode which is what we wanted.
Thus, I did some research online and found this article at support.microsoft.com/kb/q299824 which requires some modification to the Registry of the client machine.
I did the change as follows
Open Registry
Look for “Computer\HKEY_CLASSES_ROOT\PowerPoint.Show.12”
Set BrowserFlags value to a
After the change, PPTX is opening in Edit Mode in PowerPoint which is correct but PPSX is also opening in Edit Mode in PowerPoint which is not correct
This issue only occurs if I open the document from the Doc ID link in SharePoint. If the documents are downloaded, it will not have this issue.
Questions
Can I set PPTX to open in Edit Mode and PPSX to open in Browser Mode?
Is this fixed as in if I change the registry setting it will affect both file types?
Is there other ways I can achieve opening PPTX in Edit and PPSX in Browser Mode?
[Environment]
My Client machine is running on I.E 9 and Office 2010.
Thank you.

Hi,
To make the PPTX file open in Edit mode and PPSX file open in Slide Show mode, I recommend to edit the registry key HKEY_CLASSES_ROOT\PowerPoint.Show.12 to 8.
I tested the scenario in my environment with changing the key value to 8, after that PPTX file opened in Edit mode and PPSX file opened in Slide Show mode.
Best regards.
Thanks

I am trying to open pptx files on my MacBook Pro and continue to get "No Text Converter is installed for this application" even though I have dowloaded several converters that were supposed to work and I just downloaded Apache Open Office 3.4.1

I am trying to open pptx files on my MacBook Pro and continue to get "No Text Converter is installed for this application" even though I have dowloaded several converters that were supposed to work and I just downloaded Apache Open Office 3.4.1 with no luck. I am able to open docx files with the converters I have installed but not pptx files.

The PPTX file type is primarily associated with 'Power Point' by Microsoft Corporation.
This is the new format for Microsoft Office documents.
It is a combination of XML architecture and ZIP compression for size reduction.
To open Office 2008 for Mac documents (format .xlsx, .docx, .pptx) in Office for Mac 2004, you must download and install the Open XML File Format Converter. This article describes how to obtain and install the Open XML File Format Converter for Mac.

Instead of all that, and buying OfficeMac etc...
Try to see if the FREE LibreOffice suite will open the file on your Mac.

Keynote freezing when opening pptx files

hi there,
so i have keynote on my mac with iwork 08 since i got it two summers ago and i have never had this problem before. i think i have even opened pptx files before and they have worked, so im not sure why its not working now.
but the problem is when i try and open pptx files for school it will start the opening screen but stays on it forever and i have to end up force quiting the program. the bar that says loading only gets like 10% of the way, but never further!
whats the deal? i downloaded the latest update for keynote, but it didnt help.
i got the file via email though and can quick preview it both in finder and in mail. also the HD heats up when i try and open it and it sounds like it is strugglin'!
thanks
last second thought- i think it has happened just since my update to snow leopard.. maybe thats the problem...

There are two libraries on your Mac:
1. In the System folder
2. In your User folder
It's the second one that has Preferences.
I'd be very surprised not to see a plist in the User>Library> Prefs folder, as each time you launch an app, a plist is created.
However, if this is the case, my suggestion is to delete iWork and reinstall it.

My iphone 4 will not open pptx file.

It will open the same file if I convert it to ppt first. The file size of the pptx file is less than 700k. After converting to ppt it is a little over 1 meg and it will open fine. How do I fix this? Manually converting each time is not an option.

What are the attachements? The iPhone may not be capable of opening them.

I can't open pptx files on keynote 6.2

Hi. I am an Iwork user who got a pptx file from a windows user. The problem is that I can't open it on keynote, even when I can open it on my ios devices. I can see it in preview, but can't save it. It is strange because I had been aple to open other powerpoint's docs. before. I had tried changing the doc title, the doc .name, and if might be useful, might even try to convert it to something else. But, my question is, isn't keynote supposed to open it? Thanks.
jro

Gary: thanks for your reply. Neither one or the other. As my title states, I am using the latest version of keynote, and also, as I said, I am able to open it on my ios devices (ipad and iphone) so, that means that the file isn't corrupt.

Unable to open .PPTX files?

Hello,
I'm hoping someone might be able to help me. I am unable to open my college's lecture notes which are in the form of a Power Point presentation. I am running MS Office 2011 which is fully updated. I have attached some screen shots with the hope that someone might be able to help me out. The file will not open, and when I click repair it tells me that the file is either corrupted or was made with an older version of Power Point. Any help would be appreciated!!

OPENING .PPTX File"This document not in powerpoint format"

Hi, I am new and am hoping somebody can help me. I received a file a couple of hours ago from a friend who uses Microsoft Power Point, I have a presentation in the morning.
I have downloaded the file, it is .pptx. When I click on it to open it it in Keynote I get an error message that tells me "The document is not in Powerpoint Format." No matter what I try to get this to open it will not. I have a Mac Book Air running v:10.8.3 with the latest version of Keynote.
Would anyone be able to offer me help or suggestions? Here is a DropBox link to the PPT. https://www.dropbox.com/s/fcj1ivb9qucr5j0/Sunless%20101%20Course%20-%202013%20-% 20Hedlux%20-%20v16.pptx I have opened hundreds of .pptx files in Keynote and this is the first issue I have ever had.
Thank you in advance for any help that anyone can give me.

Your PowerPoint file runs OK on my machine. I can think of a number of issues that are causing the file not to open.
However, what I would do, as you have little time to problem solve this issue, is playback the presentation in Open Office. This application is freeware its used by many government departments and universities in every country of the world. I use it daily in place of Microsoft Office.
Download it here:
Open Office for Mac
Change the security setting for this download only as the Mac OS settings prevent all downloads except those from the App Store, once downloaded, you can change it back:

Can´t open pptx file in recieved email

I have an iphone 5 with sw 6.1.4.
When i recieve an email with a Powerpoint .pptx attachement I can´t open it after the attachements has been fully downloaded.
Where the file should be is just a text (See attatched file: ---.pptx).

From what information I can find, it appears that that format is not supported by the device itself.
*Edit: On page 150 of the manual (http://manuals.info.apple.com/en_US/iphone_user_guide.pdf) I located some more information about what is supported.

Can't open pptx on my iPad

Recently I've found that I can't open pptx files from my email on my iPad. This is really frustrating and whilst previously the formatting was never great, it used to work and I could review presentations whilst on the move.
Apple please get onto this and provide a fix.

Look at the Rccharles answer on this post.

Also, you can download these free MS Office apps (Word, Excel, PowerPoint) to view (but not create or edit) these files.

Nice surprise reading pptx files!

I needed to send a powerpoint file (from a Windows laptop I have to use for work) to my iPad to take on trip (but not to edit).
Without buying extra apps (Keynote, D2G etc) the easiest way is to convert the save the powerpoint file as a pdf.
I emailed the file to myself and picked it up on the iPad. In fact I'd accidentally attached the .pptx not the .pdf version. Out of curiosity I opened the .pptx attachment in the email, and was amazed that most of the slides appeared exactly as original! Text slides with simple shapes were fine, but more complex charts and tables did have formatting problems.
This may be of interest to anyone wanting to view simple powerpoint files. I don't know if this only works with .pptx or if .ppt would have same results.
Subsequently I sent myself the .pdf file I meant to send, and this appears perfectly on the iPad and can be kept on the pdf "shelf" of iBooks (when you tap on the opened file, an "open with iBooks" button will pop up)

Unfortunately it does not appear to work consistantly... I have had multiple issues trying to preview and or open pptx files on my iPad and or in Keynote...
Very interested to hear any ideas that people may have with a viable viewer... The challenge is that I can't control what people send me and would like to be able to open them on my iPad.

Mail App: I OPen a pptx file, I can't close it to return to see other Mail. Please tell me how to procedure? Thanks a lot!

Problema in Mail App. I OPen a pptx file and I don't know how to close it in order to access the other mails. I'm a new user. Thanks a lot!

Tap on the screen - right on the open file - and you should see a blue Done button in the upper left corner. Tap Done to close the attachment.

I get "We can't verify who created this file" for every PPT or PPTX file I open on my local network (Win 7 only, not Win 8)

I've searched around, and perhaps I've missed it, but I have a specific problem that just started today (4/1/2014). I have 3 PCs in a local home network and they all have been sharing things fine so far. PC1 is my main storage computer (Windows
7), another is a laptop (Windows 7) and a third is a laptop (Windows 8.1).
On the Windows 7 laptop, when I open Windows Explorer and navigate my way to a file I want to open (which is stored on PC1) and double click on the file to open it USED to just open using the right program (PowerPoint2007) which I have fully installed on
the Win 7 laptop. Note also that "Microsoft Office (2010)" came pseudo-loaded on the laptop, but I have set the default for all PPT and PPTX files to be opened using PowerPoint2007. I've had a few hiccups in the past where this undesired,
not-fully-loaded version tries to get in the way of me opening files with PowerPoint2007, but right now all files are set to open using PowerPoint2007.
So I'm not going on the internet, I'm not using IE, and this is only happening with PPT and PPTX files and only on my Win 7 laptop. DOC/DOCX and XLS/XLSX files open fine with the 2007 version of the Word and Excel respectively. All files, including
the PPT and PPTX files on PC1 are openable without trouble on the Win8 laptop with PowerPoint2007.
Any idea why this would suddenly start happening?

Sorry, I should have said that I'm having this issue on Win7 Enterprise SP1 and not XP.
I'm having trouble understanding how cacheing is related to how windows resolves this security violation, and why changing the Internet's custom security settings makes the caching problem go away? You are correct in that running a mdb file from
the desktop does not produce the warning; however this is a database housed on a shared drive so that the database is accessable to other users...
unfortunately unblock is not presented as an option in the file properties, and even if it was that seems a bit impractical to do for every single zip file on a share drive which would accumulate more files as multiple users add to it.
Also: I have two computers with the same settings in both the trusted sites and the Launch apps, but one opens fine and the other does not.

Keynote won't open some Office Open XML / .pptx files

I'm a developer trying to generate .pptx documents (i.e. Office 2007, Office Open XML) and would like to open them in Keynote. I already can successfully generate .pptx files which PowerPoint opens fine, but those same documents don't open in Keynote. I get the following errors in Console.app:
3/3/08 6:39:24 AM Keynote[68427] Couldn't generate XML from /Users/tlrobinson/Downloads/1204554878463.pptx
3/3/08 6:39:24 AM Keynote[68427] errors (1):
3/3/08 6:39:24 AM Keynote[68427] (0) The document is not in PowerPoint format.
Has anyone been able to generate .pptxs that Keynote will open?

Welcome to the discussions, tlrobinson.
To my knowledge, Apple only supports opening of .ppt documents, hence the error message you're getting.

Unable to open some Powerpoint 2010 PPTX files which were emailed to me

A presentation created by a colleague was emailed to me via Outlook 2010. After saving the file (save attachments) in a folder, I cannot open the PPTx file. I get the following error ina dialogue box:
     Powerpoint found a problem with content in XXX.ppt.
     Powerpoint can attempt to repair the presentation.
     If you trust the source this presentation, click Repair.
When I click on 'Repair', I get another dialogue box which says:
   This error can be caused by following conditions:
    ---- none of which are applicable to my system. Can somebody help me with this problem?

Hi there. I had a similar issue. How I was able to resolve this was by doing the following. You will need Office 2003 (with compatibility pack) and Office 2010.
1. Open the Powerpoint presentation in Powerpoint 2003.
2. Once you have the presentation opened in Powerpoint 2003, save it as a Powerpoint 2007 presentation.
3. Open the presentation using Powerpoint 2010. You may get some error prompts (you can ignore). Click on save as, and save it as a Powerpoint 2010 presentation. Close it.
4. Now open it again using Powerpoint 2010, you should be able to work on it without any issues.
Not the most elegant solution but it worked for me. I hope this helps.
