Cannot open files with the EXTENSION of the PPT FILE

I can't open a file with the following extension using PowerPoint ppt. The message below is what I get-

The selected file is not a valid Microsoft PowerPoint file. It may be a file created by another program.

Try by double-clicking the file in Windows Explorer to see if another program opens to it. If PowerPoint opens again when you double-click the file in Windows Explorer, it is possible that the file is not a PowerPoint file, but its extension has been renamed to be that of a PowerPoint file type registered (for example, .ppt, .pptx, .pps, .ppsx, .pptx, .pot or .potx) but the file is not a PowerPoint file.

To determine which program can open the file, try one of the following:

  • Contact the original author (if known) to know what program you used to create this file. Then rename the file with the correct extension so that it can be opened by this program.
  • Try opening the file in other programs.
  • If you or someone you know, are very knowledgeable about software, review the file header in a text editor to determine which program can read the file.

Another possibility is that the file has been damaged during transfer from another computer. Trying to transfer the file again.

The file may be damaged. If you have a copy of the file backup, use it. It is not possible repair corrupted file.

  • Error message"the file is maybe damaged or corrupted 1610153464 / also cannot open projects in the background 26: 142

    Hi all

    I hope someone can help me.

    I use AE CC/Windows 7 on a Dell, 32 GB of RAM, 64-bit op system, processor: Intel (R) Xeon (R) CPU x 5670 @ 2.93 Ghz 2.93 Ghz (2 CPUs).

    So far I had worked on many projects with no problems and then a few weeks ago, project crashing non-stop. The problem has been resolved when I got rid of all the MP3s and diverted to RAM. Once again, it was a problem that I had not in the past and I don't remember changing anything whatsoever.

    Now, it seems that it is impossible for me to export/rendering a project in a Quick time or same AVI file. If its quick time, I get this message: unable to make failure of After Effects error one module output. The file may be damaged or corrupted -1610153464 and if I am trying to export with AVI I get this message: cannot open projects in the background AE 26: 142)

    What is happening with the various projects.

    I have read the forums on hearing that the problem may be a Bug with quicktime and H.264? I never had a problem with it before, but even once when I try to export AVI I get this error message:

    Cannot open projects in the background AE

    I have a feeling that it is associated with quick time. I uninstalled and reinstalled QT, but still not the problem. It will open the old QT files without problem. I tried to download an update of the correction of a bug as a proposed post but I think I have the final reason why it did not work.

    This project has a couple of quick media files H.264. Do I need to convert? They are the cause of all this?

    I'm sorry, I really tried to seek answers in the forums before contacting you here, but I can't find a reason for all this mess, which again appeared a few weeks without any problems for months... If someone can point out an area where I can start looking, I would really appreciate it. Thanks in advance.

    QuickTime H.264 is terrible. Do not use it.

    Use the AVI file, you have created in your Adobe Media Encoder and use the parameters of H.264 there.

  • 'Cannot open file because the disk is not available' Mac

    I recently changed the selection of Photoshop (CS6) Scratch disk to the boot drive by default to one of the other internal drives in my MacPro (OS 10.6.8).

    When I restart Photoshop (CS6) I get the message:

    "Cannot open file because the disk is not available"

    and Photoshop will not start.

    I then restart Photoshop with 'Control - alt - shift' keys

    (suggestion to <>)

    and reset preferences that allows Photoshop to return.

    (Reset preferences returned the boot drive to drive work status.)

    I have an another MacPro, the - same 10.6.8 OS and Adobe CS6 - and I don't have this problem of allocation of work disk.

    What happens with a MacPro which prevents me from selecting one drive other than the boot drive working Photoshop

    Probably a permission problem.  Run the Apple disk utility to repair permissions.  If this does not work the glance to the non bootable drive and check "Ignore permissions..."  Open the window Info Finder and it came inside.

    Was the HP works well before game console? If Yes, then do you remember any hardware/software changes, after which the problem started?

    Method 1: I would say you put the computer to boot and then check if the problem is caused by any third-party application.

    Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.

    Method 2: I would say as you uninstall and reinstall the HP game console and check to see if it helps:
