Failed to verify the preflight file. It is not signed by Apple.

This morning I was able to download iMovie, iPhoto and iBook Aurhor without getting this error: Failed to verify the preflight file. It is not signed by Apple.
However I am still getting this error when trying to update Numbers, Keynote, Pages and Aperture 3.5. I am starting to think this all maybe caused by a server overload with Apple.
Anyone else receiving this error: "Failed to verify the preflight file. It is not signed by Apple" when trying to update Aperture 3.5?

Hi William,
What worked for me was changing the certificate preferences in Keychain Access (open Keychain Access app and then go to preferences).
I just changed both of the first two options to 'Best Attempt', they were originaly at 'Require if certificate indicates'.
Then I go to "Purchased" and from there I downloaded the updates, this time without any problems.
Hope this Helps.

I try to purchase pages (after upgrading to maverick) and get this message: Failed to verify the preflight file. It is not signed by Apple.

I try to purchase Pages (after upgrading to Maverick OS) and keep getting this message:
Failed to verify the preflight file. It is not signed by Apple.
How to I get past this? I cannot find anything referencing preflight file. Who can identify this?

Back up all data.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
From the menu bar, select
Keychain Access ▹ Preferences ▹ Certificates
There are three menus in the window. Change the selection in the top two to Best attempt, and in the bottom one to CRL. Log out, log back in, and test.

getting "We could not complete your update. Failed to verify the preflight file. It is not signed by Apple." message when trying to update Apps via the App Store. Get similar message for download of a free app. Console message is:10/23/13 2:00:27.610 PM storeagent[310]: *** Assertion failure in -[ISCheckPreflightOperation verifyDistributionAtURL:allowsDevSign:allowsUnsigned:osVersionToBeInstalled:err or:distributionController:], /SourceCache/Pisa/Pisa-232/ISCheckPreflightOperation.m:314
Any ideas?

Similar threads solve this problem by either creating a new administrator identity, which allows one to update applications, or changing the keychain prefs to Best attempt. My issue was solved by adding a new admin user, and then updating the apps from the App store using the new identity. Under my orginal user identity the keychain app would crash when I attempted to open Prefs. After creating a new identity and updating the applications (iPhoto, etc) I found I was able to open the keychain Prefs logged into my orginal identity.

I have completed the OS X upgrade, restart etc. but when attempting to update 8 other Apps to X I get this message: WE COULD NOT COMPLETE THIS UPDATE Failed to verify the preflight file. It is not signed by Apple?

I cannot get my App Store to work. It says "Failed to verify the preflight file. It is not signed by Apple." How do I resolve this?

When I upgraded to Mavericks the other day, I lost functionality of Mac App Store. It worked fine in Mountain Lion.
Please help!

Failed to load the configuration file for the workflow

Hi experts, yesterday I created and publish custom workflow using SPD from client pc using site administrator account but today its shows error message. I tried creating new test workflows, edit and publish to think it will push a fresh SPD settings
in working condition and it works pretty right.
But the thing I noticed after closing SPD Im not able to re-open workflows and it gives the same error message Failed to load the configuration file for the workflow. This issue only happen today since day one I used SPD and all the time
Im using the same pc.
Any ideas will be appreciated.
Cheers, R2C3 ----------------------------------- starting sharepoint :)

HI
Maybe you have permission problem or there is invalid xoml murkup.
To verify this from SharePoint Designer use the following steps.
In Office SharePoint Designer, in the folder list, select the plus sign next to Workflows library to expand it
1.Next select the plus sign of the workflow in question to expand it
2.Double-click the configuration file (Workflow_name.xoml.wfconfig.xml) to open it
3.Right-click on the page, and then select Verify well-formed XML
4.Correct any errors and save the file
5.Reopen the workflow to test
Also double check that you are using SPD with the same credentials you created workflow
Hope this will help.

Marcin

Creation of Recovery Disks - 'Failed to open the following file" Error

Greetings All,
I am in the process of trying to create a Recovery Disk Set for a Client's *Satellite L300 - PSLB8A-07U004*.
While the application opens and begins the creation of the disk set, it has, three times now, failed at with the error message of *"Failed to open the following file. D:\!V5_01_07.VRP (Error Code: 020123-F1-00000000)".*
I did attempt this process the first time while the all the client's data was still loaded.
I have now done a 'Restore to 'Out of the box experience' because I thought one of those files might be the cause but, alas, the error was repeated.
Obviously this is irritating (to say the least).
I have NOT made any change to the layout or sizing of partitions.'
Any thoughts?
rampant_rhino

Thank you both for your responses.
You were on the right track.
I was attempting to use a 'dodgy' brand (SKY-Silver) of DVD-R for the creation of the disk set.
On changing over to TDK disks, the problem did NOT repeat.
Strangely enough, the dodgy ones worked great for creating copies of the set once it was completed.
Again, thanks to you both.

'failed to open the PDF file' error - Indesign CS3 on Mac

Hi,
Whenever I place PDFs that were created by any other app besides indesign or Illustrator I get a 'failed to open the PDF file' error, previously these PDFs were fine to place but all of a sudden they're not... Help?
I'm not too keen on opening in Illustrator and resaving for the rest of the foreseeable future either...

Thanks for the reminder, Scott.

After reinstalling CS6 the bridge photo downloader isn't able to read raw files and fails to convert the raw files to DNG. Previously downloaded raw files, now DNG, open up successfully in Camera Raw 7. How do I get the photo downloader to read and convert raw files. MacBook Pro with Snow Leopard. No such problem before this reinstallation.

You should install Camera Raw 4.6.

Failed to export the JPEG file

When I attempt to export a jpeg from InDesign I get the following error message, please help:
"Failed to export the JPEG file: File cannot be written.
Disc may be locked or full."
The disc it is writing to has 90Gb of memory free and I've tried knocking the quality of the export down with no success.
I am running CS6 on a fully updated Macbook Pro.
Thanks.

I'm trying to export to the hard drive on the Mac as usual, and have never had this issue before?

InDesign CS6 "Failed to export the JPEG file. File cannot be written. Disk may be locked or full."

I get this error "Failed to export the JPEG file. File cannot be written. Disk may be locked or full." when sending small (3"x3") and large (40"x60") files to a printer hot folder. Sometime if I close the program and restart it will let me export. What could be causing this to happen?
I am on Windows 7 with 4GB RAM PC.

I guess the printer is grabbing the file before it is entirely written…
Workaround: Do not save to a hot folder. Move the files after exporting to the hot folder.

Content generation error. Failed to open the InDesign file.

Hey all -
In importing an article to a folio, I just received this error:
"Content generation error.
Failed to open the InDesign file. Please confirm the file can be opened in InDesign."
The file is open right now in InDesign. I can close it and reopen it with no errors.
I've tried resaving the article to a new file. No help.
I tried creating a new folio and importing the article there. No help.
All links are good. It's a simple file with images, a scrolling pane, and some buttons that link to other articles.
Anyone else run into this problem? Any solutions?
Thanks!

Im getting this error also....?
Want to avoid inporting each artical on at a time. Need to import multiple articals at once.
Thanks.
