Opening application for the first time warning keeps coming

I've installed VLC player and amongst other media files set mp4 to automatically open with it. When I double click a mp4 file it asked 'You are opening the application 'VLC Player' for the first time' etc. Pressed ok. After that it didn't ask that any more.
However, every time I reboot my Mac and double click a mp4 file again, I keep getting that 'You are opening the application 'VLC Player' for the first time' warning popup again the first time I want to open a media file. Then it's gone again, until I reboot my Mac again.
Every time I reboot and want to play a media file I always get that 'first time' popup. It only happens with VLC Player. I've uninstalled it completely and reinstalled it again, but that 'first time' popup for VLC Player keeps coming every time I reboot and upon the first time I open a media file.
How can I fix that?

Did you copy VLC to Applications folder? When you download VLC, you get it in a DMG file, that you have to open, and here's VLC. However, you don't have to copy the VLC copy you find in it, but you have to drag the VLC icon to the Applications icon:
Then, drag the VLC DMG file you find in the Desktop, drag it to Trash and delete the VLC installer from Downloads folder. Finally, open VLC from Applications folder

"You are opening the application----- for the first time" error

I've seen a few people post about this from as far back as 2005 but I haven't found anything that worked for me. I believe I started having this problem after upgrading to Snow Leopard.
When opening an application, most often Microsoft Office by opening a specific document/file, I get the warning that I'm opening the application for the first time. This is mostly an annoyance but I don't know how to get this error to stop coming up. I saw a suggestion to delete caches and make sure the application was set as default for that file type; these haven't solved the problem yet.
Thanks!!

Thanks for the reply, unfortunately I'm not sure it helped. I did recently trash a couple caches, but this was after the problem had started. I found an old post that suggested the cache might be corrupted and that it would be a good idea to trash it.
The link you posted notes that the deleted cache could cause that problem, but I would think a new cache would be created and it would be resolved. Is it possible I have a setting that's erasing it? How would I change that? It also sounds like in the link you posted that theMacMac's problem eventually went away without explanation.

I downloded iphoto 11 9.2 and when opened it for the first time and the program started to update my iPhoto library the file got corrupted. That has happened in the two macs I have (both of them rather new and updated to last Lion version 10.7.2).

I downloaded Iphoto 11 9.2 from the apps store (was on iphoto '09 before version 8.x) and when opened it for the first time it tried to update my photo librery and ended up corupting it to the extreme that I had to get a backup from time capsule and downgrade my iphoto version. I spent yesterday 6 hours at the genius bar in an apple store and they were not able to provide me with any other solution. In the emantime, I have to forget about about photo streaming... Any idea, is this a bug that somebody knows how tp fix?

In fairness, this isn't an issue in iPhoto 11 but one in your Library. Some file or other in there is damaged and that's what causes the crash during the upgrade.
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Known Issue while running Adobe Story desktop application for the first time on Mac OS 10.8

You may encounter the following error message while running the Adobe Story desktop application for the first time on Mac OS 10.8:

Does your user account name really contain a single quote? If so, it looks like the quote is getting eaten by one of the build scripts, which is resulting in a file path that doesn't exist.

Hi,John,Thanks for your quick reply.
I think after install Hyperion Planning,at first time can't create application in this address:http://localhost:8300/HyperionPlanning/ ,usually create it in workspace.
Is the address you said different from http://localhost:8300/HyperionPlanning/?
thanksI gave you the address to create a planning application directly - http://localhost:8300/HyperionPlanning/AppWizard.jsp
Notice the AppWizard.jsp on the end.
If it version 11 you will be able to create your datasource from that location, if it is version 9 then you will have to create a datasource first from the configuration utility.
Cheers

"Application opened for the first time" warning after every reboot

Hello, I have a problem with Lion 10.7.5. The system does not remember that I already opened applications before. After every reboot, every time I open an application it displays the warning as if it's the first time I'm opening it. Anyone knows how to solve this problem?
Thanks in advance for your help.

In my case, the problem disappeared after I installed the 10.7.5 supplemental update.

Download music from ipod when opening iTunes for the first time?

I just got a new iMac at work and the first time I plugged my iPod into the comupter to charge it up it opened my iTunes and then started to download all my songs from my iPod. Being 7am I wasn't thinking properly and pressed cancle to stop the download, then I remember I have 500GB free memory and why shouldn't I have my music on the computer. The problem is I can't get it to download the music again. I know you not ment to be able to download from your ipod but that is what happened.
I have tried completely uninstalling iTunes by removing the icon in Applications and in the User>Music folder to get the same result but it makes no difference, where I once had a couple of meg's worth of music which had started to download I have none. Can somebody please explain to me how this happened and how I can revert iTunes back to how it was before I opened it so I can quickly download all my music onto my computer??

We'll unfortunately that's not true. I had though that was the case as well until this happened. I wasn't sure if this a new feature that iTunes had for when you first attach an ipod to a new iTunes (where you need to go through the terms and conditions, and set up your settings at the beginging).
I have downloaded very little from the iTunes store and the things which got downloaded were some funny adds which I had converted and put on my ipod as well as some AC/DC, some Beatles and a collection of 179 other songs (I'd be lucky if I've downloaded 5 songs in my life from iTunes). Before deleting everything in the hope that I could do it again I even played a couple of them in case all it had done was take the album artwork or something. But they all play fine and none of them were ones I had downloaded.
Does anyone know what's happened and how it can be repeated?
As to the other ways of getting music of your ipod I'm aware of them and have used irip in the past without any problems. I know how to do it that way but now that I have been made aware of this other way I was wanting to clear up how it happened and if it can be repeated, say if I was to reinstall iTunes.

When I open FF4 for the first time after starting the computer it is very slow to load. From then on it loads normaly.

I have an HP Pavilion DV9000.

I had this problem too. Not just with FF 4 but also previous versions. For that and other reasons I decided to by an SSD and install windows and all the programs on there. That worked fine except for firefox. Boot time is much faster (2o secs) and programs (from the startup folder) are loaded almost immediately after the desktop comes up. However firefox still took 90 seconds to load. After some trial and error I disables in the registry prefetcher and superprefetch (I am running windows 7, no SP1). Then I restarted my computer twice. The first time firefox did not load any faster but at any subsequent startup firefox starts in a few seconds. In fact some times it is so fast it comes up before the wireless network connection is established. HTH
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/SessionManager/MemoryManagement/PrefetchParamaters/EnablePrefetcher --> 0

You are opening app...for the first time - warning???

I get this message sometimes when I double click a file to open an application even though the app has been used innumerable times? ANyone know why?
Thanks - JAY

Jay,
I have a copy of OnyX but I reserve it for troubleshooting.
As stated by Wade, and presented by Dr. Smoke in Maintaining Mac OS X (Maintenance myths) most maintenance applications are in fact troubleshooting tools.
I use Macaroni for regular automated (set it and forget it) maintenance and also for cleaning language-specific localized files for languages I do not use.

I keep getting a notice on opening Firefox for the first time saying I need to update and when I click on it the thing keeps saying it is connecting. It does not look like a real Firefox request so I've been closing it.

Every morning when I turn on my computer and start Firefox I get a notice that I need to update Firefox. When I click to do so it just keeps running saying "Connecting".
I do have a Print Screen of it and would send it if you want.

If you have problems with updating then best is to download the full version and uninstall the currently installed version.
You may need to remove the Firefox program folder to do a clean install of the new version.
Do a clean (re-)install:
Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Do not remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

I just opened iWeb for the first time in several months and the fonts have changed and are garbled in the headers. Is this a result of switching to Lion, and does this mean I have to go through all 70 pages on my site and manually change them back?

The text on my pages are messed up. The letters in my headers are on top of each other and the letters in the body of my pages have no separation between them. Is this a result of switching to Lion? (I haven't opened iWeb in several months, since before I installed Lion.) Any ideas of how to fix this, or do I need to go text block by text block and page by page to put it back right? Thanks.

In Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
For opening your domain file in Lion or to switch between multiple domain files Cyclosaurus has provided us with the following script that you can make into an Applescript application with Script Editor. Open Script Editor, copy and paste the script below into Script Editor's window and save as an application.
Just launch the application, find and select the domain file you want to open and it will open with iWeb. It modifies the iWeb preference file each time it's launched so one can switch between domain files.
do shell script "/usr/bin/defaults write com.apple.iWeb iWebDefaultsDocumentPath -boolean no"delay 1
tell application "iWeb" to activate
You can download an already compiled version with this link: iWeb Switch Domain.
WARNING: iWeb Switch Domain will overwrite an existing Domain.sites2 file if you select to create a new domain in the same folder. So rename your domain files once they've been created to something other than the default name.
