Quicktime 7.5.5 not installing on MacBook Pro

I have downloaded QuickTime for Leopard 7.5.5 and run the install. I follow all instructions including restarting after "Installation Successful" notification.
After restart QuickTime is nowhere to be found, not in Applications and not showing in the sofware section of "About This Mac". Searching only locates QuitckTime help files.
I have searched the QT support forum and cannot find an answer.
I have a first generation MacBook Pro 1.83 ghz, 2 gigs of ram and am running Leopard. I have run software update and all software is up to date.

I had to update my QuickTime and downloaded 7.5.5 and ran the install. I'm having the same problem. Suddenly QuickTime has disappeared from my computer. When I had an earlier version of QT, my iTunes Movies wouldn't play. Now the Movies on iTunes play, but I cannot open any video files from my camera--.AVI files. This is my first time posting on one of these forums. Thank you for your help.

10.5.4 retail install DVD will not install on macbook pro

I have a retail OSX Leopard DVD
version 10.5.4
2Z691-6232-A
I am trying to do a clean install of the OS on a Macbook Pro 5,2
Intel Core 2 Duo 2.8GHz/ 4GB of memory
The machine is currently running 10.5.8. The OS currently installed on the machine in question was originally installed from the same disk.
This is a company machine & the company I work for purchased the DVD and the changing the startup disk has always worked in the past.
There shouldn't be any sort of sketchy I borrowed this disk from my step-brother's cousin's wife.
The disk mounts on the desktop.
When I change the starup disk to the DVD and restart nothing happens. The system restarts but does not do it from the boot DVD.
When I hold down the c key during reboot the machine goes into a booting loop but never boots.
startup tone/30 seconds(no apple screen)/startup tone, etc.
It seems like there is a problem with the DVD even though it mounts on the desktop.
Any suggestions?

Thanks for responding.
I'm sorry I wasn't clear. The disk was never borrowed.
The disk was bought by a business. Only used by the one business and it didn't come with a computer because it was bought online by one busines who has always kept the disc in their possession. We have used this disc numerous times to reinstall 10.5.4 on a number of our machines.
The disc in question is black like the box that is comes in. In my experience OS discs before 10.6 (especially retail discs) are not linked to a machine so this has nothing to do with the wrong disc.

Wacom intuos5 driver not installing on MacBook Pro 2009 ML

Hi,
I recently bought a new Wacom graphics tablet - intuos 5touch. Very expensive and supposedly very good. But I cannot install this on my MacBook Pro 13inch 2009 running mountain lion 10.8.2. I have the latest driver fromwacom and the installation process runs all the way through to 'validating packages' and then fails for no given reason. On Console there are a long list of errors but not sure if these are for the installation or other reasons. I have deleted and reloaded the driver and I have cleared my hard drive and clean installed mountain lion from the apple store with a time machine backup. I am extremely frustrated. I have been using my macbookpro for 3 years with no real problems but the latest os releases seem to be causing everything to run slow or not work. I have checked the hd for errors and repaired everything which needs doing. Does anyone have any suggestions? I cannot afford to replace my mac, it was expensive enough and should really last longer than 3 years.
Any help gratefully received
thanks
Helen

Ok, this is my latest update. Having spent 1.5 hours in the apple store having a full diagnostic check done - nothing obviously wrong - I have done the following:
Replaced the old drive with a new ssd. Added 4gb RAM to give a total of 8Gb. Done a full reinstall of mountain lion by download and NOT restored from time machine.
The Apple tech suggested that I either had a bad drive or there was a software conflict somewhere. I restored from my time machine backup onto the new drive and still couldn't install, so that told me it was software not hardware that was causing the problem. I then erased my new drive and downloaded mountain lion from the app store from scratch and reinstalled. Before doing anything else I downloaded the driver from wacom and - hey presto - it installed! Halleluia!
The conclusion is that I had either a corrupt file or setting somewhere which was causing a conflict with wacom and not allowing installation. If your disk is ok then I suggest you clone your hard drive to time machine or other backup, erase the hard drive, reinstall mountain lion from disk or download and then before doing anything else install wacom's driver. If this installs then you need to decide what to restore from your backup - the apple tech suggested not restoring settings and users as these areas are where corruptions can occur.
Tedious but it works, and my wacom intuos 5 is now working! I hope it's worth it!
Hope this helps.

Mountain Lion not installing on MacBook pro 17inch

I have downloaded without any issue and followed the prompt to install. The install start and goes on for 35 minutes with the progress bar moving. So it is doing something. Then it is getting to the end with the following message: install failed. OsX could not be installed on your computer. The installer encountered an error that caused the installation to fail. Contact the software manufacturer. Click start to restart your computer and try installing again.
I have tried 6 times but not working. The I wanting to restore from backup using the utilities from the menu bar "Restore System from backup" it will do the same and. Go on for 35 minutes and get to the same screen "install failed" what should I do now.

Having read several posts on this subject it seems to be very hit and miss for some people, but I think on the whole it is only a few who are affected.
I find it very difficult to believe that a Mac cannot be taken back to Snow Leopard by performing a complete fresh install using the install DVD that came with that machine, or a retail edition disc. Mac OS does not alter the firmware during the install as far as I am aware, so the hardware should be the same as it was originally before the install.
The only thing I can think that might prevent a successful install might be if the system files have been altered by software installers, the Mac OS installer might be confused, or if the permissions have not been set correctly then the installer might not be able to overwrite or set up certain files. That is why a clean install should (in theory) always work on compatible hardware, then a restore from a backup or Time Machine would be all that is required to bring back the user's data. Formatting the hard drive may be a necessary step if it is not working as expected, this can be done from the Utilities when booted from the install media (or Lion recovery thing).
I didn't have a problem installing Lion or Mountain Lion on my Late 2011 17 inch MacBook Pro, but before installing made sure I created a USB flash drive (8GB) from the downloaded installer using the little trick which is around on the internet. If the installation had bailed for any reason, I definitely did not want to have to download several GB all over again.

Pages purchased via Apple Store not installed in MacBook Pro

Hi, I bought a new MacBook Pro recently (Mac OS X Version 10.7.4). I purchased Pages via Apple Store and click the 'INSTALL' button. After that I found that Pages is never installed in my computer (I check the applications folder and could not find pages installed in it). Can anyone help me out.
Thanks in Advance.
Dina

Dear Jerry,
Thank you for the reply. Sorry for the delay in replying.
You are right. There is an application in MacBook Pro (Lion) with the name App Store.
I purchased the software using this application only.
I am sorry. I did not purchase it online in apple online store. I purchased online through this application (App Store).
Finally, I figured out. I had a previous installation of iWork in my MacBook Pro (Lion). I read in the internet
about this and came to know that I should go to Library/Preferences/ and then delete Com.Apple.iWork.
I did this. Rebooted the system and then tried to install. I was successful and now Pages is installed.
Thank you very much for the help.

The iMovie 11 update I just bought from the App Store will not install on Macbook Pro

I have a Macbook Pro and I have iLife 09, I updated all the other iLife 09 apps to iLife 11 (iPhoto, Garage Band) . So I bought the update for iMovie yesterday and it seems to downloaded fine but when I click the install button it doesn't do anything. Can you guys point me in the right direction to get this installed
Thanks

You have a corrupted old system. At the very least you need to repair the hard drive and permissions before trying to install Mountain Lion. However, this my not be sufficient. You may need to reinstall your old system before trying to install Mountain Lion.
Of course it would be more useful were you to provide the full information on the error message and what OS X version you currently have installed. Also check that you can install Mountain Lion on your model:
Macs that can be upgraded to OS X Mountain Lion
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
Xserve (Early 2009)

Leopard will not install on Macbook Pro

I have been reading all the posts here and am very surprised at all the issues. I expect this out of Micrsoft not Apple. I have close to 6 hours into this install and here I sit typing this in Tiger. I had the failed install where it tells me that I have to format the drive. I spent 1 1/2 hours on the phone with tech support and all I really accomplished was learning a few keyboard shortcuts (I'm new to Mac since April of this year). Disk utility in Tiger says the drive is fine. Disk Utility in Leopard Installer says it is not and needs a minor header repair. Repair disk doesn't fix it. Any ideas? I did a repair any way. I verified disk permissions and had to do a repair. Tried Leopard again with the same result. The read me first file states you cannot do an upgrade on a UFS formatted volume. Mine is HFS. The following is what it reads at the bottom of Disk Utility:
Disk Description : Hitachi HTS541612J9SA00 Media Total Capacity : 111.8 GB (120,034,123,776 Bytes)
Connection Bus : Serial ATA 2 Write Status : Read/Write
Connection Type : Internal S.M.A.R.T. Status : Verified
Partition Scheme : GUID Partition Table
I have 77g of storage space left so that is not it. I am new to Mac so I am not familiar enough with the file structure to get all my files. Even if I was, after the install attempt, I cannot see my network drive to do the backup. Hooking the drive directly to my Mac initiates a message to format my external drive. I have a ton of info on it so I have been backing it up to my Vista machine for most of the morning. Any ideas?

After backing everything up and attempting a clean install, I finally got it to run, but not without a fight. I started teh install and had to erase teh drive. I expected that this time. The erase was successful and it continued on. About 5 minutes into it I got a new error that stated that it failed because it could not create a folder on the volume. I restarted the machine and held down the "C" key on boot. Leopard installed without a hitch. Running nicely now. I will say that I am disappointed at how much trouble I had to go through to get to this point.

Mavericks will not install on MacBook Pro

I've made multiple attempts to install Mavericks. I get to the reboot stage and it cycles indefinitely. Eventually, I shut down and restore from my external backup drive. I'm running 10.7.5. I've decrypted the Filevault. Done multiple Repair DIsks and Repair Disk Permissions. Never works.
Any ideas?

I'm not sure what you mean by this phrase.

UbikReader update in App store but not installed on Macbook Pro

I have an update showing as available in the App Store (UbikReader, by UbikLabs), but I have never installed this application on any of my Macs. I have used both Spotlight and EasyFind to search my macbook for UbikReader & UbikLabs -- and nothing is found.
If I click the Update button next to the app, it will autofill the credentials for the app it would have been downloaded with ([email protected]). A quick google search shows that this account has been compromised and the password is floating around on the internet. I'm assuming someone/something attempted some sort of an install but it never completed.
My question is this.... if I don't have the app installed, I can't delete it; without using the widely available credentials, I can't Update the app to remove the notification... How can I remove any left-over from an application that doesn't appear to have been installed on my cmputer and/or my account? I would like for it to stop showing up as an available update in the App Store.
Thanks!

I found the solution for my issue in a similar post: https://discussions.apple.com/message/21055428#21055428. The recommendation worked for me and the App Store is no longer showing an available update for UbikReader. Thanks to seventy one for the recommendation/fix!
"You could try reindexing your HDD. The MAS uses the Spotlight indexing in determining what apps need updating. Go to Systems Preferences / Spotlight/ Privacy; add your Hdd to the list then remove it from that list. Spotlight will then reindex your HDD."

Applications not installing on macbook pro

I click install app and it never actually installs it. all it does is the loading circle thing in the top left of the app store window

Quit the App Store if it's open.
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
~/Library/Caches/com.apple.appstore/Cache.db
Click Go then move the Cache.db file to the Trash.
Restart your Mac, and elaunch the App Store. Try installing an app.

Hi,
From the Apple menu click on App Store, then select Software Update.
Click the top Store menu and then on Reload page and install any listed HP or Apple update.
Once you are done, try adding the printer under Printers & Scanners again, then follow the software update once again to ensure the latest drivers were installed.
Please check if that may work, if the same persists try installing the drivers manually from the following link:
http://support.apple.com/kb/dl907
Once you are done try adding the printer from Printers & Scanners once again and check for any difference.
Please let me know the results.
