The Install Mac OS X icon disappears on the bottom of the dock every time I click to install. Why is this happening?

I put the disc in, and the box pops up with the "Install Mac OS X" icon. I click on it and I see it pop up on the dock but then immediately disappear. Nothing else happens, no matter how many times I double click on the install icon. I currently have a Mac OS X 10.5.8 and am trying to install this Snow Leopard 10.6.3.
thank you!

Make sure your Mac meets v10.6 Snow Leopard's requirements > Mac OS X v10.6 Snow Leopard - Technical Specifications
If your Mac can upgrade to v10.6, make sure there's enough free space available for the installation.
Right or control click the MacintoshHD icon on your Desktop then click Get Info.
From the Get Info panel, make sure there's at least 15% available disk space.
And you may need to repair the startup disk before installing Snow Leopard.

The sync fucntion resets every time I restart firefox. Why is this happening?

I open Firefox and set up sync. I have an existing account. When I close Firefox and then open again, the sync function is reset and I have to set it up all over again.

Changing the settings so that saved passwords are not deleted when Firefox closes solve the problem. I'm not using a master password so I don't think that is an issue.

When I send out mail from MS Outlook enterprise account in the office to my Mac at home they are received as "winmail.dat" files. Even if I perform a "save as" to the correct file name the file format is still not recognized. Why is this happening!?

Only one track is downloaded per album on itunes on my iphone 5. Every time I download a new track it deletes the previously downloaded track on that album. Why is this happening and how can I switch it off?

Most YouTube content requires the Flash plugin. Sometimes it's necessary to uninstall then reinstall that plugin.
Uninstall the Flash plugin then reinstall new > Troubleshoot Flash Player | Mac OS
Very important to uninstall the currently installed plugin first.
Now launch Safari and try a video.
If you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.
And check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to: Open in 32 bit mode is selected, deselect, quit then relaunch Safari.
You may also need to delete the cache associated with Safari .
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy/paste: ~/Library/Caches/com.apple.Safari
Click Go the move the Cache.db file from the com.apple.Safari folder to the Trash.
Quit and relaunch Safari. Try a video.

Sometimes after creating an event folder on iPhoto, all my pictures in that event will be gone the next time I open iPhoto. Why is this happening? Is there a way to retrieve the missing photos?

Sometimes after creating an event folder on iPhoto, all my pictures in that event will be gone the next time I open iPhoto. Why is this happening? Is there a way to retrieve the missing photos?
Most events I make on iphoto will still be there the next time I open iPhoto, while other event FOLDERS will be there, but pictures in it gone.

What version of iPhoto? Assuming 09 or later:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places 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.

HT201209 EVERY TIME i REDEEM AN ItUNES GIFT CARD, MY PREVIOUS BALANCE DISAPPEARS! HOW MANY DOLLARS I HAVE LOST IS UNKNOWN TO ME! WHY IS THIS HAPPENING?

Today I redeemed a $15 gift card. I had .95 on my account from a previous redemption. As soon as I redeemed, the balance disappeared, and left my balance as $15. I noticed this happen before several times and assumed that Apple was keeping track. I dont think so, I think I am being ripped off!

Because your iTunes Store credit can't be spent on content for anyone else or transferred to anyone else's iTunes Store account.

My ipad won't turn on. Have tried to reset by pressing the two button at the same time. It work. Why is this happening? For the first time it happened to me after using the ipad 4 running on ios 7, for almost a year and a halftime

My ipad won't turn on. Tried to reset and it work. I'm using ipad 4 with ios 7 and this is the first time that this happened to me.what is wrong with the ipad?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

How can I get App Tabs to automatically load a fresh version of the page every time I click on them?

I like the app tab feature and am using it for sites that I visit frequently, for example, weather sites. The problem I have is that when I click on say http://www.metoffice.gov.uk/weather/uk/ta/arbroath_forecast_weather.html I get the site as it was the last time I used it. Today this meant I got a weather forecast starting from 2 days ago, not from today.
I can get round this if I remember to "Reload" every time but I'm guessing that is not the way app tabs were intended to work.

One of these two add-ons should do that:

When I open Firefox or click a link, Firefox opens several, duplicates of itself or the clicked link. Why is this happening, and how can I fix it?

For the last 2 days, each time I open Firefox, and each time I click a link, I get duplicates open pages of which ever thing I clicked. I have had no Windows updates in the last few days, so it cannot be that, as a cause.

I am having trouble with my mac book air. I think I have a virus because every time i click on a link it opens up popup windows and other things. How do I reset the computer?

I'm not very good with computers, so I need to be told how to do this as simple as possible. Please help.

It's not a virus.
You may have inadvertently installed adware. Eradicating it is simple and you don't have to download or install anything to fix it. For an explanation or how this may have occurred, how to avoid it in the future, and for one possible solution read How to install adware.
