Compatibility mode error

Ok, so every time I open up iTunes I get an error message reading "iTunes.exe has been set to run in compatibility mode for an older version of Windows. For best results, turn off compatibility mode for iTunes before you open it." I have compatibility mode already turned off (and, yes, all the boxes are unmarked). I have even tried different times with the "run as administrator" box checked and I still get the same result. Is there something else I'm missing or is it just Windows 7?

I have compatibility mode already turned off (and, yes, all the boxes are unmarked).
The next thing to check on is a errant registry entry. See the labnut2 instructions from the following post:

Windows 7 Compatibility Mode Error when Compatibility Mode is OFF

I have Windows 7 Ultimate 64 bit on my Dell Studio XPS 16.
When I launch iTunes, I get the "iTunes has been set to run in compatibility mode. For best results, turn Compatibility Mode off" message. The program is NOT set to run in compatibility mode. The program works fine otherwise but I don't understand why I get this error message.
Background: I ran the installer as an administrator and the program is set to run as administrator. I've tried reinstalling twice.
Any ideas?
Thanks.

First head into your Compatibility tab and check to make sure that all the checkboxes are are unchecked. (Having any checkbox whatsoever in there checked can cause a compatibility mode message, including "run as administrator".)
If all your checkboxes are unchecked, and you're still getting the same compatibility mode error, you may have a problem with a rogue registry entry that can hit some folks in their iTunes and/or QuickTime on 64-bit systems. For a discussion on how to get past that (on Windows 7 64 bit), see RandomBehavior's post in the following thread:

Compatibility Mode Error when NOT in compatibility mode

I have a Dell Studio XPS 16 running Windows 7 Ultimate (RTM, not RC). iTunes installs fine but I get this error when I open it:
"iTunes.exe has been set to run in compatibility mode for an older version of Windows. For best results, turn off compatibility mode for iTUnes before you open it."
Once you click OK, the program runs fine. But this still bothers me. Thoughts? Under the application's properties, compatibility mode is NOT selected.

I'm getting the same thing, if you find a solution let me know!

IE8 compatibility mode error?

Greetings,
I built this page a few weeks back: http://www.brightwork.com/overview and recently I've been told there's a bug where all the text on the first page wont display. It merely appears as Undefined. From other errors I've weeded out I know that Undefined means that the text files those batches of text are loading from are not being loaded properly, however my preloader shouldn't allow it to start without those files being loaded.
I have been unable to repeat the bug, but apperantly it has something to do with having Compatibility Mode disabled. Can anyone who goes to that link tell me if it works for them, and if you have any ideas why it might be breaking those other times please tell me!
Cheers

Hi,
do you have a solution for the problem? We have actually a similar problem with locked IE8 when using a zoom factor > 100% (it's a customer WD4A).
Regards,
Steffen Brauner

Internet Explorer and compatibility mode error

Whilst using DMXZone's HTML5 video player, it throws up a problem on some PC's stating there is an error and states to run in compatibility mode. Is there a line of code I can insert into the page that forces compatibilty mode to work? The client insists that they don't have to explain to every customer what to do.
Thanks

'If the problem is with IE8 or below, this is because they do not support html5, the html5 shiv/js file if you are using one, only allows css styles to be applied and gives no other functionality.
PZ'
OK - thanks for looking into it for me.

Compatibility Mode errors since I installed 7.5

I am running Vista 64 bit, 8 Gigs, of ram, 8800 GTX, after installing 7.7 quicktime, I am now getting
Quicktime Player requires Windows 2000 or later.
Please sure compatibility mode is disabled in the Compatibility tab of the properties for QuickTimePlayer.exe
for 1 thing Compatibility is turned off on this, even when I turn it on and off it states the samething, I did not have this problem until I installed the latest version of Quick Time Player, any info on how to fixe this would be supurb

for 1 thing Compatibility is turned off on this, even when I turn it on and off it states the samething
Head back into the Compatibility tab. Make sure none of the boxes in there are checked (any box checked in there can produce a Compatibility mode message).
If any other boxes were selected, and you deselected them all and clicked OK, does QuickTime launch without the compatibility message?

Itunes says to turn off compatibility mode? don't know how, help!!

I just downloaded the itunes 9.2 update this week and since then have been prompted to turn off compatibility mode every time I open itunes. I don't even know what that means or how to turn it off, (never seen this message before). Does anyone know how to turn this mode off? I've searched the progam files and all the options and can't seem to find anything.

There's instructions on how to change compatibility mode settings for iTunes in the following document, although there's a couple of additional quirks you need to watch for.
When you get to *step 8* make sure that no boxes are checked in the compatibility mode tab (not just the compatibility mode box itself ... having any box checked in there can cause a compatibility mode error message).
[iTunes for Windows: How to turn off Compatibility Mode|http://support.apple.com/kb/TS1489]
If none of the checkboxes are checked, and you're still getting a compatibility mode message, that's usually caused by an errant registry setting. For troubleshooting advice on that possibility, see Random Behavior's post in the following thread:

iTunes for Windows: How to turn off Compatibility Mode

TS3299 opticals drive disappeared in my Windows 8 computer. After 1-1/2 on the phone this was corrected but now my Itunes don't recognize the drive. Error message stating registry errors. I tried running in windows 7 compatibility mode that don't

Purchased a new Ipad for my wife and integrated it with my windows 7 system and Itunes and made it through. Was able to sync and bring pictures, contacts and bookmarks over. Not to say it was easy because I never used any Apple product except my Ipad and Itunes. Really enjoyed using the Ipad and was thinking of getting a new Iphone this week being my contract is up.
Then the trouble began I bought a new windows 8 system after having trouble with my old hard drive. I have finances and Tax programs I use that I thought would be easier to continue using windows rather than trying integrating past years Quicken & Turbo Tax information into a new Apple system.
Well now I'm sorry I bought the new windows 8 system. First all my optical drives disappeared when installing itunes. After spending 1-1/2 on the phone with a service rep and finally was able to see my optical drive I thought everything was OK. Then more trouble. When I open Itunes I receive an error message that says my Itunes no longer recognizes my optical drive try reinstalling. I reinstalled 10 times and tried compatibility mode and the end result is my Itunes no longer could burn Cd's. I had this problem if I'm not mistaken in the past with ME system back many years ago. And did not want to go through this again but here I am disgusted once again.

I finally got my nano working (no thanks to Apple, hmpf!) and it's running fine with 1.0.2 now. For those with similiar problems try this:
+For Mac, you need to:+
+1. Downgrade to firmware 1.0.1 by deleting the files iPod_26.1.0.2.ipsw and iPod_26.1.0.2.ipsw.signature (are in the folder iPod software updates somewhere on the harddisk)+
+2. under Settings in iTunes you have to disable automatic download of updates, then restart iTunes.+
+3. Enter Disc Mode by holding menu & select for about ten seconds, then pressing play/pause & select for another ten seconds.+
+4. reconnect your nano to Reset, and when iTunes prompts to update, just don't allow it to look for updates and then reset with fw 1.0.1.+
I'm supriced Apple support didn't tell me about this? This worked great and is a very fast fix. I can't believe Apple got me to reinstall the whole OS, which didn't even solve it btw. USB 1, blah! Yeah right..

Error - iTunes Library .iti file is locked on a disk or you do not have permission for this file. I can open itunes in the compatibility mode for Windows XP Service Pack 3 ???

In Windows 8 I received the error iTunes Library .iti file is locked on a disk or you do not have permission for this file. I can open itunes in the compatibility mode for Windows XP Service Pack 3.
I've tried changing permissions and sharing - nothing seems to work. mat be a Windows 8 issue???

You also need to make sure you have both read and write permission for the file, or for the whole iTunes folder for that matter. That's also done in Get Info for the file or folder concerned.
Read the part about changing permissions on the iTunes folder in: https://discussions.apple.com/message/11583914

Windows 8.1 and VS2012 SDK get error "Windows Program Compatibility mode is on. Turn it off and then try Setup again."

When trying to install VS2012 SDK on Windows 8.1 get the error "Windows Program Compatibility mode is on. Turn it off and then try Setup again."
See my blog C# Bits | Twitter @sjnaughton Always seeking an elegant solution.

Rick, Have you had any success with this? I'm also trying to run the tfs_VssUpgrade.exe tool on my Windows 8.1 machine and getting the same exception. Greatly appreciate any insight if you were able to get past this issue! Thanks, Steve
Same issue here.
This MS connect thread
is interesting however.

Hello Alxandr,
Thank you for taking the time to submit this issue to Connect. This is a known issue with Windows 8.1 RTM and it will be addressed in a future update of Windows 8.1. In the meantime, you can typically rename the EXE to get it to work correctly.

Chart causing error 1009 when enabling compatibility mode in Flash Builder 4

Hello.
I'm trying to use the chart components in Flash Builder 4. I'm using Flex SDK 4, but had to turn on the "Flex 3 compatibility mode" for some off-topic reasons.
I simply created a new application and copied the code from the DateTimeAxis class example: http://www.codigoactionscript.org/langref/as3/mx/charts/DateTimeAxis.html#includeExamplesS ummary
When running the example, the following error is reported (sorry, it is in italian: it's simply the "null object" error):
TypeError: Error #1009: Impossibile accedere a una proprietà o a un metodo di un riferimento oggetto null.

at mx.managers::LayoutManager/doPhasedInstantiationCallback()[E:\dev\4.0.0\frameworks\projec ts\framework\src\mx\managers\LayoutManager.as:1072]
Is there a solution to this bug? We really need to use charts AND keep the Flex 3 compatibility mode.

I use SDK 4.1 but I also get the error: (Flashbuilder 4.0.1 in Flex 3 compatibility mode)
TypeError: Error #1009: Cannot access a property or method of a null object reference.

So I guess it is not solved....

ESSO Error with IE 9 Compatibility Mode

Can anyone help? We are implementing eSSO with OIM 11.1.2.. When testing the system, we receive an error that Compatibility Mode should be turned off. We can turn off Compatibility mode and the user can access the site fine while they are logged in. But when we try to access the site from a locked screen, we get the following error. "The current compatibility setting is not supported. Disable Compatibility View before running this web page." If you click OK, the page loads fine.
We have applied GPO's to force the Compatibility Mode Off.

Hi JimmyWeise,
Can you try to download Microsoft SilverLight Browser Plugin and install into IE9. Then try to validate the same.
