Required components are disabled

Hello,
I am trying install AE CS5.5 on my computer:
Windows 7 Professional
srv pck 1
Intel(R) Core(TM) i3 CPU     M 370 @ 2.40GHz
Installed memory (RAM):     8.00 GB (7.80 GB usable)
System Type:     64-Bit
Once I get to the actual install portion of the setup is states "required components are disabled" and I am unable to check the box to install. I have 12.8 GB of available space on my computer and the install box indicates that the install will only use 433 MB? Is that correct, seems small. Either way I have plenty of memory, and the box states that I have the 64-bit compatible AE, and it appears I have all the requirements from the back of the box as well. So what gives? Why could it be saying this? Mabe I don't have enough "cache"? Not even really sure what cache is or if it's applicable here but I at this point I'm just taking shots in the dark. Any help would be appreciated. Thank you!!

I'm running a Macbook Pro i7 2.66Ghz 2010 model (6.2) with 8GB of RAM and ~18GB of space remaining.
A few possibilities looking over the list:
- These models come with NVIDIA GeForce GT 330M video card, which I see is not in your supported GPU-accelerated list. Is GPU acceleration a hard requirement?
- I'm running off of a OCZ Vertex 3 solid-state drive. The requirements state a 7200RPM drive. While my drive more than meets that limit, I'm wondering if it's being detected incorrectly.
- I have swapped out my DVD drive for a second hard drive. It would not seem a necessary system requirement to have a DVD drive for the Premiere Pro functionality, but if this is a hard requirement then this may be the problem.
I can't do much about the first, but if it's either of the latter two I might. It'd be nice if the installer could tell me this directly.

'Required components are disabled' error during trial install

I've downloaded the CS5.5 trial for the first time. When I install, I see three checkboxes for install: Encore, OnLocation, and Premiere Pro. The first two are checked, but the third is unchecked with a red X to the right of its name. If I try to select Premiere Pro, I see on the right side the message: 'Required compnents are disabled'. I have no idea what this means, but it unfortunately is immutable and prevents me from installing.
Older forum posts mention this phrase and that you need to run CS5Clean. I've done this and while I have some software installed (Flash Builder, , I've never installed Premiere before. Here is the output of my cleanup.xml:

(PS5) Required Components are Disabled ? Who can help me?(install problem)

I try to download 3 time PS5 for trial, but i can't select programlist on checkbox.
and I try to download Creative Suit 5 and can't select ADOBE PHOTOSHOP CS5
for install too.
My OS Windows XP SP3 32Bit.
Disk space 9GB
Pls tell me,How i can to this slove problem?
Thank you for every asnwer.

Not sure why this is happening but can be couple of reasons:
1) Your download is not proper , while installing it is trying to find some required components which are not there and showing that they are disabled.
2) Which language have you selected for install.
There must be logs created kept at this location: Program Files/Common Files/Adobe/Installers by the name of Adobe Photoshop CS5. Can you please share that.

Error: JavaFX runtime components are missing, and are required to run this

I tried to build the application using javafx ant build, generated jar file. But when I run the jar file, issue:
Error: JavaFX runtime components are missing, and are required to run this application.
The javafx-class-path: libs/h2.jar libs/jfxrt.jar libs/log4j.jar
Running the JAR file using:
java -jar app.jar
What could it be?

Which version of iTunes?
When you go to Programs control panel you can see as well as uninstall the current version.
I always uninstall Bonjour, MobileMe etc and itunes will ask if I want to reinstall those (no thanks).
itunes and many apps keep an installer cache so they can do a repair-reinstall without a full install again.
I'd install Microsoft Security Essentials 2.0 which is free and excellent.
Programs don't affect data. But if you don't have backups, you are likely past due.
If you have any doubts about the integrity of your system, if you have had to do a hard power down and likely do have issues, you should / could / might want to do chkdsk on your hard drive (hard drive properties tools scan for errors).

JSF design view - visual components are shrinking

Hello,
I have some strange issue while using Design view for JSF and data binding.
Once I drop any data control elements into visual component (panel, etc) my visual components are shrinking to such size, that I cannot distinguish any elements within design view. I cannot use design view since then and have to place all elements base on structure panel.
How to reproduce:
1. Create new JSF page with wizard and accept defaults.
2. Drop one of the panels (panel box, panel group layout) into JSF layout
At this stage my visual elements occupy 100% of design view screen and represent anticipated outcome
3. Drag and drop one of the data control elements (data control panel) into created panels on JSF and create table or form
Immediately after it visual panel where data control was dropped shrinks to approximately 1/4 of the screen and I cannot see neither available space nor created table for my data components.
I figured out, that if I remove created by wizard default <af:messages> tag from the top of my JSF, then design view representation fixes. Not sure if I should remove <af:messages> from all my pages.
Above all looks to me as and bug.
Environment:
-Jdeveloper 11g
-Windows Vista 64b
-Not bundled JDK 6

Hi Shay,
Thank you for response.
1. I tried to play with screen size without result
2. I checked your video post, but this does not resolve my issue
3. This issue occures with all JSF pages and can be reproduced even when following official Oracle step by step tutorials.
4. I figured out, that removing <af:messages> tag resolves the issue ?! It seems this tag is added by default during drag and drop binding.
5. On this link http://drop.io/jdev_001 you can see how design view is changes with and without <af:messages> tag
6. Below is code example from one of the tutorials, that leads to shrinking as well:
7. Once app is deployed and running page get normal view in IE as expected, so it seems to me, it is issue with Jdev design view, probably influenced by my environment, if nobody reported it before.
Thank you for your help.

Setting ToolTips for items which are disabled.

Folks,
No offence meant if this is a repeat.
I have a JPopupMenu with Action as its components.
1) I have disabled certain menu items to false.
2) I would like to use a ToolTipText to show a message 'You have no permission'
when the user hovers over the menu items which are disabled/set to false
3) I wrote my own ToolTipText,but what is happening is that I am getting the tool tip text
for all menu items.
Please can anyone help me in how to get tooltiptext for menu items which are enabled to false?
Help much appreciated
// JPopupMenu
JPopupMenu pm = new JPopupMenu();
// Add Action
pm.add(new GraphAction());
pm.add(new DescendantsAction());
pm.add(new DebugAction()).setEnabled(false);
ToolTipTextForMenuItems.setToolTipForIndividualItem(pm.getComponent()) // Does not display any Tool Tip.
pm.add(new ResetAction()).setEnabled(false);
ToolTipTextForMenuItems.setToolTipTextForMenuItem(pm); // Shows ToolTipText for all menu items (disabled and enabled)
ToolTip Code
public class ToolTipTextForMenuItems {
private static final String TOOL_TIP_TEXT = "You have no permission";
     public static void setToolTipTextForMenuItem(JPopupMenu popupMenu){
             for (int i=0; i<popupMenu.getComponentCount(); i++){
                Component c = popupMenu.getComponent(i);
                if (c instanceof JComponent) {
                          ((JComponent)c).setToolTipText(TOOL_TIP_TEXT);
     public static void setToolTipForIndividualItem(Component c){
           if (c instanceof JComponent) {
                     ((JComponent)c).setToolTipText(TOOL_TIP_TEXT);
}

Yes,I have looked at the Abstract Action code sent in
I have not used Action and Abstract Action before,hence if you can/could just
modify this as per my requirement,then I can enhance on this.
No offence meant for the above
Thanks

After updating to Firefox 7.0.1, menu bar for Google,yahoo, Facebook (message,notification,profile,home) and others site are disabled. How can solve this problem?

after updating to Firefox 7.0.1, menu bar for Google(web ,image,video,map etc),yahoo, Facebook (message,notification,profile,home) and others site are disabled. even I cant log out from different sites cz the log out bar is completely disabled. I tried with Firefox 4;5 and 6, same problem exist . I tried by active all add ons for facebook, same problem exist. If I use internet explorer , I don't find such problem with it.
How can I solve this problem?

Thanks a lot for your swift response. And sorry if it was a bit too hectic to go through my detailed query (which I did because it was misunderstood when I asked previously). As I've mentioned above, I was informed that updating to 5.0.1 would '''require''' me to '''delete''' the current version and then install the new one. And doing so will involve losing all my bookmarks. I guess I should have been more specific and detailed there. By losing, I didn't mean losing them forever. I'm aware that they're secured in some place and deleting and installing the software doesn't harm its existence. What I meant that if I install the new version, I'd have to delete the old one. And after installing the new version, I'd have to transfer them (bookmarks) back from wherever they are. Get it? When it updated from 3.6.9 to 3.6.13, and from 3.6.13 to 3.6.18, I didn't need to follow that process. They were already present on their own.
BTW, I'm having no problems with 3.6.18 but after learning about the existence of version 5.0.1, I'm a bit too eager to lay my hands over it.
Thanks for your help; hope this wasn't extremely long.

AE CS6 won't export MP4. "Some of the required components could not be found."

After Effects CS6 (from Production Premium) running on 64-bit Windows 7 Enterprise SP1.
Processor: Intel Core i7-3930K CPU @ 3.20GHz
AMD Radeon HD 7900 Series video card
64 Gb Corsair Ram (DDR3)
Quicktime 7.7.4 Installed
Currently attempting to export a short (2 second) video based on the predefined "H.264" preset with the only alterations being that I want the VBR 1 Pass to target 3.5Mbs (though I've changed this with no difference in outcome) and I want the video to multiplex as MP4. I immediatley get the error prompt: "Some of the required components could not be found."
*Just tried using the 3GPP multiplexer and received the same error message. If I try to use the MPEG4 format I get an "unknown exception" error.*
I've exported literally hundreds of items as H.264 with a MP4 multiplexer on this machine with current hardware and software. And now...no dice. After Effects boots correctly (or at least it seems that way) though I think it takes a little longer than it used to (not sure if the system cache just needs to be rebuilt).
After Effects CS6 has all available Adobe updates. Quicktime 7.7.4 is also up-to-date. Video Card driver is up-to-date.
What could be going on? I'd prefer to skip re-installing this program. I've had to do this numerous times already with this suite throughout the past 12 months; really getting sick of the down-time during reinstall. Worth noting that I have closed the program, closed all programs, restarted computer multiple times.
I am currently going through my Adobe program files for After Effects. I am specifically looking through the 'Support Files' directory. A couple interesting things: 1. My 'MediaIO->Codecs' directory was last updated on 11/8/2013 (perhaps an AE update??) but each of the files within said directory have a last modified date of late September. Did something get wrongfully deleted in the hypothetical update? 2. In 'Media Core plugins->Common' I again have a last modified date of 11/8/2013, but again each of my files within the common directory were last modified late September. I have many expected .prm files but NO ImporterMPEG4.prm; should I have a MPEG4 specific importer file, or does the MPEG importer file do all of the work. Also, I have no ExporterMP4 (or anything of the MPEG, MPEG2, MPEG4 flavor). Should I have one of these?
Don't know if this last paragraph helps at all but my fingers are crossed.

Thanks Katrina for all your help.
I talked to an Apple tech support person. Actually, my call had to be elevated to the next support level. Joy. You are correct, there are multiple listings of the files in the error report even though there is only one copy.
The support person had me do a few things. Here is what eventually seems to fix things:
1) For the mp3's that DID copy but were listed as not found... Some files were duplicated so deleting the duplicate with the "!" was an easy fix. I found one file that I could search by song name in iTunes but could not find it by song name search on the iPod. Looking at the iPod playlist I found the file listed by the filename (not song name) and the file played fine. Then in iTunes I double clicked on the song name ("!" showing) and selected locate. I then pointed to the location on the NAS. Resync and now the name of the song on the iPod changed from filename to song name. The file was no longer listed in the error report.
2) For the m4a files that didn't sync... the problem songs appeared three times in a search in iTunes. Two of the listings showed the "!" next to the name. I deleted these two for each song that didn't sync and all transferred fine afterward.
Perhaps there is an issue with ID3 tags since I use filenames more than tags in organization. Still, I would think that iTunes would not get so confused or be a little more friendly with its errors, especially considering how long its been around.
Thanks again for your help. Looks like I have a manual way to correct this issue.

That's crazy. A serial number is not required.
Are you certain you chose the correct version to download?

Follow these instructions to completely remove Apple software

download iTunes again from Apple.

If you have 64bit Vista or Windows 7, look for the seperate download of iTunes for that further down the page.
Once installed, use the Apple Software Update under your Start Menu to fully update all Apple components.
Your content will remain on the drive in the Music > iTunes Folder, nothing is deleted.
You should be making backups of your content regularly, either through iTunes or via copying the iTunesFolder in your Music folder to a external drive.
Windows is notorious for having "other" issues that make it unstable, we as volunteers helping others can't always resolve those issues.

ITunes (11.3 64bit) cannot run because some its required files are missing. Please reinstall iTunes.

just set up my new laptop lenovo x240.
Windows 7 SP1.
itunes 64bit 11.3
first install went fine. then I tried to move my preexisting library. the library did not show the apps. so I tried around. Treid to re-install itunes.
Since I did, after the re-install, iTunes gives me the error message "iTunes cannot run because some its required files are missing. Please reinstall iTunes."
I tried the -_> link: Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
unfortunately it did not resolve. please, advise... I am quite desperate... and surprised this is happening, since I am on a clean corporate laptop.
perhaps, can someone also steer me to a corner, where I can deactivate the cloud install pop-up ones starting iTunes?

See the advice given in the user tip:Troubleshooting issues with iTunes for Windows updates for a very workable approach.

ITunes cannot run because some of its required filles are missing

When I started iTunes I get an error message that says "iTunes cannot run because some of its required filles are missing.

Now I have no itunes...

Hello Melly89,
Thank you for using Apple Support Communities!
It sounds like we need to uninstall not just iTunes, but its associated softwares as well.
I recommend this article to help with accomplishing this task:
