64 bit is the way forward. In 32 bit only around 4GB of your 12GB memory will be used.
The switch, from 64bit to 32bit, will depend on your licence. I think that in some countries the W7 retail pack includes both. Some however do not. For example, because I have children in full time education, I am eligible for the student discount scheme in Britain (around £60 / $95 for W7 Ultimate and £35 / $55 for Office 2007 Enterprise) - however the W7 disk contains only the 64-bit version
Loads of people on this forum are having dreadful troubles with PRE8. While some may be because they have W7-64 there are just as many with problems on W7-32 as well. I suggest you scan the forums to see what troubles people have had - in some cases Adobe have let them downgrade to PRE7. I run PRE7 on W7-64 with very few problems (but my projects are all SD). Unless PRE8 has some 'must have' features for you, you may be better off with PRE7.

}Hi vorrarit,
sorry I couldn't help you. I tried your code one-to-one on my system and everything worked fine, which means that your configuration is somewhat messy.
BTW I read a little about jce and java 1.4.x (for I have java 1.3.06 and extra jce package), the documentation says, the SUN JCE providers are statically preconfigured, so a Security.addProvider(..) is not necessary. Have a look in the java.security file and check if the sun provider is contained. Are you sure, your runtime version points to the directory where the jce is installed, maybe you had installed other java-versions and the pathes got mixed up?
Good luck,

Games run better under rebooted mpb as windows
I've heard that many or certain games run better, (with more fps) under a windows reboot than natively under mac os x (on a mac intel computer). That this is because mac os x has a tighter limit on the usage of the hardware, in an effort not to burn it out. Has anybody else heard this, Is this true? Thanks.
What account is the service running under? It may be that the service does not have access to the folders it needs, or does not have the right java CLASSPATH set.
Can you try running the service under the exact same account that successfully runs via the command line?

I have had Windows 7 64 bit for the past year and have run Firefox with no problem. It was the most problem free of the three browsers including IE and Chrome.
I have a Vista side where I run my online backup and did so yesterday. Went on Firefox. No Problem.
Today I booted into the Windows 7 side. Seemed to boot up okay. Until I opened Firefox. Suddenly, my whole computer crashed, windows shut down and that bluescreen popped up. I restarted normally. Same thing. I restarted in safe-mode. Couldn't find any problems. Went back to regular mode. Started FF. Boom crash.
Back to safe mode. Did a system restore. Back to regular startup. Didn't help. Attempting to open FF crahed windows.
So back to safe mode. Started Firefox. Crashed the whole computer and same blues screen.
So I uninstalled FF. Reinstalled FF. It still makes Windows crash.
So now I am on IE :PSee below -- the way I asked the question the first time may not be clear. This post was a goof but I can't figure out how to delete it

Hi Drgeert-
The hub may not be broken per se, but Apple has made adjustments to the limits on current that can be drawn from ports.
You probably need a new hub.

I have a MacBook 7,1 which i recently installed a PNY 250 SSD and added some RAM. The laptop was running awesome with OSX 10.6.8, lightning fast.
Then I installed Yosemite. There was a bit of hang during the install, but Yosemite came up no issue when I rebooted. Here is the problem:
Every other time I boot the MacBook it hangs at a grey screen with the prohibitory sign. Verbose reveals a "still waiting for root device" error. Now if I reboot from that hang, it boots fine, but then will hang again the next time. It keeps alternating like this. Any ideas??

when i start firefox, everything starts normal then my homepage (igoogle) starts to load, gets to about 30% and stops. from there i can click on links or bookmark and a new tab will open but no page will load. i can't get anywhere. then when i close firefox it appears to close normally but when i try to reopen firefox i get a message that firefox is still running but not responding and the only way to shut it down is to reboot. when it first occured i was running beta 6 (since it became available, i also used beta 4 & beta 5) i then uninstalled beta 6 and downloaded and installed ver 5 same problem. i then did a system restore to a time before the problem.. no luck. i'm not sure what to try next. IE & chrome both work fine
I'm in exactly the same boat - dead at blue screen, only option is to salvage using target mode.
I don't currently have access to another Mac to do target mode. I was planning to buy a new Mac this fall anyway, though. 2 questions in preparation for that purchase:
1) Is there anything I can do before buying a new Mac to make the salvage process more successful? ie, should I spend the time and money going to the genius bar to have them help me get from totally crippled to partially crippled? (As for expertise, I'm a proficient consumer-grade user, but Apple Support walked me through the safe-boot process, etc.)
2) Is Apple going to provide 10.5 once it is released to people who buy a new Mac in these 6 weeks pre-release?
Thanks for your help,

Adobe PDF Printer not working as print driver; 9.5.5 (pro) with Windows 7, 64 bit
I have installed, repaired, uninstalled and re-installed Acrobat Pro 9.5.5 on a newly formatted SSD with Windows 7, 64 bit on my desktop machine. The program was installed from Acrobat Pro 9.0.0 and updated within the program. I have the program also installed on my laptop, and the Adobe PDF Printer driver is working properly on my laptop.
On my desktop with the newly formatted SSD, the Adobe PDF printer driver is not working. Note that I am using the printer driver, and not any pdf creation techniques within MS Office or other programs.
When I go to the Adobe PDF printing preferences on my desktop, I only get a generic, two tab window open. When I print a file to this printer on my desktop machine, I do not get a window opening that asks where to create the pdf or what to name it, and I never see any files created. In MS Word, the Create PDF option under the Acrobat tab works and opens a dialog to ask the name and location to save, and then opens a PDF Maker progress window and properly creates the file. I can also save a file as an .eps or .ps file and use Distiller to create the pdf. However I cannot get the Adobe PDF printer driver in my Devices and Printers to work properly, although it works just fine on my laptop with the same program (Pro 9.5.5) and same Windows version (7, 64 bit).
Repairing, uninstalling and re-installing does not solve the problem. Acrotray.exe *32 process is running. Any ideas on why this won't run properly on my desktop, but will run on a similarly configured laptop?
On my laptop, I get a full, (7) tabl menu with all the normal options:I found this answer from Deepak Chauhan on another forum, and it solved this problem!
Try this to add Adobe PDF printer manually on Windows 7, and Windows Vista.
If windows 7 is Enterprise or better edition: (Admin rights required)
Start>search for printmanagement.msc and open the print management module
Expand the print server and expand the computer name to see availbale printers, drivers and printer ports.
- from printers ensure there's no Adobe PDF printer, if there is delete it
- go to ports and delete the PDF ports (the ones ending in *.pdf)
- go to drivers and delete the PDF converter.
Take note if any errors occur, but continue with the following steps regardless.
If on windows 7 home edition, just goto start>Devices and Printers and ensure PDF pritner is not listed.
Then open the registry (if any erors deleting these keys happen, see below)
1: go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Printers
delete any adobe PDF printer subkey present
2: go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors
delee the PDF port monitor if present
3: go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers
again delete and pdf printer subkey
If any erros occur, you need to set the owner of the key to the currently logged in admin user, then ensure that user has full control.
Do this by right-click the key and selecting permissions, clicking on advanced, then the owner tab.
Once you've all that has been done, open a command line as administrator.
Copy and pate the following commands in order
1: net stop spooler
2: rundll32.exe setupapi.dll,InstallHinfSection AdobePDFPortMonitor 128 C:\Program Files (x86)\Adobe\Acrobat 9.0\Acrobat\Xtras\AdobePDF\AdobePDF.inf
3: net start spooler
4:rundll32.exe printui.dll,PrintUIEntry /if /b "Adobe PDF" /f "C:\Program Files (x86)\Adobe\Acrobat 9.0\Acrobat\Xtras\AdobePDF\AdobePDF.inf" /r "Documents\*.pdf" /m "Adobe PDF Converter"
That should set back the pdf printer.
This seemed to provide the link that provided the Adobe PDF Settings tab to the Adobe PDF Printing Preferences that was missing! -
Hey everyone,
I've got a SB Extigy which has served me just awesome for years and years now. ?I recently upgraded to a better computer with Windows 7 64 bit, and have found that the driver CD which came with the card will no longer install on this OS. ?Windows will recognize it; the rear stereo out and the headphone out are acti've (both at the same time!) however the volume control knob no longer works, the remote doesn't work (I mainly use it just for volume) but most importantly the MIDI ports don't work. ?I use this computer to make music, so I really need to get the MIDI ports operational or get a new card. ?Since this card has been working so beautifully for so long, I don't want to switch unless I absolutely have to. ?I have tried running the CD install in compatibility mode for XP/2000 but no dice. ?I found [url="http://forums.creative.com/t5/Windows-7/Extigy-Drivers-for-Windows-7/m-p/54202" rel="nofollow">another thread[/url] on here where this guy seemed to get it to work, but didn't really leave instructions as to how. ?He gave[url="http://members.driverguide.com/driver/detail.php?driverid=93720" rel="nofollow"> this link [/url]to download the drivers, but there is no exe in there.... how can I install these drivers without the installerI went to the device manager and tried to do an update driver with the source pointed to these files, but I informs me I currently have the most up to date driver already installed.

Labview 2012 Installer builder issues with Windows 7 64 bit
I have a clients project application program I am working on and am having a lot of trouble getting installed applications to work on Windows 7 properly. The Labview Installer sets the default installation directory to "c:\Program Files\" on Windows Xp and on Windows 7 64bit this defaults to "C:\Program Files (x86). When I install the application on Windows 7 and run it, because Windows 7 64 bit unreasonably protects this directory and every folder under it, if you try to write file to any subdirectory under it (like a reports directory), windows 7 will not let the file write to the directory and the file(s) disappear and you get permission errors. This has been difficult to address. Even logging in as administrator, I have difficulty changing the folder permissions. In addition, when I am in the file write process, if the default directory is coded to come up in the file Open/Save dialog, will not properly
go to and display these protected directories. So thinking that OK, I'll just chage the install directory to something direct to the C: drive and not the Program Files (x86) directory, so I have better control of the folder permissions. Now the Installer build gives errors. It built, but the install fails. Looks like National did not test this for Windows 7 very well. I have run into just about every issue possible with Windows 7 and Labview. Clearly Labview was not very well tested with Windows 7 6 bit. I do not have the Internet toolkit added to the application, only the VISA 5.2 driver. Anyone else having application issues with Labview and Windows 7 and have ideas how to work around this??

BuildErrors.txt 11 KBIt's no NI's fault and has nothing to do with 64 Bit either. It is something MS changed starting with Vista, namely tightening security of the whole system to a similar level as was usual on more professional OSes like Unix 20 years earlier. A user has not rights anymore to write into the location where applications are installed. This is for one reason to protect installed applications from being modified by malicious code.
Instead every application should write its runtime data in one of the user writable loacations such as the user's Documents directory for data files, or in the user's or the machine's configuration directory for configuration settings. For single installations you could always set the directory which your application got installed into to be user writable by changing the rights of that directory afterwards but for applications that get installed on normal user computers this is a VERY hacky and discouraged move. Same about installing your application into the root of your system drive. I think it was an oversight by MS to not protect that directory too from user modifications, but was most likely unavoidable to allow DOS application installations to still work.
LabVIEW has functions to retrieve a whole bunch of those preconfigured and user writeable locations and you really should change your application to make use of those locations, instead of trying to write into the installation directory or installing the application into the root location of the system drive, if you want to be compatible with Windows Vista/7/8.
Windows 7 also requires for a number of actions such as installing programs or drivers so called elevated rights. This means that even if you are logged in as administrator you have to explicitedly provide the admin password again to be able to perform the action. This can be done by starting the program as administrator, when this is available in the right click pop-up menu, and is also sometimes done automatically for applications that Windows determines to need those rights such as setup programs for installations.

Exercising/ Running Marathon with Ipod Classic
Hi there and sorry in advance if this is a tired and already answered question. But I looked and could not find a similar topic.
I run extensively 5 mile a day, even in winters. And workout extensively too, plyometrics, etc. And I am wanting to buy a new ipod. Music is my life and I have a very enormous collection of music.
Here are the questions
1) The max capacity available is with the ipod classic 120 GB. Which is an excellent choice for me. BUT is it a good choice for someone like me who is going to be running around with it and exposing it to jerks and bumps and a lot of movement during play?
2) Is the ipod touch a better option (64GB) if I were to use it extensively while running, gyming etc? I understand that everyone will give the usual stuff about flash based memory Vs hard disc (in case of classic). But is that really the case or are there Ipod classic owners who subject it to a lot of abuse and have never reported problems?
I only ask because the difference in terms of money for Ipod 120 GB classic Vs the new ipod touch 64 GB is quite a lot.
Your help and direction to further articles/ research would really help me. I greatly appreciate you taking the time for reading this and choosing to answer.
Thank youis the obvious answer, but I think that if you are going to be using it for this then the classic is too big a risk to take.
From my experience, hard disks can sometimes take quite a bit of bashing about, but nothing like flash based memory does. It seems very hit and miss, some people manage to get away with it for quite a long time, but if you use a classic for this purpose then there is a big risk of it falling over after a very short amount of time.
Basically, if you can take the financial risk of needing to replace it every six months then go for it if the extra capacity is important, but if a damaged ipod will result in no music at all for a while then it's got to be flash. -
PPro CS4 with Windows 7 (64 bit) slow after upgrading to CS4.2.1
I upgraded to Windows 7 64 bit recently. Before I worked with PPro CS4 (4.2.1) in Windows XP 32 bit and performance was fine. My system is not up to date (Opteron dual core, 4GB, ATI Radeon 3870), but performance was o.k. Since Windows 7 I had problems running HD footage natively (e.g. Sony XDCAM) in the timeline (it simply stops after two three seconds). I also had problems using vob-files (which under XP was very smooth). I reinstalled and figured out, that PPro runs better without upgrading to vers. 4.2.1. So for everyone who is suffering a lack of performance after switching to Windows 7, try this, it might help a little.
I had a somewhat similar experience with the 4.2.1 upgrade with my computer. With my Q6600 running at 3.2 GHz, Vista x64 and with PPro CS4/4.1 update, I ran the PPBM4 benchmark and scored an 83.8. I then installed Win 7 x64, clean install etc… and re-ran the PPBM4 benchmark, with the same 4.1 update and with all system configurations the same as before, my score improved to 68.8, fantastic! I was very impressed with Win 7 x64.
This was short-lived because I updated PPro from 4.1 to 4.2.1, re-ran the PPBM4 benchmark and my score fell to 83.1 seconds, not impressed with the 4.2.1 update as far as this benchmark was concerned. I replaced the Q6600 with a Q9450, also over clocked to 3.2 GHz and with Win 7 x64, ran the PPBM4 benchmark and scored a 68.1; I got back everything I had lost in system speed from the 4.2.1 update plus some.
The Q6600 does not have the SSE4 instruction set while the Q9450 does. Perhaps the 4.2.1 update benefited CPU’s with SSE4 while those CPU’s without it, took a performance hit, just a guess. -

Problem with recovering data from Bit Locker enabled hard disk with bad sectors
Hi,
I have Lenovo T430 laptop with Windows 7 and Bit Locker enabled hard disk. While working I encountered blue screen error multiple times. After some time, the laptop stopped to boot by itself and started showing error 'A disk read write error has occurred.
Press Ctrl+Alt+Del to restart' message. I tried to connect the hard disk to a different PC as a secondary drive and tried to check the disk to recover the data. The 500 GB disk is showing as unallocated space and I am not sure how to recover the
data from the hard disk. Appreciate your help to recover the data from corrupted hard disk.
I used the Lenovo Diagnostics tools available in BIOS and it showed 48 bad sector errors on the hard disk. I also used Windows 7 CD and tried auto repair but it looks like it didn't do anything.
Thanks in advance!Hi SenneVL,
Since there are 48 bad sectors on your hard disk, this means the system can not boot any more, the data might not be restored in a normal way, you'd better turn to data restore company for help.
