Install 32 bit or 64 bit version of Windows?

I plan to install Windows using Parallels. I have a MacBook Pro i5 Intel processor. I haven't purchased Windows yet and noticed it comes in 32 bit and 64 bit versions. I tried reading up on the difference and I sort of understand what they are saying, but wanted to know which one is more compatible with a Mac? My computer is about a year and a half old. I probably will use it mostly to play games that are PC only, and also to test out the websites I develop to see how they look in a Windows environment on IE. Would appreciate any suggestions.

i would go with 64 bit. With the larger instruction size, you will see a noticable improvement in speed and performance. Since macs are built with 64-bit processors, this will not be an issue.

Why does Bootcamp install 32-bit version of Windows 7?

I am trying to install Windows 7 Ultimate (64-bit) via Bootcamp on my mid-2011 Mac Mini Server. The Windows install succeeds but I am unable to install the Windows support files. When I try to run the Setup program in the Bootcamp directory, Windows won't run the file and says that the file is incompatible with the OS.
It turns out that Windows 7 is reporting that it's a 32-bit OS and, apparently, the Bootcamp support files are for the 64-bit version of the OS.
Where have I gone wrong?
Thanks,
JZ

This is a case of me being ...well let's say 'inattentive.' The Windows disk I was using for the install was indeed 32-bit. I forgot that I have 64-bit and 32-bit versions of Windows 7 and I installed the incorrect version.
Thanks for the reply, Rudegar.

HT1846 ok, so now what? how to uninstall 64 and then install 32 bit version of Windows 7 in bootcamp?

please help. i just wasted a couple hours installing and then updating the 64 bit version.

There is today no reason to be using 32-bit
And it isn't rocket science to just reinstall and format like you did before from the DVD
But I have not seen where 32-bit version was needed and that programs and drivers were an issue.
Assume you know how to use Boot Camp Assistant and read the help guide inside.

Unable to install 32 bit version of Office 2013

We had several computers deployed with the 64 bit version of Office 2013. Due to some unforeseen compatibility issues, we needed to remove the 64 bit version and then install the 32 bit version. While we have been able to remove the 64 bit version,
we are not able to install the 32 bit version. After we click setup.exe, We simply see the Office 2013 splash page that mentions "Please wait while setup prepares the necessary files" and then it disappears. Nothing in the event log either.
Any idea what is going on and how to resolve this?

Hi,
Do you mind telling us which category of Event viewer have you checked?
Most of the setup error log may be stored in Setup category, and some in Application category.
If there are some error logs, please upload, they'll help us to troubleshoot this issue.
Then, this issue also may be due to the remain of Office 2013 64bit. I recommend we remove it manually and clean the registry key:
==========
Method 1
Open C:\Program Files\Microsoft Office 15\root\integration\
Delete all C2RManifest*.xml files in that folder.
Open an elevated command prompt. Tap on Windows, enter cmd, right-click on the result and select run as administrator from the menu.
Type cd "C:\Program files\Microsoft Office 15\root\integration".
Type integrator.exe /U.
To remove the Office 2013 preview scheduled tasks run the following commands.
Type schtasks.exe /delete /tn "FF_INTEGRATEDstreamSchedule"
Type schtasks.exe /delete /tn "FF_INTEGRATEDUPDATEDETECTION"
Type schtasks.exe /delete /tn "FF_INTEGRATEDOffice 15 Subscription Heartbeat"
Keep the command prompt open.
Open the Task Manager with Ctrl-Shift-Esc.
Click on the Process tab and kill the following processes: integratedoffice.exe,
appvshnotify.exe, firstrun.exe and setup*.exe.
Type sc delete OfficeSvc at the command prompt.
Open Windows Explorer and delete the Microsoft Office 15 folder

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppVISV
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft Office 15 - ProfessionalRetail - en-us
Note that the name of the last Registry key depends on the installed version of Office.
Delete Office 2013 start menu shortcuts
Open %ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs and delete the Office 2013 folder
Go to the command prompt and run one of the following commands:
If you are running an x86 version of Office 2013 and an x64 operating system run the following command:
MsiExec.exe /X{50150000-008F-0000-1000-0000000FF1CE}
If you are running an x86 version of Office 2013 and an x86 operating system run the following command:
MsiExec.exe /X{50150000-007E-0000-0000-0000000FF1CE}
If you are running an x64 version of Office 2013 and and x64 operating system run the following command:
MsiExec.exe /X{50150000-008C-0000-1000-0000000FF1CE}
Run the following command afterwards: MsiExec.exe /X{00150000-008C-0000-0000-0000000FF1CE}
Method 2
Open the %windir%\Installer folder. Make sure you can view Hidden files and folders on your system
Select View, then Choose Details

With Boot Camp, should I install the 64 bit version of Windows 7 (Home Premium edition) OR the 32 bit version when installing onto an early 2008 Mac Pro operating OSX Lion with a 1 TByte internal HDD?

With an early 2008 Mac Pro I'm about to add a second internal drive (1 TByte SATA) and initially install OSX Lion onto the new drive. Then to partition this new HDD via Boot camp. But my question is whether I am best advised to purchase the 64 bit version of Windows 7 (Home Premium) or the 32 bit version of Windows 7 (Home Premium) for the Windows sector of the disk What are the differences, and will I notice a difference in performance?

In chart from wiki, (scroll down to "Comparison chart") check the maximum CPUs supported.
You don't see this on MSoft's 1st searched for chart hit. This is one reason you will regret not paying for Professional+ if you get Home Premium 64 as I did for Mac Pro early 2008.
Home Prem Task Mgr sees 4 processors vs. the 8 that are seen by Pro+.
Costs more than a Mac upgrade to Lion if you make that mistake.

Itunes is not recognising my ipod!! says i need to install 64 bit version, it is 64 bit version though!!

itunes is not recognising my ipod!! says i need to install 64 bit version, it is 64 bit version though!!

Let's try a standalone Apple Mobile Device Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of why it's not installing under normal conditions.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleMobileDeviceSupport.msi (or AppleMobileDeviceSupport64.msi) to do a standalone AMDS install.
(If it offers you the choice to remove or repair, choose "Remove", and if the uninstall goes through successfully, see if you can reinstall by doubleclicking the AppleMobileDeviceSupport.msi again.)
Does it install (or uninstall and then reinstall) properly for you? If so, can you get a normal iTunes install to go through properly now?
If instead you get an error message during the install (or uninstall), let us know what it says. (Precise text, please.)

i keep installing itnes on my laptop same version of windows as my other laptop and this one keeps telling me to install 64 bit version and i have downloaded that version already and installed it several times but does not connect to ipod

That message usually indicates that Apple Mobile Device Support hasn't installed correctly.

Yes, it's come up a number of times. If you look to the right under "more like this", you'll find threads that may offer useful suggestions.

Doublechecking. What's the filename of the installer you've been downloading? (The 32-bit installer is called iTunesSetup.exe, and the 64-bit installer is called iTunes64Setup.exe.)

How to stop auto installing 32 bit versions?

I noticed that CC ist istalling both versions - 32 and 64 bit without asking me if I need it. So I've got now every programm in two versions but I only need 64bit and this also wastes many space on the hd ... this is critical because my hd is really small. Is there a way to tell CC and the updater to only install 64 bit versions?

Mylenium's response is correct it is not possible to customize the installation package through the Creative Cloud Desktop application at this time. Also please be aware that depending on the software package not all functions or third-party plug-ins maybe functional in a 64-bit environment.

ITunes 7.6 and Windows XP Pro x64 ---- 64 bit version of Windows XP Pro

My wife was given an iPod nano, so I downloaded the current version of iTunesSetup.exe from www.apple.com and tried to run the executable. It told me that it wasn't designed to install iTunes on my 64 bit version of Windows XP Pro, and that I should go back to www.apple.com and download the 64 bit installer. I went back to www.apple.com and searched for the 64 bit installer in vain. There is only one main link to the current installer and the website determines which version of the installer you're given. After a few google searches I managed to aquire iTunes64setup.exe from the Apple site. I ran the executable and it told me "This iTunes installer requires that your computer is running Windows Vista 64-bit" and then it gave me the option to exit. I ended up installing iTunes from the executable I had originally downloaded. I have iTunes 7.6.2.9 installed now but it doesn't detect, or can't operate my DVD burner, so I can't rip music with iTunes for use on my wife's nano. I get this error report when I run the Diagnostic test built into iTunes.

And there was no change in the diagnostic when I first tried to repair the install and then tried to reinstall iTunes. I'm sure the burner is working because I can play music, watch movies and all the normal stuff a DVD burner can do using Nero.
I'm guessing I need an iTunes version of 64 bit optical drive driver.
Any help would be appreciated!

I got the iTunes 7 to work on XP Pro 64bit. What I did was this:
1. Downloaded DriverInstaller_AMD64EM64T.exe
2. Installed it.
3. Created this file tree: C:\Windows\Sysnative\drivers (Easier terminology, I went into the Windows folder and created a folder named "sysnative", opened that folder and created another folder called "drivers".
4. Then I located the folder where I installed DriverInstaller_AMD64EM64T.exe ..
5. I took the file called GEARAspiWDM and COPIED IT. I DID NOT MOVE THIS FILE!!!
6. I pasted a COPY of this file into sysnative\drivers. The folder I just made.
7. I installed iTunes 7, not 7.6. 7.6 and this method won't solve the burning issue. That would require more programs and more patients.
Note, you will have to manipulate iTunes when you want to burn. The best way to do this, I found, was to simply make a playlist and right click the playlist on the left column and select burn to disk. It should act normally.

How to use Internet Explorer 11 64 bits rather than the 32 bit version, on Windows 7 familial premium 64 bit

Hi,
my system : up to date computer, W7 familial premium (64 bit), Internet Explorer 11 (32 bit)
I use this computer on the web to visit just one website, always the same and several hours a day ; this site advocate the use of Internet Explorer 64 bits for more efficiency.
How can I get to install, or switch to the 64 bit version of Internet Explorer, as presently when I try to install a downloaded version, I get as an answer something like "installation not possible because the more up to date version of Internet Explorer
is already installed on your computer". Thanks

Hi,
On a 64-bit version of Windows, please click system drive, there should be a “Program Files” and “program Files x86”,
the "Program Files" folder is for 64-bit programs and the "Program Files (x86)" folder is for 32-bit programs, you will find IE11 64 bit has already installed in you system in “Program Files”>”Internet explorer”.

Why is there no Boot Camp support for the 64-bit version of Windows 7 on the 64-bit iMac that I'm using?

The early 2008 24" iMac 8,1 has a 2.8 ghz E8235 Intel Core 2 Duo processor with a data width of 64-bits.
I am straining badly to understand why Apple is only providing drivers for the 32-bit version of Windows 7 for the 64-bit hardware that I want to install it on.

The 64 bit drivers are there, but there have been some installation
issues depending on Windows OS and Apple hardware. You may
want to post on the Bootcamp forum to get more direct response to
your issue.
FWIW, at one point, I forget when, I found I needed to manually
open the 64 bit versions of the drivers to install them that were created
on the bootcamp driver install disk (image). As I recall the was a
64 bit .msi "global" installer but even at that there was an individual
one that needed to be manually installed.
Its been a while since I last did this since I have been doing everything
in Windows virtual machines with Parallels.

What/Where is the 32-bit version of Windows System Image Manager?

I'm running into the problem described as follows in the WAIK documentation: "Windows SIM fails to create a catalog for a 32-bit Windows image from a 64-bit version of Windows SIM. To workaround this issue, use the 32-bit version of Windows SIM to
create catalogs for your Windows images."
Question: Where is the 32-bit version of Windows SIM? I can only find a single download for "The Windows® Automated Installation Kit (AIK) for Windows® 7"
Or are the 32-bit tools included in that version? If so, how do I use those instead?

Hi,
The issue should occurs when you install the WAIK on a 64bit Windows 7 machine.
You need install WAIK on a 32bit machine.
Different binary versions of Windows SIM cannot create catalog files for some Windows images of different architecture types. We recommend using the
32-bit version of Windows SIM to create catalog files because this version can create catalogs for all Windows image architecture types. The following list describes the Windows SIM architecture types and catalogs that can be created for each Windows
image architecture type.
x86 Image Manager. Can
create catalogs for x86, x64, and Itanium-based Windows images.
x64 Image Manager. Can
create catalogs only for x64 Windows images.
Itanium-based Image Manager.
Can create catalogs only for Itanium-based Windows images.
