64 bit version of Lightroom 4.1RC2

Is there a 64 bit version of Lightroom 4.1RC2. Looks like I have a 32 bit version running on my 64 bit OS (Vista 64 Ultimate)? It certainly looks like that if I look at the system info in the Lightroom Help menu. Only 4 GB seen, 1228,8MB available for Lightroom?

If it's installed on a 64-bit OS, it's the 64-bit version.

Windows 8 Upgrade - 64-bit version of Lightroom -application error 0xc000007b

I've just upgraded my Desktop PC from the 64-bit Windows 7 operating system to 64 bit Windows 8 Pro. The migration has gone very smoothly, with justone exception - Adobe Lightroom 64-bit version 4.2 won't start up. As soon as I try to open the application it comes up with an error code of 0xc000007b.
Searching the web I've seen a number of suggestions which I've tried to to avail...
- uninstal, restart and then reinstall Lightroom. Same 0xc000007b error
- uninstal, restart, run ccleaner to clear registry issues, restart, download the latest version of Lightroom from Adobe website (4.2.1) and then reinstall Lightroom. Same 0xc000007b error
As a workaround I found that uninstalling Lightroom 64-bit and reinstalling the 32-bit version (by selecting the setup32.exe program, rather than using the install Lightroom 4.exe program) gives me a working copy of Lightroom again. This does however mean I'm using the the 32-bit version of Lightroom, rather than 64-bit version that I had working before the upgrade to Windows 8.
Why am I getting the 0xc00000fb problems with the 64-bit 4.2.1 version of Lightroom and how can I resolve the issue so I can go back to the 64-bit version that I had working in Windows 7 immediately before upgrading to Windows 8?
Thanks for suggestions!

I have a 64 bit version of Lightroom. Where or how can I obtain a 32 bit verson for my 32 bit laptop

I have a 64 bit version of Lightroom. Where or how can I obtain a 32 bit verson for my 32 bit laptop?

The download contains both versions and the same registration key will activate both of them.

How to download the 32 bit version of Lightroom 3.3, with a Windows 7 operating system?

When I originally downloaded my version of lightroom, it was on my older computer- and the 32 bit was downloaded. Have not had any problems with it. When I re-downloaded lightroom onto my newer computer, it automatically downloaded the 64 bit version (because the new computer is Windows 7)... I didn't think any thing of it until I attempted to burn a disc and was unable to- so, it's basically useless to me.
So- I was told to uninstall the program and re-install (typing in same serial number) and to be sure to choose 32 bit this time... but i've done that and now realize that it doesn't even give me the option- just automatically downloads the 64 bit, so not sure what I am supposed to do now? I had no idea that there would be issues with newer windows operating systems!
Any advice????

And just to be totally clear, the only 'issue' with the 64bit version of LR3 was the lack of a dedicated "Burn to Jpeg" Export Preset, caused in turn by the lack of an appropriate 64-bit driver.....however, it was/is still easy enough to export to a CD/DVD using LR3 64-bit, simply by selecting the DVD drive in the Export Location field in the export dialog.
So no need to upgrade from LR3 to LR4 just to be able to burn a DVD (plenty of better reasons than that for upgrading), and also no need to downgrade LR3 from 64 bit version to 32 bit version either.

How can I install the 32-bit version of Lightroom 4.4 on my 64-bit Windows 7 system?

I need to install the 32-bit version of LR 4.4 on my 64-bit Windows 7 system because, for some reason, LR 64-bit is not compatible with something in my computer system.
How can I make this happen?
Thanks,
Mary

The first stage of the installation process for a download is to extract all the installation files into an "Adobe" folder. Go find that folder and look inside, and down at the bottom level of the folder hierarchy are two files: Setup32.exe and Setup64.exe. So uninstall the 64bit version and double-click on "Setup32.exe" to install the 32 bit version.
BTW, what problems are you having with the 64 bit version?

Install 64 bit version with same license

I installed the 32 bit version of Lightroom on my 64 bit computer that is running Windows 7 32 bit. I'm going to upgrade the OS to Windows 7 64 bit...can I install the 64 bit version of lightroom without paying for a new license?

Yes. Just use the same serial number.

Due to our operating system we only have 32 bit, purchased lightroom 6 and download cancelled as says needs 64 bit, is there a 32 bit version i can get, otherwise need money back

thanks for that, but having tried the various options, still not managed to organize a refund, or anything for that matter, been on hold now for 25 minutes, first time was for 17 minutes, spoke to someone who was putting me thorough, to then have automated message saying issue could not be dealt with and it then hung up! been on to live chat and this was posted: -

Which would be funny if i havent already spent 3 1/2 hours trying to sort this. I am really not enjoying my adobe experience, never known such a difficult company to speak to a 'live' person. Now on hold for 29 minutes and need to go out so nothing to be done now until tomorrow. If there is a real person from Adobe reading this, i would appreciate a call/direct email to get this resolved. now 31 minutes and I have to hang up as need to go!!! aarrgghhh!!!

Using vista 64 bit with current versions of lightroom and CS3

Since the new versions of lightroom and photoshop are going to run on 64 bit I was thinking of upgrading to vista 64 bit. Will the present versions of lightroom and CS3 function in the vista 64 bit environment
thanks
Roger Lieberman

I use both LR & CS3 on both XP 64 and Vist 64. They wor just fine. In fact you get access to more RAM. Research your printer drivers etc though. That's an issue.

I did some googling and found alot of topics from you on this issue, to me it simply seems like on of the connectors is broken or loose.

Does lightroom wok on a Windows 7 64 bit version ?

I would like to know if LR is compatible with Win7 64 bit version (which would enable me to take advantage of the 6Gb of RAM of my computer, which is only partly supported by the present 32 bit version.

Both programs will work with Windows 7 Service Pack 1 64 bit version.

I have two versions of Lightroom installed on my computer, can I uninstall the older version?

While looking at the "Programs and Features" folder on my Windows 7 computer I discovered that I have two versions of Adobe Lightroom installed on my system. One is Lightroom 5.2, installed on 9/19/2013, and the other is Adobe Photoshop Lightroom 5.5 64-bit, installed on 7/5/2014
- Can I uninstall the older version?
- Will uninstalling the older version cause any problems with the newer version?
- If yes to either question, is there anything I need to do before doing the uninstall (i.e. deactivating, etc.)
Any advice on how to correct this problem is gratefully appreciated.
PS; I have the same issue with Muse CC. See: I have two versions of Muse CC installed on my computer, can I uninstall the older version?

Jim,
I thought it was odd that I had two versions of Lightroom installed as well. I have been able to track the issue back to an apparent "bug" in the Lightroom 5.2 update that installed a second version of Lightroom in addition to updating the existing version on my computers. At the time, I posted about it at Lightroom 5 installed twice on my laptop. While I never got an answer to my question, which was "Is this normal?" I did hear from others in the forum the experienced the same problem and had the same question. As time passed, later releases updated one of the two installations, but did not effect the second. Hence, two different versions of Lightroom 5 installed on the same computer.
Uninstalling the older version solved the problem. Thanks

64-bit version of Photoshop Elements & Premier Elements 13

Yesterday I purchased Adobe Photoshop Elements and Premier Elements 13 at an Office Depot Store. I was finally able to download and install the Premier Elements. The Photoshop Elements 13 will download, but it will not install. Near the end of the 35-minute installation (which I have done 8 times) I get a message saying it will not install and that I need the 64-bit version. There was not an option for the 32 or 64 bit versions when I made the download. How can I get the 64-bit version without paying for the product again?

I installed a 32 bit instead of the 64 bit version of the photoshop premiere product, it currently will not open, what should i do?

should I uninstall the 32 bit version?

normally both versions will install on a 64 bit system (and both should work).
make sure there's no antivirus/antimalware program interfering with startup and, if needed, uninstall and reinstall,
