An Error Occurred When Attempting to Change Modules – Adobe Lightroom OSX 10.5 Leopard Compatability
St. Louis Wedding Photography Blog Add commentsI shot a wedding this weekend for a family friend and at the reception, I met one of the bride’s uncles who has a very impressive collection of camera equipment. We talked about workflow and processing photos and he mentioned that he uses Adobe Lightroom to process all of his photos before exporting them to Photoshop.
I downloaded the updated demo of Lightroom and after installation, I was immediately presented with the error, "An Error Occurred When Attempting to Change Modules." I was a little frustrated thinking it was an issue with my machine and honestly there was not much information on Adobe’s help section. Finally I found the answer when I looked at Adobe Lightroom’s system requirements…. It works on Apple OSX 10.4 but it does not list compatibility for Leopard (OSX 10.5).
View Lightroom on Adobe’s site but be sure to read the system requirements before purchasing – I suggest using the demo to make sure it will work. If you are on Leopard, good luck!

I’m running 10.4.11 on a 2.4 Ghz Intel Core 2 Duo with 2 GB of Ram. I’m getting the same message. After a lot of troubles I have only just managed to get Lightroom to run on my iBook G4. Have no idea how to make it run on my Intel Machine. Other people have had no problems. I did manage to get it working on my PC.

I have still not been able to get Lightroom working. What astounds me is that Adobe is really not that helpful in addressing this. Obviously this isn’t an isolated issue and it seems that it is a problem related to a prior installation of Photoshop or the Adobe Creative Suite. I don’t want to take the time to wipe and reload my Macbook Pro just for the chance that Lightroom will actually work.

Everybody who uses the program rages about it. Now I have it working on the iBook with it’s small 13 inch screen I will have to start using “Lightroom” to justify the money I spent on it.
I should have read up more about the program before buying it.
Do you know if “Aperture” has any issues?
By the way, You have some great images on your site>

From what I’ve seen, Lightroom is supposed to be superior to Aperture. I have an iMac at home and I might try to install Lightroom on it to see what happens.
Thanks for the complement on my photos. I have a lot more I need to put up but just have little time to add them.

Hi guys, I’ve had this problem a couple of times. Both times it’s been solved by deleting the user/library/preferences/com.adobe.Lightroom2.plist
Hope that helps.

Hey Ben, thanks for the input. I gave that a shot and had no luck. I’m going to try to install the program on a new user and see what happens. If it works, I’ll try to copy the install files to the main user account.

I figured this out.
You have to delete the adobe lightroom folder in the library/app support and the users/lib/pref/com.adobe files too… then startup lightroom and it’ll be fine.
Good luck backing up though. I guess this is only a fix for new libraries

I have actually attempted that as well and had no luck. Thanks for the suggestion – it may help another user.

I just stumbled upon this blog while looking for an answer to the same problem. I have a friend that’s using LR on Leopard OSX 10.5 with no module problems whatsoever.
Also, I want to try deleting the folders and whatnot, but seriously have no idea how. Can someone give me help in easy and generic terms?

I had this annoying problem too! I noticed that launching Lightroom from a freshly new created account would solve the problem.
I figured out there was something wrong in my main account. In fact, I had an old Lightroom directory (from a previous installation in 2008) that was located in Users//Library/Application Support/Adobe
Deleting this directory solved the issue. It was in fact missing a lot of subdirectories (probably partially deleted, when I removed the program back in 2008), but my new installation was still relying on it. Trashing it allowed Lightroom to create a complete new one, with all subdirectories: Develop Presets, Export Presets, External Editor Presets, Filter Presets etc.
Problem solved

Daniel.. thanks.. i was about to kill myself

After two and a half frustrating hours bouncing back and forth between apple and adobe, who blamed each other, I found success with Daniels (#7) advice. Good luck to others.

Tried the various options shown above. Did not work. Deleted everything and will try again.
What is annoying is that I contacted the site requested by Abode in the Beta video and they responded by asking me which version I was using (Snow Leopard) and that was the end of that. Nothing further. I had to end up on YOUR site to even get an inkling of what to do next. Amazing!

Daniel number 7 is so helpful! Do that guys if your Lightroom is messing you up! I use Leopard 10.5.8, now it is working! Thank you, Daniel! mwah mwah

Daniel is the man. If you follow his advice make sure to delete the files in BOTH libraries. Before I found this thread I had only deleted in my user folder and was frustrated because it didn’t work.
Adobe put the fix on your site WTF?

I just came across this and you all helped me solve this same issue I was having instantly! Thank you!!!!!!!

Hi folks,
Boy am I glad I found this site and this thread. I’m new to Nikon, but not to photography.
I bought a D300, and the MB-D10 battery grip. I’m the kind of user who reads the manual (no matter what it’s for) from cover to cover. I was following along with camera in hand.
I got to the section about showing battery voltages, and how there should be a ‘BP’ icon on the top control panel when the battery grip was attached and had batteries. Only I was never seeing the ‘BP’ icon on top, nor did ‘Battery info’ from the menu show anything other than the internal battery.
I tried several sets of AA batteries, both rechargeable NiMH and disposable Duracell Lithium Ultra; all with the same results.
I read this thread several days ago, and tried the various troubleshooting steps that people outlined. The one thing that kept stumping me was that if I took the internal EN-EL3E battery out of the camera and just attached the battery grip; the camera wouldn’t power on. It displayed a small battery icon on the top control panel that only had the bottom corner filled in. This icon flashed several times.
I called Nikon, and two different people there told me that it was not possible to run the D300 without a battery in the camera, even if that battery was completely drained.
I called Nikon back this evening and spoke to a different person. He again said the camera would not run if there was no battery in the camera; and that either my battery grip or my camera or both were defective and in need of service.
Reading this thread again, suggested to me that sending my camera to Nikon would probably not net me anything other than a repair bill and a week or two without my gear. So I decided to try a closer inspection of the AA sled, the contacts, the bottom of the camera, etc. one last time before sending it in.
I can now definitely report that it IS MOST ASSUREDLY POSSIBLE to run the D300 with no internal battery and just the MB-D10 battery grip, despite 3 different Nikon Tech Support reps telling me that it’s not possible.
For the moment, my battery grip is recognized by the camera, and I can shoot in CH at the full 8 fps. I spent the better part of an hour and a half with a high powered light, a head mounted magnifier, a bottle of non-conducting contact cleaner and several foam-tipped “Q-tips”. I gave the contacts on the battery grip a very good cleaning, along with all the contacts on the bottom of the camera. I did the same thing to the AA battery sled, checking for the ‘sagging plastic’ mentioned by one poster in this thread.
I have to say, I’m more than a little annoyed at Nikon! Does anyone from Nikon read this site? I would very much like to talk to a Nikon manager or person higher up the food chain than their Tech Support phone people.
I’m very thankful that some Google searching turned up this site and this thread. Clearly I am not the only one who is having this issue with the D300 and the MB-D10. Thank you to everyone who posted their experiences and their troubleshooting tips! I’m pretty sure that I do NOT need to send my camera and battery grip in to be serviced at this point. For me, the problem *seems to be* a simple matter of dirty contacts somewhere. At least for now.
For those who are having this same problem, if you haven’t already tried a good contact cleaning on the camera and the battery grip; perhaps this will help your problem as well..?..?
