I'm having the same symptom mentioned in this thread: http://forums.adobe.com/thread/1058075
In the Flickr Publish service configuration dialog, the Authorize button pops up a dialog that explains "Lightroom needs your permission to upload images to Flickr," but when I click that dialog's Authorize button, it appears to do nothing (no browser, no error message, etc.).
I am currently running Windows 8 Pro 64-bit and Lightroom 4.3 64-bit.
Here's a history of this problem.
I was using Windows Vista 64-bit with an updated Lightroom 3 (version 3.6?). I was publishing to Flickr using the built-in Flickr publish plugin. That worked flawlessly for the last year, and I never had a problem.
I then upgraded to Windows 8 Pro 64-bit. Unfortunately, I did not test Lightroom 3 at this point.
I then upgraded to Lightroom 4.3 64-bit.
After these upgrades, I tried to publish two photos to Flickr using my existing Flickr publish configuration. I believe that I got some error the first time, which I did not write down. I wasn't sure that the Flickr publish service would upgade correctly, and I did some searching online.
I'm familiar with the Flickr APIs, and I thought that after the upgrade, I probably needed to re-authorize the plug-in. I went to my Flickr account in my browser and revoked Lightroom's permissions. I may have also clicked "Remove Authorization" in the Flickr publish plugin's settings page. After that, I started hitting the problem described above. When I click the Authorize button, I never get a browser pop up.
I then tried a few things.
- I verified the registry entries had the values described in this thrad: http://forums.adobe.com/message/3121076#3121076
- I removed the old Flickr publish service that had been migrated from Lightroom 3.6.
- I uninstalled Lightroom 3.6.
- I ran the "repair installation" for Lightroom 4.
- I ran lightroom.exe -register as the administrator.
- I ran Lightroom 4 as the administrator.
Between each of those steps, I rebooted the machine. When the machine came back up, I opened Lightroom 4 and clicked the Flickr publish service's "Set up" button. I then when to the plugin manager and reloaded the Flickr plugin. Finally, I clicked "Authorize" in the Flickr plugin's settings. Every time, I get the same behavior. "Not authorized" in the settings dialog changes to "Authorizing..." while it shows me a dialog. I click the Authorize button in that dialog. I briefly see a different message in Flickr publish service settings page (Waiting for response...). Then it changes to "Not Authorized." I never see a browser or an error.
With each experiment, I tried with both IE and Firefox set as my default browser. I get the same behavior with both browsers.
I verified that running "start lightroom://www.flickr.com" from the Windows command prompt opens Lightroom 4.3. Therefore, I believe that the registry settings for the lightroom URL protocol are correct.
I have never used the Facebook publish service in the past, but I cilcked on the set up button for that plugin. When I click Authorize on Facebook, it launches my browser (or opens a new tab) for Facebook. Therefore, it looks like Lightroom plugins are able to launch the browser.
It seems like there's something wrong with the Flickr publish service plug-in itself. I'm not sure how to get any additional diagnostic information from the plugin. I'd be happy to try something else, but at this point, I'm out of ideas for troubleshooting.
I can try switching to Friedl's Flickr plugin, but I'd rather just see the builtin plugin fixed or my current problem diagnosed.
