Lightroom 3.2 Does Not Recognize CS5 Only CS2

[Brad Smith]

My computer dual boots to either x64 or WinXP, where I manually choose x64 on startup. I am running Lightroom 3.2 and Photoshop CS5 in Windows x64. That is, both LR3 and CS5 are installed in c:\Program Files\Adobe. I also have Adobe CS2 (entire suite, including Photoshop CS2) installed in the c:\Program Files (x86)\Adobe directory. I am trying to understand why Lightroom does not see Photoshop CS5 in, for example, Photo > Edit In > Merge to Panorama in Photoshop. In the same menu, it does show my older Photoshop CS2: Photo > Edit In > Edit in Photoshop CS2. Is there a way to make CS5 show up here? I also note that in LR3 Preferences, External Editing tab, Photoshop CS2 is the first choice (automatic/default) for Edit In. Do I have to delete CS2 to get LR3.2 to recognize CS5?

Thanks!

Reinstalling Photoshop usually cleans this up.

Thank you, Andrew. That did the trick!
