cs 5.1 and 32 bit exr files

[rogue3d]

So we bought two copies of cs5 extended. at work I can open exr files and edit them in 32 bit mode. when I installed at home I can't. same version just that at home when I open them, all the options are greyed out and all I can do is set exposure and switch to 16bit mode. seems odd that this works on one machine and not another.

 

I tried the exr alpha, that didn't seem to help. The only real difference is that at the office it was clean install on a new drive and at home I have cs3 previously installed. uninstalled cs3, reinstalled cs5.1 and nothing.

 

Any ideas?
