Mac - PDFs won't open in Safari

my employer uses system uses online pdf forms.  it's not working on system.  running macos 10.6.4, safari 5.0.1 (6533.17.8), , adobe reader 9.3.4.  have removed adobe reader app, including plugin in /library/internet plug-ins, , re-installed reader.  when click on pdf in browser, downloads, , not open in browser.  how can resolved?

in snow leopard, safari 64-bit application.  adobe hasn't updated plugin run in 64-bit mode; that's why it's not loading in safari.

 

but can force safari run in 32-mode, , adobe plugin works expected.

 

here's how:

 

to this,

 

1. in finder go applications folder, select safari , file->get info
2. check 'open in 32-bit mode' in general pane of dialog, close "safari info" window.
3. relaunch safari

now acrobat plugin work expected.

there 1 downside this: when running in 64-bit mode, if buggy plugin (like flash) crashes, safari keeps running.  in 32-bit mode, if buggy plugin causes crash, safari crash.

the real fix adobe update plugin run in 64-bit mode, since snow leopard has been out on year already!
