Adobe Reader 9.1 Disable Display PDF in browser

[monticus]

Is there a registry setting I tweek to uncheck the box for Display PDF In Browser?  The only ones I could find grayed out the box but it didn't un check the box.

Unfortunately this is for every user.

HKCU\Software\Adobe\Adobe Acrobat\9.0\Originals\bBrowserIntegration should be 0 (DWORD) for unchecked.  1 for checked, or just delete bBrowserIntegration.

Although not test, but for new users, you can have it defaulted to unchecked by creating this registry key:

HKLM\Software\Adobe\Adobe Acrobat\9.0\Installer\Migrate\_8F96F27E-4B57-411A-A268-632AF06C6929

(Default)  REG_SZ  Software\Adobe\Adobe Acrobat\9.0\Originals

name       REG_SZ  bBrowserIntegration

type          REG_DWORD  4

val            REG_SZ  0

I'm just confirming what anhnguyen7902 posted.

This was tested against Acrobat Reader 9.3.1. I exported all of the registry keys from HKEY_CURRENT_USER\Software\Adobe\ with the "Display PDF in browser" setting enabled and disabled. Below are the only relevant differences when changing this setting from within Acrobat Reader.

With the setting enabled, keys under [HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals] are...

[HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals]

"bHostBasedCM"=dword:00000001
"iPSLevel"=dword:00000000
"sProofingSpace"=hex:55,2e,53,2e,20,57,65,62,20,43,6f,61,74,65,64,20,28,53,57,4f,50,29,20,76,32,00
"bDisplayedSplash"=dword:00000001

With this setting DISABLED, keys under [HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals] are...

[HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals]

"bHostBasedCM"=dword:00000001

"iPSLevel"=dword:00000000

"sProofingSpace"=hex:55,2e,53,2e,20,57,65,62,20,43,6f,61,74,65,64,20,28,53,57,4f,50,29,20,76,32,00

"bDisplayedSplash"=dword:00000001

"bBrowserIntegration"=dword:00000000

The difference being the bBrowserIntegration key being present and set to dword:00000000 when this option is DISABLED, but the key being completely removed when the setting is ENABLED.

While writing this post, I decided to test it against Acrobat Reader v4.2.1. The results were the same.

Hope this helps.
