Sharepoint PDF files are not opening in Browser

Scenario tested sucessfully:
Sharepoint 2010
Adobe Reader XI
Internet Explorer 10

For the server side you can follow the instructions described in this link:

To avoid setting the Browser Handling File to Permissive (this is not recommended for security issues), you can execute this command in PowerShell:

$web=Get-SPWebApplication -Identity <WebApplication>

$web.AllowedInlineDownloadedMimeTypes.Add(“application/pdf”)

$web.Update()

For the client side you have to DISABLE the Add-on “Adobe Acrobat Sharepoint OpenDocuments Component” and ENABLE the “Adobe PDF Reader” in Internet Explorer, in the client machine.

Obs: The add-on Adobe PDF Link Helper doesn’t metter in this case.
