When using a non-English version of Adobe Acrobat Reader X (v10) and Application Manager 8.3 / 8.4, the language is reverting from the local language to English.
Additionally, the text for all menu items is blank.
This does not occur for administrators.
Acrobat Reader X creates a cache folder within the users' temporary application data folder, then attempts to execute these files. As the files are owned by the user, these are blocked by Trusted Ownership.
There are a number of solutions to this issue, choosing which is a matter of security vs manageability.
The most secure solution is to add a signature item for each of these files to the Accessible Items either directly, or via a new Group within Application Manager > Library > Group Management, then adding this group to Accessible Items of the relevant rule.
To capture the files required:
1. Logon as an administrator and launch Acrobat Reader (AcroRd32.exe) then close
2. Copy the files from the following folder to a location accessible from the Application Manager Console:
Windows XP / 2003: %Userprofile%\Local Settings\Application Data\Adobe\Acrobat\10.0\Cache
Windows Vista / 2008 / 7 / 2008R2: %localappdata%\Adobe\Acrobat\10.0\Cache
3. Using the Add Signature Item within the Application Manager Console, browse the location of the copied files, and change the File Types drop-down from Executable Files to All Files, then add each file.
Note: Using this approach may require additional signatures to be added for each language and each version of Acrobat Reader.
A less secure, but easier to manage approach, is to use a Process Rule for Acrobat Reader as follows:
1. Create a new Process Rule and add the following executable in the "Processes" list (you could alternatively use a signature of the process itself if required for added security):
2. Within the Accessible Items for this process rule, add either the Folder, or each individual Files within this folder, with Trusted Ownership disabled, or signature items as above. For example on a German OS (for the least secure but simplest approach):
One final option, if security is of the highest priority, is to combine the aspects of both of the above, by using a Process Rule where a Signature Item is used within the Processes List, and the signatures for each of the cache files within the Accessible Items list (either directly or via a Group Item from the "Group Management" Library)
