Acrobat docs do not open on impersonation

[menaka@adobeforums.com]

Hi All,
I have a C# 2005 application and basically in that application i can open an acrobat file..Acrobat files are in a seperate pc in the network and i have given folder permission to the users who are accessing the folder.when a client machine user logged and if he/she has the permission in that folder then they can open the files through the program.
Problem arised when i try to impersonate a different user in the program.Although i gave the permssions to the acrobat files folder, to the impersonated user, if i try to open an acrobat file through the program it says the below error.

Could not load file or assembly "Interop.Acrobat,version=1.1.0.0, Culture Neutral,PulicKeyToken=null" or one of its dependencies.Access is Denied

Please help me

If I understand a file is stored in a folder on another computer. You want to open the file from an application which is installed on your computer with two different users... If yes, I don't think it's a good idea to open a file by two different users using the same application.

Thank u very much for the reply
I am not using two different users.In the program when i impersonate and then that user takes the control.

Is the Acrobat process launched by the correct impersonate user? You can check that in the Task Manager.
