Can’t open MDT 2012 task sequence zip file in Adobe Reader
I used a lot of times the VMware Horizon View Optimization Guide for Windows 7 and Windows 8 which can be found here. In the new version there is an attachment (MDT 2012 Task Sequence File.zip) which can’t be save or open. You got the following error messages:
Save the attachment
Open the attachment
I tried it with Adobe Reader and Adobe Acrobat. It looks like that some file extensions are blocked for security reasons by default in Adobe Acrobat/Reader and zip files are one of them. To avoid this behavior open the Registry editor in Windows and search for the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\11.0\FeatureLockDown\cDefaultLaunchAttachmentPerms
The version number in this path can be replaced by other version starting with 8.0. In this path you find the string value tBuiltInPermList with a lot of file extensions and numbers. At the end you will find this values:
z:3|.zip:3|.zlo:3|.zoo:3|.pdf:2|.fdf:2|.jar:3|.pkg:3|.tool:3|.term:3
Change the value |.zip:3| to |.zip:2| or |.zip:1|.
What does that values mean?
- 3 = never allowed
- 2 = always allowed
- 1 = user prompted
- 0 = restrictive user prompt
Now close the Registry editor and restart Adobe Acrobat/Reader for the changes to take affect.
