I do a silent deployment of Adobe Reader XI and the setup doesn't set Adobe Reader as default PDF Reader.
I can set the default Reader manually but it has to be done automatically.
msiexec /i "AcroRead.msi" /q TRANSFORMS="TransformFile.mst" msiexec /i "AcroRead.msi" /q TRANSFORMS="TransformFile.mst" IW_DEFAULT_VERB=Read msiexec /i "AcroRead.msi" /q IW_DEFAULT_VERB=Read
Adobe Reader installs fine but it doesn't set itself as default Reader. I have to open the Reader manually and set it in settings again. But this is impractical.
The same problem is described by another user here. Does someone know how to fix it?
