visual studio .net general: I have purchased a digital certificate from Thawte.com and want to use it to
sign a CAB file generated by an existing working device deployment project.

I have gone into the properties on the deployment project and have selected
my certificate from the store (I have also signed the application projtec
too). When the CAB file has been built, if I right-click the file in Windows
Explorer on my PC and go into properties, I am able to see that my
certificate has been successfully applied to the CAB file.

I then copy the CAB file down to my Windows Mobile 5.0 device using
ActiveSync. When I tap the CAB file on the device, it pops up a window saying
that the program is from an unknown publisher just as it does when the CAB
file is not signed.

What am I doing wrong?

Hi Mike,

I am afriad we don't support the mobile device development issue in this
newsgroup. I suggest you can consult this issue in our corresponding MSDN
forum , wish you'd get more quick and better answer there:

Smart Devices General
http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=34&SiteID=1

and the following newsgroup:

microsoft.public.win32.programmer.wince

By the way, I have perform some research on this issue, it seems you need
to use the Mobile operator to sign your cab file, please refer to the
following articles for the details:
