MS Reader cannot open file Either it is not signed with a trusted
certificate, or one of its components cannot be found. blah blah blah
I can open the same files on my laptop but not on the Ipaq, HELP.
Unfortunately, as with many error mesages, the "certificate" jazz is a
proverbial red herring. That's a standard Windows Mobile error message
displayed when a program can't start for any one of a number of reasons.
Hopefully, your problem is the same one I had on my WM6 AT&T Tilt (HTC
Kaiser), since I managed to figure it out.
For whatever reason, while Reader installed fine on my WM5 devices, it
did something weird on my Tilt. When Reader installs, it normally creates
a subfolder in the My Documents folder called "Annotations" to hold
information about the books you're reading, like the last page read, etc.
However, instead of a folder, it created a zero-byte _file_ on my Tilt,
called Annotations instead. Apparently, if Reader can't write
information about a book to the Annotations folder, it refuses to open
that book, resulting in the "missing components/certificates/etc." error
message.
For me, the solution was easy enough- delete the file named "Annotations"
and manually create a _folder_ called Annotations, and Reader opened
books fine from that point on. (Except I still couldn't activate it, but
I chronicled that workaround in my post in the "Windows Mobile 6.1
Professional & Microsoft Reader Activation" thread!)
