.NET CF 3.5 Messages cab error not a valid WEC Setup file

I downloaded the * NETCFv35.Messages.EN.wm.cab installer from here to allow “to convert error numbers to readable string messages” as suggested.

I used it on a different project on VF61 CE6 and it just went as expected, now I’m trying to install it on a T20 WEC7 and I get the message “The file is not a valid Windows Embedded Compact Setup file”, preventing me to actually install it.
Any clues?

Also, do I really need it? I had a few chances already to make my testing application fail in doing an HTTPS request and I was able to clearly see the stack frame of the exception. Maybe is not needed on WEC7?

Thank you

The particular CAB file is designed to be used for WinCE4-WinCE5. If you are satisfied with the verbosity level of error messages on WinCE7, there is no need to install that CAB file

Here is another version of this cab file I found in my PC:
ToradexNETCFv35.Messages.EN.cab (800.6 KB)

I do not know from where it comes from or what it does, so whoever is reading, take it with a pinch of salt.
I found it asI was now experiencing the same issue on another project running on VF61 CE6, and I knew I had it somewhere cause it did work for me in the past.
So now I found it, and it does install smoothly also on my T20 CE7, and show proper exception messages now.
Hope it helps.
