Windows 10 update and Certificate

Hello all,

In my Windev 20 project i use a call with soaprunxml(), it is with a certificate what is installed on the pc. By the call in my app the certificate is shown and the user has to click OK, just like in internet explorere. Works fine, till this morning when a user has the (big) update from Windows 10.
When the certificate should come i have an error 'this program is not working anymore' and it wil close directly.
Is there someone with the same problem?

Thanks,

Sammy
