N8 certificates not trusted/don't match the name

Well I worked out for myself how to verify the certificates are genuine:

• Using a desktop computer
• Go to the page with the certificates
• Select a certificate
• It will say either:
  • Certificate already exists - this confirms that the certificate on the website matches one already in your browser, which we already trust, therefore the certificate on the website is trustworthy
  • Asks if you want to install the certificate, DON'T.
    • First view the certificate details.
    • Copy the certificate serial number or SHA1/SHA256/MD5/etc hash
    • Paste this into a search engine
    • If another website that you trust lists the certificate, e.g. your phone manufacturer or another trusted website (preferably a secure website, therefore you have confidence the website is genuine), then you can trust the certificate
    • If no trustworthy sites are returned in the search then try another hash or serial number
    • If you can't find any trustworthy sites listing the certificate then I suggest you don't trust it.
• Finally, if you decide you trust a certificate then you can download and install on your phone.

 

WM6 and trusted certificates - installing software

I am unable to install software on my T Mobile Wing. I have tried Microsoft Reader and Scrabble. Both times I get the message on my device:



“Installation was unsuccessful. The program or setting cannot be installed because it is not digitally signed with a trusted certificate”.

Hi Paul,

I suggest you to follow the below and check if it helps.

For Microsoft Edge:
