Installing .appx without trusted certificate?

Question

I have a Windows 8 app that I would like to deploy to my Windows RT 2. I only have the .appx, and I would like to just install it for testing by bypassing the s

Answer 1

Doesn't work for me. I still get the error after installing the certificate

If you received the message,

Either you need a new certificate installed for this app package, or you need a new app package with trusted certificates. Your system administrator or the app developer can help. A certificate chain processed, but terminated in a root certificate which isn't trusted (0x800B0109)

after renew your certificate, than probably your certificate is a temporary one and the simple way to solve it is make it usable.

To correct this error you need to change the position of certificate to root trusted certificates folder. When you click in your certificate, appear a page that ask you where you want to install it. So, there, you need to change to root trusted certificate folder and not use the default.
