On Windows, there is a utility called certutil.exe

If you'd run this, 

certutil -v -dump C:\<your-ca-file>.p12 

and share the output, this will help troubleshoot further.

Specifically, there will be a section Certificate Extensions, and if you will find 1.3.6.1.4.1.311.20.2: Certificate Template Name (Certificate Type): CA or SubCA - it is a kind of a certificate you need.

If it is a server certificate (as I am suspecting), you will find a section 

2.5.29.37: Enhanced Key Usage
Server Authentication (1.3.6.1.5.5.7.3.1)

or

Client Authentication (1.3.6.1.5.5.7.3.2)

then it is the wrong kind of certificate, and you'll need a CA-one.
