An error may occur when you try to open signed solutions by using the Open method in InfoPath 2007 or in InfoPath 2003 Service Pack 1
You can open signed solutions from the user interface (UI)
in Microsoft Office InfoPath 2007 or in Microsoft Office InfoPath 2003 Service Pack 1. However, if you try to open
signed solutions by using the
Open method of the object model (OM), you may receive the following
error message:
InfoPath cannot load this form.
The
signature on this form is not from a trusted publisher.
This problem occurs if all the following conditions are
true:
- The signed certificate comes from an un-trusted
root.
- The signed certificate is in your Trusted Publishers
list.
- You have a private key for the signed
certificate.
This problem may occur when you create a test certificate for
development purposes.
To work around this problem, follow these steps:
- Click Start, click Run,
and then type mmc in the Run dialog
box.
- On the File menu, click Add/Remove
Snap-In.
- Click Add.
- Click Certificates, and then click
Add.
- Click My user account, and then click
Finish.
- Click Close, and then click
OK.
- Expand the Certificates - Current User
node in Microsoft Management Console.
- Right-click the Trusted Root Certification Authorities
folder.
- On the All Tasks menu, click
Import.
- Follow the steps in the Certificate Import Wizard to import
the test certificate to the Trusted Root Certification
Authorities group.
Warning Be careful when you add certificates to this group. You do not
want to accidentally trust a third-party certificate.
Microsoft
has confirmed that this is a problem in the Microsoft products that are listed

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
Thank you for using kbAlertz.com Feedback System.
