InfoPath Dev

Hi, I hope that someone can help me!

 I am running Infopath Version 14.1.4536.1000 (32-bit). Once I've loaded the document with Infopath, I click on the "Launch Content" button and I get the following errors:

Error 1:

Error 2:

Initialise Error
The input form cannot be opened for the following reason:
"The type initialiser for 'System.Windows.Media.FontFamily' threw an exception".

I know it's really long, but it's very urgent that I sort this problem out. I have spoken to support at MSN and they could not come up with a solution.

Please help me!!! :(

Hi,

You're not alone on the web. Lot of person have this error, but for a lot of reasons...

Can you tell us more about your form. Do you use managed code or is it a classic form?

With a simple form (that you didn't customize), have you the same error?

If yes, this is a client machine problem. You can try on other PC and the if it works.. 

• Some users tell to turn off the services "Windows Presentation Foundation Services" (but I think you are not in this case).  (http://social.expression.microsoft.com/Forums/en/web/thread/3bcf79c4-7600-49c2-8522-f19a58940019)
• For some users, it's a problem of configuration and environment variable (http://connect.microsoft.com/VisualStudio/feedback/details/522003/precreatedefaultfamilycollection-fails-on-application-startup)

 Hi

 Thank you so much for your response! But I haven't been able to solve the problem using those instructions, as I'm working on Windows 7.

Is there another suggestion you could make?

Thanks, I appreciate your help!
