On the 15th of may I could still make new forms. Today 27th of May I wanted to fill a form which I use to make my bills. For some unknown reasons I is impossible to get the form on my screen. I use Infopath on a local win7 machine.
When I try to open I get a message "Infopath has encountered an eror. Operation failed."
When I try to design a new form or I want re-design a form I get also a message: "Some of the custom controls cannot be used, you can continu working without these custom controls, or you can modify them.
When I checked the details I get four times Invalaid Syntax and the last sentence is "The control definition file does not have a valid format."
I allready spend three days to find a solution. But without any success.
Maybe it started after a windows update?! I don't know. But maybe someone can help me to solve this problem.
