[NTG-context] AcroRd32 Runtime Error

Hallo, I have updated my context after a very long time. The first test run does not work because an initally dde attempt to acroread. I got the following errormessage: Microsoft Visual C++ Runtime Library Runtime Error! Program: C:\Programme\Adobe\Reader 9.0\Reader\AcroRd32.exe This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. I have Acrobat Reader Version 9.4.6. This is working ok with pdf files and this has worked ok with context prior to the update. What can I do to solve the problem? Wolfgang
