When Installing I get an "Error opening file for writing" message. The file is HudfuncsApp.exe. I have tried several times and get the message each time. When I ignore the message and complete the install the program does Launch but then freezes and crashes. My other problem is that since trying to install HM2 I can not get HM1 to work either I have even tried uninstalling and reinstalling but this has not worked. So at the moment I do not have a functioning copy of either version.
