My system:  
window vista  
visual studio 2005  
windows mobile professional sdk  
windows mobile standard sdk  
PVRSDK\_VERSION "2.06.26.0649"  
  
I try creating a hello world app first and run it on the emulator ok  
  
Then I compile the sample but when try to running say   
  
"the file ‘OGLES2Initialization’ cannot be opened. Either it is not signed with a trusted certificate, or one of its components cannot be found. If the problem persist Try resintalling or restoring the file.  
  
Same happen when running the exe files from binariesdemos folder.  
  
So looks like i need to install or copy something to run this demos?
