AVR-Chat

I downloaded the latest build of AVR Studio, and it will NOT install.  
After about 5-10 seconds,  saing "Astudio4b528 has generated errors, and 
will be closed by Windows.  You will need to restart the program.  An 
error log is being created."

I am unable to find any such log file, however. I have used the Search 
for Files feature, and searched for all log files.  None seem ot match 
this occurance, based on date/time.  Anyone with any ideas?
