It's been a while since I last fired up Orbiter, but isn't the log file generated upon first run?
If so, did you copy your whole Orbiter installation or did you perform a clean install?
I copied the whole Orbiter install, and did first run. I had a CTD, but no Orbiter.log file to look at. Also, I can't edit any .cfg files. I get an access denied error.
Because dumping program data into the program files folder isn't friendly to a multi-user environment, which is what Windows is.Since Vista, Microsoft had the brilliant idea that programs can't modify anything in Program Files folder. You need to run Orbiter as an administrator if you want to have Orbiter in that folder. Otherwise just move it somewhere else.
Yes, gone are the days when all of program's data could be nicely contained in Program Files...
