I'm having the same problems that several others have reported here: During virtually every flight, certain sound files that I expect to hear do not play. Missing sounds occur randomly and may include my VCP, taxi instructions, any level of ATC, and AI chatter.
In this forum, these symptoms are usually attributed to a bad installation, and the solution offered is to follow the procedure described in the post, "How to rectify a suspected bad installation" (it refers to a file named "Xinstall3.exe" which does not exist in my computer) and to update using the Accumulative Updater.
I think I've read every post on this forum related to missing sound files and applied the suggested remedies, but the problem persists. I have reinstalled 6 or 7 times, at least 3 times after completely uninstalling PFE and starting from a clean slate.
I've emailed the debug log files from the first two flights immediately after my last complete uninstall and reinstall. Here are the details of my last install:
Windows 7, 64 bit, FS9, UAC off, anti-virus disabled, FSUIPC V 3.980A. Installation was done in safe mode. All install executable files were run with administrator privileges in XP compatibility mode. Immediately after the install I applied the Accumulative Updater in command line mode. I recently found a thread entitled, "Clerance sound problem," in which you provided additional command line steps, which I followed. I ran Makerunways.exe after first deleting the csv files, then rebuilt the PFE database.
I've tried disabling add ons such as 3rd party aircraft, scenery and weather programs. I've redownloaded and reinstalled FSUIPC. I've followed the guidelines offered here on designing a proper flight plan, and I've tested using plans from the North American Sightseeing Tour. None of these steps have made any difference. My computer was purchased in May of this year and Windows has the latest updates.
Sometimes after a flight, I try to close down PFE and receive a popup saying, "Error reading hotkey hit locations," but I have never modified the hotkey configuration.
PFE is such a great improvement over the default ATC, it's hard to contemplate going back. Any ideas on how to correct these problems?
