Last few nights were my sleepless nights as I couldn't either uninstall vmware player 4.0.2 version or install vmware player 4.0.4 version. I had to get rid of this FXSAPIDebuglogfile.txt file but I kept getting message saying its been used by another program.
finally, I found the solution :
1. Go to control panel click Programs \ Turn windows features on or off.
2. Scroll down the list and unchecked the box next to Print and Document Services so its not highlighted.
3. Click ok and restart your machine.
That file will go away after the restart.
But what is that file for? It's a log file that is associated with the fax application that you use.
