Hello all, I downloaded a program "Disk Investigator" to see about undeleting previous deleted files. Needless to say, the program was a bit beyond my computer comprehension so I therefore decided to delete the program. I then went to control panel...add/delete....and deleted it there. I also went to c\program files and tried to delete the file there but an error message read.....Cannot delete di.exe...Access is denied...The source file may be in use.....I went to Task Manager to see if it was running there and it wasn't. I also checked processes and found di.exe and considered, end process, but a warning message read.....can cause undesired results including loss of data and system instability. The process will not be given the chance to save its state or data before it is terminated......my question is....How can I delete this di.exe and was the warning in task manager a "DO NOT ATTEMPT" endeavor? Thanks for any help or explaination!
