I have been having difficulty installing a particular program (Microsoft Flight Simulator X).
When I run the install application, Windows 7 pops up an error ...
"setup.exe - Entry Point Not Found The procedure entry point sfc.os.SfcIsFileProtected could not be located in the dynamic link library sfc.dll."
sfc.dll is in the system32 directory of Windows.
I can press OK and the installation proceeds until I start working with the installation settings. It is at that point the installation ceases with :
"Unhandled Exception Error Number: 0x80040707 Description: DLL function call crashed: ISRT._BrowseForFolder Setup will now terminate." Upon exiting, "InstallDriver Module has stopped working"
The entry point error first appeared when I tried to run a previously installed MSFS X. I would get a similar error (the bulk was the same, but I'm not sure about the file name). I have not encountered this error starting any other application (yet). I opted to uninstall and reinstall hoping that that would resolve the error. But now I am getting the error trying to reinstall the application from the DVD.
I have tried a system restore as far back as what points were available, but the restore failed on two different attempts (regular and via Windows 7 repair). I did an sfc /scannow and it identified errors but was unable to fix them. I finally tried a Windows 7 repair from the repair options on the installation DVD. This did not identify any problems to repair.
Neither BitDefender nor MalwareBytes had identified any threats.
I am hoping someone here can lead me to a successful repair or replacement of this dll (if indeed this is the problem.)
Here are some specs of my system ...
