Congratulations! Yasuki

To stop UAC from gegistry. First, Set UAC slider to lowest level and restart PC. Then, open registry eidtor,and open HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System Check values following 2 items. 1)EnableLUA 2)ConsentPromptBehaviorAdmin If values are not =0, change them to =0. And also check value for 3)FilterAdministrationToken Change to =1 if not. (Back up current setting before change!) And try to the prcedure again. This is very dangerous setting for security, please do not forget restore normal setting after install FSX. (Back up current setting before change!) I hope this works. In case it fails, Last thing to try is complete recovery OS. Your PC should have application for recovery, and may have some options in it. Choose option like "recovery with format drive C:" (Be careful, all files in your PC will be erased!!)

Our situation looks very similar! My case was that,I was running FSX on Windows8 Pro with no problem. But couple days ago, windows update install some update files automatically,and I restart my PC. After that, Windows8 never start??? So,I forced to "Refresh" Windows8 from DVD boot and success it, but all application were gone! Then I reinstall all applications including FSX and encounter 1722 error. Common point between my case and your case is having error 1722 after reinstall OS. Did you format your drive before reinstall OS? I did not format my drive, so Windows(old) folder was in drive C:. I remove windows(old) folder by disk cleanup, but I think some of files still having record of FSX and UAC prevent overwrite files. I succeeded reinstall FSX by UAC off,changing access rights and doing procedure I wrote yesterday. But your case, still having error, I think UAC causes this problem. Did you try shutting down UAC by registry edit? If no, I suggest trying it,then do procedure I wrote yesterday. And still having error, try format drive and reinstall OS. Yasuki.

If you just bought new PC and you have not install much apprications yet, Probablly, Reinstall OS might be best way to solve this problem. Try Recovery or clean install of Windows8 and activate Administrator account, turn off UAC,then install FSX again. And if that error happens again, might be some problem in Samsung PC. I hope not...

Oh! it didn't work!? Only one thing I can suggest is as follows. 1)When instaling FSX, stop UAC (Set lowest level) 2)Right click on drive C:,choose "property" ,and open "security" tab. "System" and "Administrator" should have "Full Control" rights, but other user doesn't. Change access right for "users" to "full control" I hope this works. Yasuki

I was same situation yesterday. It looks like Microsoft reset fix(MSKB928080) won't work as long as you log on. May be you have error messege in command window like "cannot delete token~". To solve this problem, 1)Activate administrator account on your Windows8 PC. Right click on lower left corner on screen and open command prompt(Administrator) and type "net user administrator /active:yes". 2)Log you off and log on as Administrator. 3)Download MSKB928080,and unzip.(You may already have this file,but you need download and unzip again.) 4)Open command prompt and excute MSKB928080.exe (May be you have messege "success" on the end of command line.) 5)Reinstall FSX 6)Log off and log on your account.
