The marscore.dll on my computer is supposedly missing. I don't know how it went missing, when it went missing, or how. The PC apparently needs it for running the "Help" and "System Restore" and "System Information" facilities. This of course means I can't access the "Help" system, view "Systems INFO" or use "System Restore". There are probably other things that I can't do as well that I haven't yet come across.

I've tried downloading the .dll from places online and putting them in the correct places: in the "binaries" SECTION of the PC Health file in Windows, and in Windows\System 32. But nothing happens. It still doesn't work.

I haven't got a Windows XP Home Operating Systems disc (I do have the XP Service Pack 2 Disc), so I can't use that to replace files. The computer (Compaq Presario) came pre-installed with XP Home Edition when I bought it from Sears.

THANKS...ncSkeet

reboot pc and keep tapping the f8 key and chose the last good config option....and have you kept up with your updates..Thanks for your suggestion. I rebooted and did the F8 thing, and it made no difference. And yes, I check for updates daily.

ncSkeetYou will most likely have to format and reinstall Windows XP.

I once removed a .DLL (Due to Pest Patrol saying it was spyware) and I ended up with not being able to access 1. Help function 2. Device manager 3. Services.msc and perhaps other things that I overlooked.

You should obtain a (legal) copy of Windows XP, having an Operating System on a CD is a must.ncSkeet......Re your issue...did you not receive a set of rescue/restore disks from Sears with your pc.....? How long have you had it ?
The other odd thing is I have 2 pcs each with XP Hoime on them and SP2.....and neither has marscore.dll on them.....searched all files hidden and otherwise and in the registry as well ....no trace of it. Both these machines work fine.
I was doing some looking online and I see referance to that dll being used in Win95/98/ me  but not xp home or xp Pro....
Exactly what was it you were trying to do when this issue POPPED up ?

let us know

I ordered my PC online from Sears, and there was nothing there about sending an extra copy of the OS on disc. What kind of disc does the "Compaq Recovery CD-DVD Creator" in my Start menu make? Due to my current financial situation, I am unable to purchase another copy of XP on disc.

I first noticed the problem on Tuesday when I tried to open "Help & Support" from my Start menu. When I Googled it I had read where the same situation with "Marscore DLL" had  caused similar problems for others with "System Information" and "System Restore", so I checked and it had done the same to my system. It actually appears to be a relatively common problem that is extremely difficult to fix. I also read where the problem may be the result of running a program called "Easy Cleaner" from ToniArts. I do have that program, so I tried the fix for it that ToniArts has on their website, but it  didn't help.

I appreciate your responses. Since I have discovered that a lot of folks would benefit from it, I would still like to think that their is a solution for this problem that doesn't involve formating and reinstalling Windows XP. But after getting advice from experts like y'all I'm about to give up hope for that.

Thanks...ncSkeetncSkeet....I have never had to use a restore disk.....so I am not in a position to offer a fix for your dilema..but I was under the impression that you should be able to create your own recover disks from the software which came with your pc ......Have you Emailed Sears (or better yet spoken to someone there about your problem) ......and what about Compaq/HP.......can they offer no help. The other thing you could try is......click.....
Start /All programs/Accessories/System Tools.....then select either system information or system restore.
What happens if you click on ...Cnrl/Alt/Del......does your task manager open......?.
The other thing that comes to mind is .....the program you have called Easy cleaner....does it not have a log file in it which would indicate what it has removed and possibly even have backups of your system .....

dl65  The marscore.dll on my computer is supposedly missing. I don't know how it went missing, when it went missing, or how. The PC apparently needs it for running the "Help" and "System Restore" and "System Information" facilities. This of course means I can't access the "Help" system, view "Systems Info" or use "System Restore" by any means. I still get the "marscore .dll is missing" window if I try to access any of those functions, even though I have downloaded and installed that .dll as described in my other posts. There are probably other things that I can't do as well that I haven't yet come across.

I haven't yet spoken to or emailed Sears or Compaq. It's been over a year since I bought this computer so any Warranty has expired. What kind of disc does the "Compaq Recovery CD-DVD Creator" in my Start menu make?

I went back to "Easy Cleaner" and undid everything I had done. (This is in addition to using the so-called "fix" for the problem from their website.) And yes, I can still access the Task Manager, by using both the c+a+d option and right-clicking on the taskbar.

ncSkeetthis is suppose to fix your problem    fixwinxphelp.vbs search this site for it   >http://www.dougknox.com/    and easy cleaner did the damage a newer version has fix that problem if you wish to use it?>http://personal.inet.fi/business/toniarts/ecleane.htmYeah, I had already tried that as mentioned (see Reply #5 ).
I went ahead and did it again from Doug's site, but it made no difference.

ncSkeetrecheck your updates as marscore dll was fix by msoft..contact the place were you bought it from and ask them for the dvd recovery disk ...without it you may have even more problems...your system is load with an image of winxp home ...the recovery disk regcognises this image..and is not transferable..
