Summary: Marscore.dll appears in some error scenarios. Aside from running the system file checker, what to do isn't clear.

When I select "help and support" I get a warning: marscore.dll not found. What should I do?

My first approach would be to perform a system file check (See What is the system file checker and how do I run it? ). I've seen various references around about marscore.dll issues but no definitive answers. If that fixes your problem I'd love to hear about it.

Tried all of the above but still unsolved...exact same issue...steps followed...

P.S. save yourself some command line work by going to the system32 folder and pasting a shortcut for the cmd.exe file into the task bar...tap on it to use.

1. Ran cmd and enter "net stop helpsvc"
2. Checked the following applications are not running: helpsvc.exe helphost.exe helpctr.exe
3. cd c:\windows\pchealth\helpctr\binaries
4. typed: "start /wait helpsvc /svchost netsvcs /regserver /install"
5. lots of churning and grinding sounds
6. typed in: "net start helpsvc"
7. error...net was not recognized this time
8. typed in: "start helpsvc"
9. more churning
10. same result...error message...cannot find marscore.dll
11. back to square one

Any more suggestions.

I ran SFC/ scannow and it fixed the "marscore.dll" problem, and restored the Help and system restore functions. Nothing else was needed. I did not even have to use the Windows XP Install CD. Thanks for the suggestion, Leo!

I also was a victom of Dll Archive. I found this post on google but didn't realize that the page I wound up on wasn't all the comments. I was getting ready to reinstall Windows XP when I found Matthews post of 4/18/05. This did the trick, the file needed was dataspec.xml Found it in C:\Windows\ServicePackFiles\i386
Thanks David
