Can't open chm files: "Cannot open the file: mk:@MSITStore..

Archived from groups: microsoft.public.windowsxp.general (More info?)

Tonight I tried opening a chm file and it failed, with that error message.
This happens for any chm file I have tried. I don't know when this broke, I
know I used to be able to open chm files with no trouble but I can't
pinpoint the last time it worked.

I've searched around and found some references to this, but no solution --
the only relevant MSKB is for Win98. I tried regsvr32 hhctrl.ocx, deleting
the hh.dat files, clearing IE's file cache; nothing has helped. I haven't
made any significant recent changed to the system that I can think of.

Any suggestions are appreciated -- this is will be a problem if I don't
resolve it, and I can't think of what else to try.

I'm running XP Pro/SP2, fully patched through Windows Update.

Thanks in advance for any suggestions.

Thank you for the quick response.

The .chm files are local (but I ran into the network share problem at work
last week though!)

But regsvr32 itss did the trick!

Thanks again!

Hi Ramesh,
I had a similar problem. All the .chm files I downloaded can't open. I
don't get any warning message though and the command you suggested
doesn't seem to solve the problem. What I get is "DllRegisterServer in
itss suceeded", but still won't open the files. What could be wrong??!

Thanks

look here

http://support.microsoft.com/kb/902225

Open cmd and type:
regsvr32 %systemroot%\system32\hhctrl.ocx
then
regsvr32 %systemroot%\system32\itss.dll

And see if it works

Another fix...

After trying every possible fix out there, re-installing files, reinstalling hh.exe, registering the files again and so on... nothing worked. Kept on getting the same error message:

Can't open chm files: "Cannot open the file: mk:@MSITStore..

I finally found out that the error was caused because the name of the directory containing the .chm files
had non-English characters. After changing the directory's name to simple English - everything works.

Hope this helps any of the frustrated people out there looking for a solution,

regsrv32 itss didn't work for me but this worked perfectly... from http://www.drexplain.com/press/chm [...] yed-error/

level 1 was all I needed

Solution: Modify the ItssRestrictions registry entry to enable a specific security zone.
Follow these steps:
1. Run 'regedit' command from the command line.
2. Locate and then click the following subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions
Note: If this registry subkey does not exist, then create it.
3. Right-click the ItssRestrictions subkey, point to New, and then click DWORD Value.
4. Type MaxAllowedZone, and then press ENTER.
5. Right-click the MaxAllowedZone value, and then click Modify.
6. In the Value data box, type a number from 0 and 4, and then click OK.
The values settings are
0 = My Computer
1 = Local Intranet Zone
2 = Trusted sites Zone
3 = Internet Zone
4 = Restricted Sites Zone
