Cannot open chm file

Hi,
I've found several threads on this site conserning error
messages containing: mk:@MSITStore , but none of them seems to fit
my situation.
I worked in RH on a project, generated a new chm file a
couple of times a day. No problem. Then suddently after generating
another time I could not open the chm - not from within RH project,
not from the folder, not when copying the (newly generated) chm to
the desktop.
The message is: "Cannot open the file:
mk:@MSITStore:C:\Program Files\RoboHelp Office...\..\filename.chm"
I've shortened it here with a couple of folders, but no it is
not very deep. I'ts at the same level as my other projects, so
that's not the problem.
I can open older chm files generated from other projects as
before, so there is nothing wrong with the help function itself.
I've tried deleting the chm file, rebooting my pc, regenerating -
but no result.
I also tried the MJ's Diagnostics and the only problem found
was:
HTML Help 1.x Workshop Components*** HH Workshop not found or
not installed correctly. Try reinstalling.
But it seems like this 1.x is something very old and my
installation has worked up until now. Do I really need to reinstall
something and exacly what and how? Is this an RH component or MS
component?
Any clues are welcome.
Thanks
Sara

Hi John,
Thanks for trying to help out. It's solved now. I should have
written the solution here right away, but I was so happy that I
could continue with my work so I forgot about it.)
What I did was that I looked at the single source layout and
I thought that Optimize CHM File Size might cause a problem (a shot
in the dark - but you have to try everthing). I deselected it and
regenerated. Voila - it worked. Then, with trembeling hands, I
selected it again and regenerated - it still worked. Maybe this
change of the layout made it save again properly and restart from
scratch. But i thought that I had tried a similar thing before when
a made new layouts to see if they would work, and they didn't.
So, it's solved, but I'm not really sure what was wrong and
what solved it.

896358: Cannot open CHM files

I hope this isn't indicative of MS's patch quality continuing to take a nosedive.
I need for certain users to be able to open CHM files from a network share. Easy cheesy. Sadly the 'workarounds' seem to function (or not) wildly differently across OS versions and architecture.
I have Win7 64 and 32 bit machines. 64 bit work fine when the 'allowed' URLs are specified in the registry (HKLM\Software\Microsoft\HTMLhelp\1.x\ItssRestrictions - value UrlAllowList). No zone modification needed.
However;
32 bit Win 7 machines do not work with this method. Unless the user is a local administrator (not happening). I cannot get them to work at all. Can anyone please help me understand what needs to be done differently for these clients?
Thanks!

Hi n4,
Have you tried to add a MaxAllowedZone value under the registry key?
HKLM\Software\Microsoft\HTMLhelp\1.x\ItssRestrictions
If not, you may take a try:
1. Right-click the ItssRestrictions subkey, point to New, and then click DWORD Value.
2. Type MaxAllowedZone, and then press Enter.
3. Right-click the MaxAllowedZone value, and then click Modify.
4. In the Value data box, type 1, and then click OK.
5. Quit Registry Editor.
If the above steps do not work for you, please see
http://support.microsoft.com/kb/896358 for alternatives.

Cannot open .CHM file when Application is running in Service Mode.

Hello All,
I have a compiled HTML help file (.CHM) that i am trying to
integrate with my VB 6.0 project.
I am using RH_ShowHelp function (which uses htmlhelp()) to
launch the Help File.
All is fine when i run my program in Application Mode.
But, when i install my app in Service Mode, (running under
SYSTEM account) - it does not work.
I have tried to use ShellExecute API as well, and that does
not work either.
Does anyone have any suggestions on how to get this working
from services mode?
Is there some other function call or parameters needed...
Any input is appreciated.
Thanks
G

Software executed as a service is usually running as a
background task and
is usually executed not by the current logged-in user but by
a special
default "user" named "System". There are a number of
advantages to having
software run as a service... it can run continuously no
matter who's logged
into the system or even if the system is locked.

Error opening CHM file (Cannot open the file: mk:@MSITStore)

Hi,
I'm getting an error opening a CHM file (Cannot open the file: mk:@MSITStore). I have tried the following solutions, but neither of them worked:
Deleted the CPD file, reopened the project, and recompiled.
Ran MJ's Diagnostics report and recompiled.
I'm using RH10 and Windows 7.
I have lots of other projects, and none of them result in this error. I can't think of anything else to fix it. I have seen a few threads on this issue, but none of them have lead me to any solutions that work for me. I'm hoping that starting a new thread will provide visibility and allow someone to share a solution.
Thanks,
Amy

---UPDATE---
I was able to fix this by generating the WebHelp and then regenerating the CHM file. I'm not sure why this worked, but it did.
However, I'm also seeing this issue with a different project now, and this "fix" isn't fixing that one. So I still need an actual solution. At least for now, the first project is "fixed."
Thanks!
Amy

Please help me in solving the same

HI,
Thanks for the response.
I am really tensed for the same...
Actually the error occurs in the following case:
1. I am creating a Parent folder in robohelp with the name ABC..
2. Next Under ABC i have created 2 separate folders say XYZ and EFG.
3. Under XYZ i have created various Topics say 2 or 3.
4. Under EFG i have created various Topics say 7 or 8.
5. Now, i have created a TOC with name for ABC (Parent Folder.)
6. Next i have dragged and dropped my two sub folders that i have created under ABC in Project Set up wizard that is XYZ and EFG, in order to generate the webhelp first and then the CHM file fo rthe same.
7. Webhelp is successfully getting generated.
8. But when i convert the Webhelp to CHM Converter, after few seconds the robohelp gets halt and it shuts up the robohelp, showing a message dialog box that the Adobe Robohelp 11 is Troubleshooting for the error, the Windows manager will get back to you..Someting like this, the .CHM file for the same gets generated on the described path, but when i click on it, it does not open and shows the error as "Cannot open file: mk:@MSITStore: C:\\Users\..\Desktop\filename.chm".
Please help me in sorting the above issue.
According to me:
I think i am Lacking in the two things:
1. How to link all the topics with the parent folder.
2. How to Merge the projects.
Can you please provide me the link where i can get tutorial to create a TOC for multiple files in a same TOC and to generate a chm for them.
Actually for single project folder i have worked successfully. But, its first time i have to create a chm with lot many sub folders in it, as like one create a book.
Please help
Thanks & Regards,
dhm

Cannot open the file: mk:@MSITStore

I just upgraded to RoboHelp 8 for Word (Office 2007, XP Pro) and continue to have this problem after compiling a project (Microsoft HTML) and clicking on view. One suggestion was to change the path closer to the root directory. I changed the output path the C:\ (can't get any closer than that!) and that didn't help. I searched the forum for a definitive fix but haven't found one yet. The file opens fine using explorer but it's obviously a pain-in-the-butt to have to always do that. Thanks.

I also compile my Help projects using the .chm format. I have a handful of users at one site that are not able to open the Help files. When they click on the Help from the application, it looks like it thinks about it, but then nothing happens. When I had them try to open the Help files directly from their local directory, they received the following: Cannot open the file: mk:@MSITStore:C:\Program Files\....\HelpFile.chm.
I have tried recompiling the .chm file. I have tried recompiling the .chm file so it was closer to my root directory. I have had the client "Unblock" the Properties of the .chm file. None of these solutions fixed their issue. (I posted the .chm file on our ftp site for the user to save down and replace their other Help file.)
Besides the things I've tried, other posts suggest the users go into their registry files to manipulate the Hhctrl.ocx. What other solutions are out there? I don't think I can feasibly tell another customer that they should try to update their registry files. I am able to access the HelpFile.chm from multiple computers from our site and have not had issues.
Thanks for your help!

Mk:@MSITStore error while opening CHM file

Hi,
I have placed a CHM file (generated using RoboHelp
X5) in the network folder. When opened from there, it is
throwing this error:
Cannot open the file : mk:@MSITStore: <path where file
is located with file name>.
This error is thrown only for one or two files and not
all the CHM files in that network folder. Why so?
What is the reason and how to resolve this? Please
help!
Thanks and regards,
Krishna

P Krishna:
The CHM will not open from a network drive. This is a
security issue. There ia a work around it but it involves editing
the registry of all your users (which could be a formidable task).
Girl from Ipanema:
If it will not open locally it could be due to the manner in
which the CHM file got to the local drive. The latest Windows XP
(and I assume Vista, too) will block any CHM that was simply copied
to your hard drive. To resolve this, right click on the CHM in
Windows Explorer, select Properties, and "Unblock."
Hope this helps,
John

Error when opening .chm file

I converted a .Winhelp help project to HTML and generated
.chm file. The .chm file opens just fine on my local hard drive.
Then I check in this .chm file into Visual Source Safe where we
store all of our files. When I get a copy or check out this same
.chm file from Visual Source Safe on to my local hard drive, it
refuses to open and displays the error message:
Cannot open the file:
mk:@MSITStore:C:\SOURCESAFE\Enterprise\ENT5.0\Documentation\Help\CHM\ptwin.chm
The same behavior occurs even when other people get a copy of
this file on to their hard drive. How can I resolve this problem?
Thank you in advance!

Hi Mandavilli,
This
thread suggests that the chm file has become corrupted somehow,
and that deleting the CPD file and recompiling solved the issue,
although there is no mention of VSS. It might be worth trying, in
any case.

Did you try to open teh fle by double-clicking its icon? If the file was made with an older version of Office, you may get that message. Try opeing PP and, from its "File" menu, see if you can open the ppt. I've foundthat often gets around that message and then yo ucan save the file from the newer version.
If that doesn't work, consider asking in the Microsoft Office: Mac forums here:

PowerPoint is not an Apple product and it seems a lot of people around here avoid Office.

This could be a Launch Services issue. The following article describes how to manually reset Launch Services — the notes at the bottom of the article also provide information about the side effects of deleting each of the files involved:
Resetting Launch Services
If you prefer using a cache cleaning utility instead of following the manual procedure described in the previous article, take a look at this other article for general troubleshooting and cache-cleaning procedures. Actually, you should also verify/repair the startup disk (not just permissions), as described there:
Resolving Disk, Permission, and Cache Corruption
The most appropriate utility for this particular problem probably is Tiger Cache Cleaner, but you may also want to consider other utilities, such as OnyX, or Cache Out X, which are free. Whatever utility you choose, be sure to read this first:
Side effects of System cache cleaning
As an example, this is how you should proceed with OnyX:
1. Quit all applications.
2. Launch OnyX and enter your administrator password.
3. Go to Maintenance > Reset and check LaunchServices database.
4. Un-check any other pre-checked options.
5. Click the Execute button.
6. Restart the computer.
BTW, if you’re running Mac OS X 10.4 (Tiger), as your profile indicates, it would have been more appropriate to discuss this in the Mail & Address Book - Tiger forum. If the discussion applies to both Mail 1.x and Mail 2.x, it doesn’t really matter, but it’s difficult to know that in advance.

I cannot open pdf files from one supplier when using Adobe Reader but I can using another Viewer

I cannot open pdf files from one supplier when using Adobe Reader but I can open it if using Google PDF viewer or another viewer. The Adobe reader gives the error "There was an error opening this document. The file is damaged and could not be repaired" when I try to open the file. The version of Adobe Reader is 10.1.7, however I have tried other versions and they all fail the same way. I have tested on a number of different PC's in different networks and all fail using Adobe Reader but work using alternate viewer. Also the PC's will open a PDF from any other source.

Newer Reader versions are more strict than older versions (and other PDF viewers). If certain minimum requirements are not met, Reader will tell you that the PDF is damaged. This can happen when a document was created with software that does not adhere to PDF standards, or when the file was damaged during a download or email transmission.
You should contact the creator of these PDFs.

Photoshop Elements 9 and cannot open Raw files from my Canon EOS 1000D camera.

I am using Photoshop Elements 9 on a Windows 7 based PC and would like to know why I cannot open Raw files produced by my Canon EOS 1000D camera.
I have checked the version of the plug in as 6.5 for raw files which is supposed to open .cr2 files and should be compatible according to Adobe site info.
any ideas for next move.
Mick

Hi,
According to all of Adobe's charts, the Canon 1000D should be supported by the basic PSE 9 even without updates. When you said you checked the camera raw version in PSE, did you do that by going to the Help menu and selecting About plugins -> Camera raw?
The Canon 1200D requires ACR 8.4 which is only compatible with PSE 12 - so for PSE 10 your brother would need the DNG converter.
I can't find a sample raw file to try (I do have PSE 9). If you want to upload a sample file to dropbox and give me access, I could try it on my system.
Have you tried opening one of your files on your brothers system?

I cannot open a file from LR5 into CC2014 unless it is a smart object. also will not save back to LR at all it gives me an error message "Line: 1 - photoshop.notifyLightroomDocClosed ('lightroom-2.0', 'B53AFA39-A49B-4709-A9BD-0B6467C175C3', 'Macintosh H

I cannot open a file from lightroom into CC2014 unless I open it as a smart object. CC opens, just will not display my image. i am given an error code when I save an image, and can only save to my desktop or other locations, not automatically back into my lightroom.
I am using LR5 latest update, as well as CC2014
Below is the error message:
Line: 1 -> photoshop.notifyLightroomDocClosed ('lightroom-2.0', 'B53AFA39-A49B-4709-A9BD-0B6467C175C3', 'Macintosh HD:Users:BPexposures:Desktop:_DSC5962 as Smart Object-1.psd');

I was also having this issue, and I did some more searching and found this answer in the Adobe forums: Re: Photos from Lightroom 5 to Photoshop CC (2014) and back.... The issue appears to be caused by having not updated Lightroom to the latest version prior to having CC2014 installed (wow that's stupid). The trick seems to be to uninstall Photoshop CC2014 and to then reinstall it after having upgraded to Lightroom 5.5.

I have photoshop CC. I cannot open two files such as Tiffs and view them side by side. When I open the second file it overrides the first. Do I need to do something with preferences?

What happens when you try to use the clone stamp tool?
It should work with the images side by side.
You can setup photoshop cc to be like photoshop cs2 was on your other mac, by going to Photoshop>Preferences>Interface and unchecking
Open Documents as Tabs and Enable Floating Document Window Docking
And also going to Window and unchecking Application Frame
