I am working on Robohelp 5 and i am facing a very strange error.

I am unable to generate a Micsoft HTML help which is my primary layout. Whereas i am able to generate other forms of output. It throws this error while compilation

Fatal error: Unexpected error from Microsoft HTML help

When i try to open the .chm file , i get the following error:

Cannot open the file: mk:@MSITStore:F:\..........\.chm

However, i was able to generate the same .chm file from the same source file a month ago.

Hi,

How deep is the path to your Help project and the .chm file? The HTML Help compiler can't cope with paths that exceed 256 characters, and will consequently spit out corrupt .chm files.

Hi,

The path of my file is definitely not 256 characters long.

Last week i installed Adobe FM 8, i think this may be a reason where some registry files must have got corrupted which is causing this. I have even repaired my OS soon after that to replace the deregistered system files.

Even today morning i faced the same compiler error with my robohelp source file. Kindly help me out with this.

Thanks!!

Is this limited to one project or can you not create a CHM form any project. If the former, you'll need to identify what in your project is causing the compile to choke. Look at what has been added and go from there. If the later, try ensuring that you have all the relevant components. You can do this by running this diagnostics tool.

Read the RoboColum(n).

No, it is only limited to the generation of a single source file. I am able to generated flash, webpro and other output formats from the same source file. Only generation of html help is throwing this compiler error. And i have not added anything new to it. All i have done is installed Adobe FM last week. May be that may have deregistered a few dll s needed. But then again i have repaired my OS post FM installation. Still it is not compiling. Please help!

You are definitely using RH HTML and not RoboHelp for Word? This is a problem that does occur with CHMs from RoboHelp for Word and there is information in the Troubleshooting topic in that forum category.
