Issue

When you try to generate a merged project from Adobe RoboHelp 6, you receive these error messages:

"Internal error encountered, Failed to generate WebHelp."

and

"Warning: [path to file] cannot be copied to [path to output]. reason: source does not exist."

This can occur if you have a relative link in your project that points to a location that is not contained within your project.

Update RoboHelp HTML to resolve this issue.

Backup the MpjSingleSource.dll file:

Browse to the [Path to the RoboHelp 6 application]\RoboHelp 6.0\RoboHTML folder. The default location for RoboHelp X5 is C:\Program Files\Adobe\RoboHelp 6.0\RoboHTML.
Rename MpjSingleSource.dll to MpjSingleSource.old.

Install the update:

Download kb401652.zip.
Unzip kb401652.zip.
Move MpjSingleSource.dll from the location you extracted it to, to the [Path to the RoboHelp 6 application]\RoboHelp 6.0\RoboHTML folder.
