I'm working in Robhelp for Word 7 and up until last week I was able to view the results of my compiled help in Robohelp. When the file is done compiling and I try to click 'View Results,' I now get 'Cannot open the file: mk:@msitstore:x\doc_4x\ap\output\flexi\fap32.chm. Now I can go to my output folder in Windows Explorer and open the .chm with no problems, but I can't view my results while in RoboHelp. Tried the View Primary Layout icon as well and get the same error message. I've gone to the website that tells you to download the .ocx file and re-register it. I've removed any software I had recently loaded on my machine. Nothing works. I've even deleted the RHTemp# directories.

How I solved the Cannot open the file: mk@MSITStore issue. (Moreover, my chm was suddenly 2x standart size.)

Downloaded & ran MJsDiag.exe , which reported: File not found: C:\Program Files\itcc.dll.

Copied the dll from a windows32 subdirectory on my C:\ drive (which I can't find at the moment) to the Program Files directory. No change in results.

Returned to RH8, opened Single Source Layouts > Microsoft HTML Help > Properties dialog. In Additional Options, unflagged the Optimize CHM File Size check box. Flagged the Apply to all Topics check box, enabling the CSS radio button and the adjacent field, which listed default.css.

Left-clicked Finish button. Successfully generated .chm file (to my desktop) and found that the file had returned to the expected size, @ 49 MB.

You didn't say whether you definitely had reregistered the HHCTL.OCX file. Also which Windows OS are you using and where did you put the .OCX file. I had this problem last week on a WinXP machine after I had uninstalled some software but re-registering the file worked a treat.
