While trying to open CHM files I get an error:"Navigation to the webpage was canceled"

No details available. Just to say that I opened 1 CHM file successfully, but all the rest as described above.

Hi hirsh007,

Follow the steps listed below:

 

Step 1:

a. Click Start, type cmd, right-click and select Run as administrator.

b. Enter the following command and hit Enter:

 

regsvr32 hhctrl.ocx

 

After getting the success message "DllRegisterServer in hhctrl.ocx succeeded", try to open your CHM file again.

 

Step 2:

 

If you are sure that the help documentation is from a trusted source, try and open it by following the below steps:

 

a.    Right-click the CHM file and click “Properties”.

b.    In the “General” tab of the “Properties” dialog box, click the “Unblock” button under “Security” at the bottom.

c.    Click “Apply” and “OK” to save the settings.

 

Try opening the .CHM files and check if that fixes the issue.

 

Step 3: Perform a System File Checker (SFC) scan

 

SFC toolscans system files and replaces incorrect versions of the system files by using the correct versions.

 

See How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7

 

Hope this information helps.

Do you open the CHM on a network drive/share?

I was also getting the Navigation Cancelled error on chm files (windows 7 32-bit). When i looked at the properties, i did not have any "Unblock" button. Instead, I had to go to the file's properties -> advanced -> and uncheck the "File is ready for archiving" checkbox. After that, the CHM opened properly.

I have Win7 and a CHM file on a network share opens with "Navigation to the webpage was cancelled". I don't have any "unblock" button and I have not managed to fix this. If I copy the CHM file to a local drive, it opens OK.
