Error Accessing Help Files

[jussij]

For security reason, latter versions of Windows disable the execution of scripts and html codes which can mean certain help files fail to view.

To make these help files viewable the ItssRestrictions registry will need to be modified.

To do this use the regedit.exe utiltiy to import the following key details:

Code: Select all

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000001

In the registry details above set the MaxAllowedZone to suit.

The MaxAllowedZone controls the level of access as summarizes in the table below:

Code: Select all

+----------------+---------+----------+---------+----------+------------+
|                |  Local  |  Local   | Trusted |          | Restricted |
| MaxAllowedZone | Machine | Intranet |  Sites  | Internet |    Sites   |
+----------------+---------+----------+---------+----------+------------+
| 0              | Allowed | Blocked  | Blocked | Blocked  | Blocked    |
| 1              | Allowed | Allowed  | Blocked | Blocked  | Blocked    |
| 2              | Allowed | Allowed  | Allowed | Blocked  | Blocked    |
| 3              | Allowed | Allowed  | Allowed | Allowed  | Blocked    |
| 4              | Allowed | Allowed  | Allowed | Allowed  | Allowed    |
+----------------+---------+----------+---------+----------+------------+

Warning: Be careful when setting the maximum allowable zone, making sure to only enable those security zones that you trust.
