KB133: Problems Viewing VisualRATEX Help

Issue:Microsoft Security Issue
When you download the zip file, you may receive a security warning when you try to open the VRHelp.chm file.

Solution: If you receive this warning, you must UNCHECK the "Always Ask Before Opening This File" checkbox. Leaving the checkbox checked will not display the Help correctly.

If the above solution doesn't work, right-click the VRHelp.chm file and click “Properties.” Under the “General” tab, is there an “Unblock” button? If there is, click “Unblock” and try to view VisualRATEXHelp again.

Viewing VRHelp on a Network Drive

Microsoft recently released a security patch that makes it impossible to view .CHM files that are stored on a network drive (as opposed to .CHM files stored on your own computer). The help file will appear, but instead of the topic text you will see an error message "this page cannot be displayed".

If you trust all the computers on your LAN or intranet (and the people using them), you can lower the restrictions on the Local Intranet zone to allow .CHM files to be displayed with the following steps:

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions
3. If this registry subkey does not exist, create it.
4. Right-click the ItssRestrictions subkey, point to New, and then click DWORD Value.
5. Type MaxAllowedZone, and then press Enter.
6. Right-click the MaxAllowedZone value, and then click Modify.
7. In the Value data box, type 1, and then click OK.
8. Quit Registry Editor.
