SAP Help shows only empty sections or blank pages

SAP Help�pages will appear as blank screen, instead of displaying the text and/or graphics when you want to view the help document.

This issue can occur due to one of the following reasons:
�

• Existence of Internet Explorer 7.0
• Incorrect Windows registry entries for the SAP Help in the local Windows system.

�
Internet Explorer Release 7 is not completely compatible as release 6. SAP GUI uses Internet Explorer in the HTML control to display the help documents.

To resolve this issue, you need to either apply one of the SAP GUI patches mentioned below (or the latest one which is available from the SAP Market place):
�
SAP GUI for Windows 6.20 Patchlevel 64
SAP GUI for Windows 6.40 Patchlevel 20
SAP GUI for Windows 7.10
�
or uninstall Internet Explorer 7.0 (only applies to Windows XP or earlier OS.)
�
To know the version of Internet Explorer, follow the below mentioned steps:
�
1. Open Internet Explorer.
2. Click Help menu, About Internet Explorer.
�
If you are experiencing this issue with Internet Explorer 6, you need to add "MaxAllowedZone"�registry DWORD value in the following key:
�
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions\"
�
To add the key automatically, follow the steps mentioned below:
�

1. Open Windows Notepad (Click, Start, Run, notepad.exe)
   
2. Copy and paste the following code.
   
3. Save the notepad as "saphelp.vbs".
   
4. Double-click it to add the entry in to Windows registry automatically.
