Statistica network version are started from a network drive, so under the secuity policy of InternetExplorer and Winhlp32 those files show not up in the correct way on a workstation. To fix that behaviour a registry patch must be applied. This also can be done with the Group Policy settings.

Both registry patches must be applied on the workstation computer:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000002

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\HHRestrictions]
"MaxAllowedZone"=dword:00000002

How to unblock .hlp files that are stored on the intranet

Network administrators can use the Allow WinHlp32.exe to access .hlp files stored on intranet sites policy setting to unblock .hlp files that are stored on the intranet. Administrators can use the GPCM to manage this Group Policy setting. For more information about Group Policy, see the "References" section.

The feature to block or to unblock .hlp files that are stored on intranet sites: To change this setting, users must first add the following new subkey to the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WinHelp
Then, users must add a DWORD value that is named AllowIntranetAccess to this subkey.

If the value for AllowIntranetAccess is set to 1, the .hlp files that are stored on intranet sites will be available. 
If the value is set to 0, the .hlp files that are stored on intranet sites will be blocked. 
If this registry value does not exist, the .hlp files that are stored on intranet sites will be blocked.
