# Help Files

Security updates to Microsoft Windows have introduced some severe restrictions for accessing HTML Help (CHM) files across network drives. Under Windows most file links in HTML Help files will now generally not work at all and HTML Help itself is also severely restricted. Without registry changes on the user's computer, HTML Help now cannot be used at all on networks. This has an effect on the FluidFlow Network Version as all client machines that try to display the Help file will receive a "Page not found" message. More details and a fix for this problem are available on the Help & Manual (http://www.helpandmanual.com/products_hhreg.html) website. Alternatively, there is a workaround to allow a client machine to display Network-based HTML Help files, but it does involve modifying the Registry on the client machine. To do this: 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 Note: If this registry subkey does not exist, create it. To do this, follow these steps: a. On the 'Edit' menu, point to 'New', and then click 'Key'. b. Type 'ItssRestrictions', and then press 'ENTER'. 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'. This will allow you to access CHM files on a shared network folder. For more information see: http://support.microsoft.com/?kbid=896054 Note: Always make a backup of the Registry before making any modifications so that you can 'rollback' the changes if anything goes awry. To do this, run Regedit, select the 'File | Export' menu item, select the 'All' option from 'Export Range', enter a filename and click 'Save'. You can later use the 'File | Import' menu item if you want to revert to your original Registry. # Help Files on the Network - Alternative Solution FluidFlow also supports browser-based help. If you wish to use this please download the FF3BHELP.ZIP file from our website - https://portal.fluidflowinfo.com/ffdownloads/v3/FF3BHelp.zip - and unzip it to the [FluidFlow3 folder]\Help folder to give: "[FluidFlow3 folder]\Help\FFEnglish" and "[FluidFlow3 folder]\Help\QuickStart" folders. For FluidFlow3 to use this, create PSFF.INI - if it does not already exist - in the same folder as PSFF.EXE and add an 'Options | UseBrowserHTMLHelp' entry: [Options] UseBrowserHTMLHelp=1
