Description
This article gives an installation tip when using Windows 7 and FortiClient. The installation of FortiClient may be impacted by the Windows 7 MaxNumFilters registry.
Scope
FortiClient v4.0 MR1 and above.
Solution
Windows 7 is hard coded to allow up to 14 filter drivers. By default the MaxNumFilters registry is set to 8. FortiClient will not install as the "9th" filter with the default value in the MaxNumFilters registry. The registry must be modified to the maximum value.
To manually modify the MaxNumFilters registry:
1. Click on Windows Start >Run >regedit and modify the file:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\MaxNumFilters
2. Manually modify the MaxNumFilters to 14.
To modify the MaxNumFilters registry using the msi editor:
1. Open and edit the FortiClient msi using Orca or InstEd and add the following to the registry table:
"Registry" = "MaxNumFilters"
"Root" = 2
"Key" = "SYSTEM\CurrentControlSet\Control\Network"
"Name" = "MaxNumFilters"
"Value" = "14"
"Component_" = "Comp_RegBasic" |
2. Save the FortiClient msi. Once the FortiClient msi installs this will be added to the Windows 7 registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\MaxNumFilters = 14
