I can't read registry key with facter

[nicolas boquet]

Hello,

 

I've a problem with the module "facter/util/registry"...

 

i want to read key / value from registry. On windows x86, it's OK but in on windows x64, i've this error:

ERROR: The system was unable to find the specified registry key or value.

 

 

i 've create a fact to know the version of ocs inventory and the version of fusioninventory-agent:

this line work

Facter::Util::Registry.hklm_read('SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\OCS Inventory Agent', 'DisplayVersion')

but this line doesn't work

Facter::Util::Registry.hklm_read('SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\FusionInventory-Agent', 'DisplayVersion')

 

 

 

for exemple, in cmd.exe, i can do:

C:\Windows\System32\reg.exe export "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\FusionInventory-Agent" "C:\Uninstall.reg"

=> it's ok, i've my file uninstall.reg with my key FusionInventory-Agent

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\FusionInventory-Agent]
"DisplayName"="FusionInventory Agent 2.3.6 (x64 edition)"
"DisplayVersion"="2.3.6"
........

 

but with facter:

Facter::Util::Resolution.exec('C:\Windows\System32\reg.exe export "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\FusionInventory-Agent" "C:\Uninstall.reg"')

ERROR: The system was unable to find the specified registry key or value.

 

In fact, i want to know if it's possible with facter to read a 64 bit registry from facter...

 

Thank you and sorry for my english...

Nicolas,

 It is possible. Have a look at this recent write up I did - http://puppetlabs.com/blog/how-avoid-common-windows-gotchas-puppet (it even has a code example to do EXACTLY what you are asking).

It's works.

 

I've create 2 functions in my fact

 

def key_exists?(path_reg)
  begin
    Win32::Registry::HKEY_LOCAL_MACHINE.open(path_reg, ::Win32::Registry::KEY_READ | 0x100 )
    return true
  rescue
    return false
  end
end

 

def readkey(path_reg,value)
  begin
    mykey = Win32::Registry.open(Win32::Registry::HKEY_LOCAL_MACHINE,path_reg,Win32::Registry::Constants::KEY_READ | 0x100)
    return mykey[value]
  rescue
    return false
  end
end
