I am trying to understand the function of regread() with a program taken as an example: bandicamfree.
Supposedly the program is installed in "ProgramFiles" so the registry key is:
"HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Bandicam", "")
but when I run this:

$regPath = RegRead("HKLM64\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Bandicam", "") ;InstallLocation or UninstallString
If @error Then
    MsgBox(48, "1", "Error :" & @error, 4)
Else
    MsgBox(48, "2", "Error :" & @error, 4)
EndIf

;or
;@error > 0 with the same result: 1

whatever you do the result is always: 1
if the program is installed in "C:\Program Files\Bandicam" in a 64bit system why can't find the registry key?
or am I wrong about something? But if I do this:

$regPath = RegRead("HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Bandicam", "");InstallLocation
If @error Then
    MsgBox(48, "1", "Error :" & @error, 4)
Else
    MsgBox(48, "2", "Error :" & @error, 4)
EndIf

it works¬†ūü§®

Isn't locating a registry key of an installed program in: "C:\ProgramFiles(x86)\Bandicam" supposed to be: "WOW6432Node" on a 64bit system?

or am i doing something wrong?

Hello,

 

what's the output of this script?

$MyEnv="CPU = " & @CPUArch & @CRLF
$MyEnv &= "OS Arc = " & @OSArch & @CRLF
if @AutoItX64 Then
    $MyEnv &= "Autoit running X64" & @CRLF
Else
    $MyEnv &= "Autoit running x86" & @CRLF
EndIf
$MyEnv &= "Autoit version = " & @AutoItVersion

MsgBox(0, '', $MyEnv)

I wonder if it writes the to the 32 bit subsystem because the installer is 32 bits?

I assume, that this is the reason...

 

32bit actions are redirected to the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ registry key.

this code will return the 64bit in the SciTE output pane, followed by the 32bit part.

ConsoleWrite("HKLM: ----------------------------------------------------------------" & @CRLF)
$i=0
while 1
    $i+=1
    $KeyName=RegEnumKey("HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall",$i)

    $Err=@error
    if $Err Then ExitLoop
    ConsoleWrite("Instance " & $i & @TAB & $KeyName & @CRLF)
WEnd

ConsoleWrite("HKLM64: ----------------------------------------------------------------" & @CRLF)
$i=0
while 1
    $i+=1
    $KeyName=RegEnumKey("HKLM64\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall",$i)

    $Err=@error
    if $Err Then ExitLoop
    ConsoleWrite("Instance " & $i & @TAB & $KeyName & @CRLF)
WEnd

MsgBox(0, '', "done")

and that one will write and read back some value to 32 and 64 bit:

#RequireAdmin

$StrResult="Result:" & @CRLf

$Key="HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
$ValName="ThisIsThe32bitValue"
$Type="REG_DWORD"
$Wert=32
$result=RegWrite($Key,$ValName,$Type,$Wert)

$StrResult &= "Key: " & $Key & @CRLF & _
"Value Name: " & $ValName & @CRLF & _
"Type: " & $Type & @CRLF & _
"Value Data: " & $Wert & @CRLF & _
"@Error = " & @error & @CRLF
$ReadBack=RegRead($Key,$ValName)
$StrResult&="ReadBack: " & $ReadBack & @CRLF & _
"@Error = " & @error & @CRLF & @CRLF


$Key="HKLM64\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
$ValName="ThisIsThe64bitValue"
$Type="REG_DWORD"
$Wert=64
$result=RegWrite($Key,$ValName,$Type,$Wert)

$StrResult &= "Key: " & $Key & @CRLF & _
"Value Name: " & $ValName & @CRLF & _
"Type: " & $Type & @CRLF & _
"Value Data: " & $Wert & @CRLF & _
"@Error = " & @error & @CRLF
$ReadBack=RegRead($Key,$ValName)
$StrResult&="ReadBack: " & $ReadBack & @CRLF & _
"@Error = " & @error & @CRLF


MsgBox(0,"Result",$StrResult)
