Regwrite Reg_Dword does not write correct value

[Emiel Wieldraaijer]

Hi All,

The following code does not write hex ffffffff but hex 7fffffff.

$HKCU = "HKEY_CURRENT_USER"
If @OSArch = "X64" Then
	$HKCU &= "64"
EndIf

Msgbox (64, "HEX", Hex(4294967295))

RegWrite($HKCU & "\Software\Microsoft\Test", "Test", "REG_DWORD", "4294967295")
MsgBox(64, "Information",  RegRead($HKCU & "\Software\Microsoft\Test\", "Test"))

If i use 2147483647 (which is the result of the above) instead of 4294967295 it return the correct value. So it looks like it only happens when using 4294967295 (FFFFFFFF)

When using 0xFFFFFFFF it writes the correct Hex Value

Just extra quote

RegWrite($HKCU & "\Software\Microsoft\Test", "Test", "REG_DWORD", 4294967295)

and it works "fine" at least under Win7 X86

Without the "" it works perfect

but if you read the help the "" are always used

or there must be a modification to the helpfile or this is still a bug on X64

Help File Example

; Write a single REG_SZ value
RegWrite("HKEY_CURRENT_USER\Software\Test", "TestKey", "REG_SZ", "Hello this is a test")
