Issue/Introduction
Description:
Dmscript.exe is a 32 bit executable and every access to HKEY_LOCAL_MACHINE\SOFTWARE key is automatically redirected to the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node
Example:
DIM hkey1 AS INTEGER
hkey1=RegOpenKey(HKEY_LOCAL_MACHINE, "SOFTWARE\ComputerAssociates\HostUUID")
IF hkey1=0 THEN
Print("Could not open registry key HKLM\SOFTWARE\ComputerAssociates\HostUUID")
END IF
On a Windows 64 bit machine, this script will open the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ComputerAssociates\HostUUID
How to open the registry keys under HKEY_LOCAL_MACHINE\SOFTWARE without redirection to Wow6432Node on a 64 bit OS?
Solution:
Use function SetMode64(true) to disable the redirection to Wow6432Node
Example:
DIM hkey1 AS INTEGER
SetMode64(True) hkey1=RegOpenKey(HKEY_LOCAL_MACHINE, "SOFTWARE\ComputerAssociates\HostUUID")
IF hkey1=0 THEN
Print("Could not open registry key HKLM\SOFTWARE\ComputerAssociates\HostUUID")
END IF
In this example the DMS script will open the key HKLM\SOFTWARE\ComputerAssociates\HostUUID even if it is executed on a 64 bit Windows OS.
Use SetMode64(False) to enable again the redirection to Wow6432Node
Remark:
The function SetMode64() has no effect on a 32 bit machine and the example above is applicable on a 64 bit OS.
