Get Registry Key on Windows 2008 Server 64 bit

[NewsArchive]

Ok, I have read over the other posts I found on Registry and 64bit os.

Still not sure why I am having the problem I am having.

Synopsis:
Get the SQL paths from the registry, so I know where to put the datafiles I
am installing/updating.

Code:
Set Variable %SQL_MSSQLKEY% to FUNCTION:Get Registry Key
Value("MyInstanceName") from
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance
Names\SQL"
If %_SB_ERRORCODE% Does Not Equal "0" Then
Set Variable %SQL_DATAPATH% to FUNCTION:Get Registry Key
Value("SQLDataRoot") from "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft
SQL Server\%SQL_MSSQLKEY%\Setup"
Set Variable %SQL_BACKUPPATH% to FUNCTION:Get Registry Key
Value("BackupDirectory") from
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL
Server\%SQL_MSSQLKEY%\MSSQLServer"
Else
Display Message Box "It appears there was an error accessing the
follow..." -- "Error Accessing Registry"
End

Results:
This works perfectly on any 32 bit OS, but it appears that on 64 bit OS, it
is looking in the Wow6432Node section. Since SQL registry keys aren't
there, I get errors.
So, how do I force access into the regular 64 bit area of the registry?

Notes:
Install IS code signed. This particular install is not using any clarion
apps. Simply installs a SQL MyDatabase.BAK file, and then runs a restore
script.

See "Set x64 Mode..." function. To read a 64-bit registry key, you have to
switch the application to 64-bit mode.

Don't forget to set it back to 32-bit after you handled your 64-bit stuff.
Otherwise, the installer continues in 64-bit mode.

Ok, this makes sense... how do you switch modes back and forth from 32 to 64
bit modes?

Thanks Friedrich!

See attached screenshot. If you set it to "Enable x64 Support" then the
installer will switch into 64-bit mode on 64-bit operating systems. If you
set it to "Disable x64 Support" then it will go back to 32-bit processing
mode.

In other words, before you read the 64-bit key, enable x64 mode. Then read
the key and after that, disable 64-bit mode so your installer continues in
32-bit.

Notes: I was doing some more research and was looking at the General
Information / Generator tab.
I was reading in the help file (yes, I actually use the help file! <grin>)
and set the Installer Type to 32/64 bit hybrid.

The Get Registry Key functions are now returning the correct values, but I
get an error right after the welcome screen.
"The specified module could not be found. (msls31.dll)"

I have no code in the dialog loop, and the only dialogs I am using is the
Welcome, License Agreement, and Finish. (Very basic install).

Still digging...

Thanks,

I assume, your application is not native 64-bit, so it does not make sense
to set the installer to 64-bit ;-)

You would use a hybrid 32-bit installer to install a 32-bit application on
32-bit Windows and a native 64-bit application on 64-bit Windows from the
same setup.exe.

Switch back your installer to 32-bit immediately <g> What you are doing is
not correct!

The following discusses your msls31.dll issue:

Awesome. Thanks for the help on both branches of this thread.
Will fix my RTF and go from there.
And, yes, I switched it back to 32 bit (Thank you, may I have another?) <g>
