I think I got the x64 thing resolved from my last post. I still have
other
questions I posted, but the Any CPU for the solution properties and the
x64
for the setup, must still compile to x86 and not x64
I changed the solution properties to x64 and then rebuilt and
re-installed
,
and then the get registry value worked.
Would this be the correct method?

Hello Jeff,
Yes, compiling for x86 is the correct and most simple solution! In
this
case, our application can be installed on both of the x86 and x64
platform.
Just the application itself is x86 version.
But if we want to compile it as x64 version, the built application can
only
be installed on x64 platform, other than x86. In this case, we will
meet
the
error you mentioned in your first post because the setup and our
application
itself have mismatch platform version. The setup is x86 and writes
registry
key to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\, but our application
is
x64.
So the registry access is not directed. It reads directly from
HKEY_LOCAL_MACHINE\SOFTWARE\. So, if we want to compile an x64
version,
we
need to select the Setup project. And in the Properties window, we
change
the TargetPlatform from x86 to x64. This makes the setup matches the
version
of our application. So the registry location will be consistent.
But please note that the x64 version application can make full usage
of
the
x64 machine’s resource and will have better performance, but it will
not
run in the x86 client machines.
For more information about x64 registry redirection, please read the
following KB article

Colbert, thank you very much this helps a great deal.
So, I downloaded and installed SQL Compact 3.5 SP1 x64 (x86 was
apparently
already installed according to my attempt to install it).
My quesiton is this - suppose I want to compile for both platforms -
as
I
may never know which OS a person might have.
Do I have to have two projects, or do I have to compile the same one
2
times
one each, can I automatically build both.
Which leads me back to my question - if I compiled for x64, do I
understand
correctly, that my logic that was looking for
HKLM/SOFTWARE/Manufacturer/Program would automatically be
re-directed
to
the
Wow6432Node
I worked around this by changing project to compile for x86
yesterday,
but
I
don't know if this is the correct solution.
Much appreciated.

Hello Jeff,
Thanks for using Microsoft Newsgroup Support Service, this is
Colbert
Zhou
[MSFT] and I will be working on this issue with you.
The following are some explanations for what the Wow6432Node is in
the
registry and why we encounter the first issue. And later I will
give
my
solutions to both of your questions.
*The Wow6432 registry entry indicates that you're running a 64-bit
version
of Windows. The OS uses this key to present a separate view of
HKEY_LOCAL_MACHINE\SOFTWARE for 32-bit applications that run on a
64-bit
version of Windows. If a 32-bit application queries or writes a
value
under
the HKEY_LOCAL_MACHINE\SOFTWARE\<company>\<product>, it is
redirected
to
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\<company>\<product> by
system.
*In our situation, by default our MSI install program is 32 bit and
it
tries to write a value to HKLM\SOFTWARE. As a result of we are
running
on
64 bit system, this registry writing is redirected to
HKLM\SOFTWARE\Wow6432Node. But, our application is compiled as 64
bit
application. So later when it tries to read the registry key, it
reads
from
HKLM\SOFTWARE directly where the written key does not exist.
THE SOLUTIONS (It depends whether you want to compile your
application
as
32 bit or 64 bit)
*If we want to compile it as 32 bit just like we did in the XP
system.
Changing the option from Any CPU to x86. This will resolve both the
issue
1
and issue 2.
*If we want to compile it as 64 bit application.
1) To resolve the first issue, we need to select the deployment
project.
And in the Properties window, we change the TargetPlatform from x86
to
x64.
This makes your registry key is written in HKLM\SOFTWARE instead of
the
Wow6432Node.
2) To resolve the second issue, please download and install the SQL
Server
Compact 3.5 SP1 x64 version,
http://www.microsoft.com/downloads/details.aspx?FamilyId=DC614AEE-7E1C-4881-
9C32-3A6CE53384D9&displaylang=en#filelist
Please also not the Additional Information in that link,
"Due to changes in SQL Server Compact SP1 and additional 64-bit
version
support, centrally installed and mixed mode environments of 32-bit
version
of SQL Server Compact 3.5 and 64-bit version of SQL Server Compact
3.5
SP1
can create what appear to be intermittent problems. To minimize the
potential for conflicts, and to enable platform neutral deployment
of
managed client applications, centrally installing the 64-bit
version
of
SQL
Server Compact 3.5 SP1 using the Windows Installer (MSI) file also
requires
installing the 32-bit version of SQL Server Compact 3.5 SP1 MSI
file.
For
applications that only require native 64-bit, private deployment of
the
64-bit version of SQL Server Compact 3.5 SP1 can be utilized."
If you have any future questions or concerns, please feel free to
let
me
know! Have a nice day!
