Re: [WiX-users] registry search overridden when "Program Files" encountered

ProgramFilesFolder = "Program Files (x86)" -> http://msdn.microsoft.com/en-us/library/aa370881.aspx
ProgramFiles64Folder = "Program Files" -> http://msdn.microsoft.com/en-us/library/aa370880.aspx

You can't write to 64-bit locations from 32-bit processes such as msiexec running your x86 package. Either make a x64 package or live with it.

Subject: [WiX-users] registry search overridden when "Program Files" encountered

Hi,

I have the following problem installing to a path read from the registry.
I'm using WIX 3.5 (and currently testing on a Win7 64-bit).

I'm doing a registry search like this:

      <Property Id="APPINSTALLDIR">
         <RegistrySearch Id='TheAppPath' Type='raw'
           Root='HKCU' Key='Software\MyApplication' Name='Path' />
      </Property>

Then I use it like this:

      <Directory Id='TARGETDIR' Name='SourceDir'>
         <Directory Id='ProgramFilesFolder' Name='PFiles'>
            <Directory Id='MyCompany' Name='MyCompany'>
               <Directory Id="APPINSTALLDIR" Name="MyProduct">
                  <!-- etc. etc. -->
               </Directory>
            </Directory>
         </Directory>
      </Directory>

I'm expected to install in the path read from Registry, or if it's missing
under (32-bit) Program Files\MyCompany\MyProduct.
I must mention that the target platform for the project is x86.

Everything works fine when the Path value does not start with "C:\Program
Files" (for intance C:\Program Files\MyCompany\MyProduct). In this case
somehow the property is always set to "C:\Program Files (x86)\etcetc" (i.e.
C:\Program Files (x86)\MyCompany\MyProduct). Obviously I don't want that. I
guess the Windows Installer thinks he knows better and replaces it, but I
want to install to that exact location. If for instance Path is "C:\my
Program Files\etcetc\" then there is no problem.

Has anyone ran into this problem and knows the cause? I need to find a
solution for this.

Thank you very much,
Marius Bancila
