Accessing files in %windir%\system32 folder from 32-bit MSI

[mdavtec]

My MSI file is build as 32-bit and I want to file version of a DLL in %windir%\system32 folder. I tried using "Set 64 Bit Mode" command and then use $WINSYSDIR$ folder.

++
~InstallAware Clipboard Data~
~Get File Version~
~{0A88D5B9-6674-4960-98DA-5FEEB9B462CE}~
~$WINSYSDIR$\FOO.dll~
~DLLFileVersion~
~Set 64 Bit Mode~
~{36CB7CDA-B4B1-41B1-81D5-0C2A281D67CF}~
~FALSE~
~FALSE~
~TRUE~
++

But this is now working. It still get file version of DLL in SysWow64 folder. Any suggestion what can I do here? Also if I want to revert back to original mode, i.e. undo Set 64 bit mode, how would I do that.

I see following Warning in your online help fo "Set 64 bit Mode".
When applications are running on 64 bit Windows in 32 bit compatibility mode, Windows redirects file system and registry access to alternate 32 bit compatibility locations. This may cause undesired behavior with your setup if you call the Set 64 Bit Mode command after other commands that access the file system and registry.

Is that the reason, I'm not able to access file in System32.

Dear Mdavtec,

you should instead;

Code: Select all

Set Variable FILE_VERSION to 
Set Variable WINSYSDIR_X64 to 
Set x64 - Native 64 bit Windows, AMD64 and EM64T Architectures - installation mode
Get Folder Location System->System Directory into WINSYSDIR_X64
Get File Version $WINSYSDIR_X64$\FOO.dll into Variable FILE_VERSION
Set Win32 - Native 32 bit Windows and Windows 32 on Windows 64 (WOW64) - installation mode

Code: Select all

~InstallAware Clipboard Data~
~Set 64 Bit Mode~

~FILE_VERSION~
~Get Folder Location~

~~
~Set Variable~
~{7929DAD6-89AE-415D-8F7F-01C9753FAB99}~

Thanks for the reply. That was helpful in resolving the issue.

I'm, in general, curious about this 32-bit or 64-bit installation. Does InstallAware has any documentation giving details and providing guidelines to users. Some of the questions I've,
- Can I use 32-bit installation program to install 64-bit application?
- What user should do if application is supported on both, x86 and x64, platform?

Thanks.
