With the below code it still crashes the bootstrapper at the first call to
MsiLocateComponentW: (the log file has the checking x64 Word PIA)
In the precomp.h header file I have added:
#include <Msi.h> // For MsiLocateComponent call
// To fix MSI linking errors
#pragma comment(lib, "msi.lib")
In the
WIX_ToolSet_v3.8\src\ext\BalExtension\wixstdba\WixStandardBootstrapperApplication.cpp
file I have:
DWORD dwFileAttributes = 0;
BOOL fValidateComponentExists = FALSE;
INSTALLSTATE installState = INSTALLSTATE_BROKEN;
LPWSTR sczPath = NULL;
DWORD cch = 0;
LPWSTR sczComponentIdx86 = L"{9FE736B7-B1EE-410C-8D07-082891C3DAC8}";
LPWSTR sczComponentIdx64 = L"{13C07AF5-B206-4A48-BB5B-B8022333E3CA}";
BalLog(BOOTSTRAPPER_LOG_LEVEL_STANDARD, "Checking the x86 version of the Word
PIA");
installState = MsiLocateComponentW((LPCWSTR)sczComponentIdx86, sczPath, &cch);
BalLog(BOOTSTRAPPER_LOG_LEVEL_STANDARD, "First call to MsiLocateComponentW, the
install state of x86 Word PIA: %ls", installState);
cch++;
hr = StrAlloc(&sczPath, cch);
ExitOnFailure(hr, "Failed to allocate string for component path.");
installState = MsiLocateComponentW((LPCWSTR)sczComponentIdx86, sczPath, &cch);
BalLog(BOOTSTRAPPER_LOG_LEVEL_STANDARD, "Second call to MsiLocatecomponentW,
the install state of x86 Word PIA: %ls", installState);
fValidateComponentExists = FileExistsEx(sczPath, &dwFileAttributes);
BalLog(BOOTSTRAPPER_LOG_LEVEL_STANDARD, "Retrieve the install path of x86 Word
PIA: %ls", sczPath);
// If the component is not installed or unknown AND the component path doesn't
exist fail
if ( (installState == INSTALLSTATE_UNKNOWN || installState ==
INSTALLSTATE_ABSENT) && !fValidateComponentExists )
{
BalLog(BOOTSTRAPPER_LOG_LEVEL_STANDARD, "InstallState of Word x86 PIA is
%ls", installState);
BalLog(BOOTSTRAPPER_LOG_LEVEL_STANDARD, "Install path of Word x86 PIA is
%ls", sczPath);
fValidateWordPIAInstalled = FALSE;
}

Subject: RE: Trying to use MsiLocatecomponent in Bootstrapper to check for a
Word PIA
Something to note is that in the first call to MsiLocateComponentW, the second
param (path buffer) must be NULL, and the third param (buffer size) must be
zero, or you will get INSTALLSTATE_INVALIDARGS. (And when you allocate a
larger buffer, prior to the first call, it returns INSTALLSTATE_UNKNOWN.) But
what I found curious was that when you make the first call with a NULL pointer
and zero size indicator, it returns INSTALLSTATE_LOCAL (rather than
INSTALLSTATE_MOREDATA, as documented). It also returns the size of the needed
buffer, without the terminator in cch. Others have pointed out in MSDN posts
that they used to get INSTALLSTATE_MOREDATA but a 'change' happened and they
are now observing INSTALLSTATE_LOCAL (returned by the initial call).
Initially I added a switch (installState) {....} of all possible return codes,
and then removed it to simplify the post. You will probably want to add code
to check the returns, being aware of the above behavior, which seems to differ
from the documentation.
