This worked fine for us inside OnDetectComplete on Wix 3.8 (released
version). For example :
// Check if Acrobat is installed by reading variable.
LPWSTR sczAcrobatValue = NULL;
BalGetStringVariable(L"AcrobatInstalled", &sczAcrobatValue);
BalExitOnFailure(hr, "Failed to get AcrobatInstalled burn
variable.");
// Show warning state if Acrobat variable is empty.
if ((sczAcrobatValue == NULL) || (wcslen(sczAcrobatValue) == 0))
{
hr = m_pEngine->SetVariableString(L"AcrobatWarningState", L"");
BalExitOnFailure(hr, "Failed to set AcrobatWarningState burn
variable.");
}
AcrobatInstalled is read using Util: registry searches, and
AcrobatWarningState just controls visibility of a warning text box in our
custom theme. What specifically "doesn't work" ?
