I do something similar:
In Product.wxs:
<CustomAction Id="CA_DISPLAY_UPGRADE_DETECTED" BinaryKey="BIN_CustomAction"
DllEntry="DisplayUpgradeMessage" Impersonate="yes" Execute="immediate"
Return="check" />
<UI>
<ProgressText Action="CA_DISPLAY_UPGRADE_DETECTED">CA: Verify if this is
an upgrade...</ProgressText>
</UI>
<InstallUISequence>
<Custom Action="CA_DISPLAY_UPGRADE_DETECTED"
Before="MigrateFeatureStates">WIX_UPGRADE_DETECTED</Custom>
Then in my custom action DLL I have a method DisplayUpgradeMessage:
var result =
session.Message(
InstallMessage.User + (int)MessageBoxIcon.Warning +
(int)MessageBoxButtons.YesNo,
new Record
{
FormatString =
"Setup has detected that a previous version
of " + productName + " is currently installed."
+ "\nWould you like to perform an upgrade?"
});
if (result == MessageResult.No)
{
// User had decided to halt the install
return ActionResult.UserExit;
}
