I want to add the prerequisites for my installer, I successfully added .net framework as prerequisites, but I wanted to add "k-lite codec pack" before installing my actual application.
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:util="http://schemas.microsoft.com/wix/UtilExtension" xmlns:bal="http://schemas.microsoft.com/wix/BalExtension">
<Bundle>
<Chain>
<ExePackage
SourceFile="..\Redist\KLite_Codec_Pack_1090_Full.exe"
DetectCondition="ExeDetectedVariable"
InstallCommand="/verysilent /ACTION=Install"
RepairCommand="/verysilent ACTION=Repair /hideconsole"
UninstallCommand="/verysilent ACTION=Uninstall /hideconsole"
Compressed="yes"
Permanent="yes"/>
</Chain>
</Bundle>
</Wix>
The above code solves my problem. by the installCommand /verysilent will install the klite pack silently.
