setup project .net 4 prerequisite

Question

See more:

I added .net framework 4 to my setup package as a prerequisite, when installing this package an error reports that installing .net 4 require WIC "windows imaging component" ,which I've added as a prerequisite also.

but installation failed due to a newer version of this component already installed.

I want to ask how to check whether this WIC is installed or not and skip installing it when there is a newer version?

thanks

The installer for the prerequisite is what should be doing the checking, not your installer.

<PackageFiles>
<PackageFile Name="wic_x86_enu.exe"/>
</PackageFiles>

<commands>
<command packagefile="wic_x86_enu.exe" arguments="" />
<installchecks>
<msiproductcheck property="IsMsiInstalled" product="‎61 46 9e cb 00 04 00 00 00 65">

You apparently have no idea how software installers work. I recommend that you do some research.
