WiX Bootstrapper doesn't start/work - wix

Question

Ive a problemm with my wix bootstrapper to install .Net 4 and my application(.msi generated with wix 3.7). When i compile my solution everything is ok, and the generated exe has the right size(not sure if important, when i use winrar to open the exe there are just a few files in it, and not the files i want to install).
When i double click my exe nothing happens(with and without administrator).

Have you tried including the "Compressed" attribute for your MSIPackage entry? For example:
<Chain>
<!-- TODO: Define the list of chained packages. -->
<PackageGroupRef Id="Netfx4Full"/>
<MsiPackage Id="Myapp" SourceFile="$(var.Myapp.TargetPath)" Compressed="yes" Vital="yes" />
</Chain>
The "Compressed" attribute tells Burn to include your msi in the generated bootstrapper package. The "Vital" attribute tells Burn that your msi is required.
Also, burn packages write logs to your temp. directory. So look in there if it still fails.
