Check Pre-requisites

[wictor81]

Hi,

I've made an installer following the .Net Template. I need the installer to check if the .Net Framework 4 (and Client) are installed, inform the user and install it. But none of these screens are showing and the .Net Framework is not being installed. This is the main part of the MSIcode:

[DEFINE REGION: Check Application Pre-Requisites]
Comment: Check setup pre-requisites
Set Variable PREREQ to FALSE
Set Variable PRELIST to
[compiler if Variable BUILDMODE not Equals PATCH]
if Variable NEEDSUPGRADE Equals TRUE
Set Variable PREREQ to TRUE
Set Variable PRELIST to $PRELIST$$NEWLINE$Previous Version Uninstallation
end
Include Script: checkmsi31
Include Script: checknet4aip_client_x86
Include Script: checknet4aip_x86
[compiler end]

Dear Wictor81,

which OS did you use to test the package?

For what I see you are including .Net 4 (x86) RTMs, are you testing the package on a 32 bit target OS?
In addition on recent systems .Net 4.0 is not necessary, due the fact that an higher version of Net RTM is already included with the system.

Regards
