[wix-users] Registry serach and numbers

[John Cooper]

The way I do it is I write a custom action to harvest the two pieces from the registry.  I then reassemble them using the Version() constructor to set a value with the custom action.  I take a property as input with the minimal version number.  It is also converted to a true Version() so I can use it's comparison semantics.  I then make the comparison and store a "#1" in a property if the version is greater than the minimum, or I clear the property otherwise.

Hi all

I have this condition to see if the IIS version is higher the 7.
But I have 10 and it will not recognize it as a higher number, and there for is says that I don't have IIS7 or higher installed.

This is the wix code.
<Property Id="IIS_MAJOR_VERSION">
      <RegistrySearch Id="CheckIISVersion"
                      Root="HKLM"
                      Key="SOFTWARE\Microsoft\InetStp"
                      Name="MajorVersion"
                      Type="raw"/>
    </Property>

    <Condition Message="IIS must be installed of at least IIS 7 or higher.">
      <![CDATA[Installed OR (IIS_MAJOR_VERSION >= "#7")]]>
    </Condition>

How do I solve this?
Can I convert the IIS_MAJOR_VERSION to an INTEGER or is there a better way to check the IIS version when the IIS version is higher then 9?
I understand why IIS_MAJOR_VERSION >= #7 is not true when IIS_MAJOR_VERSION is #10 since it's a string.

I'll take any idees.

/Ronny
