[wix-users] SFXCA: Failed to start the CLR

[Christopher Painter]

Binding to the CLR happens well before your code runs so I doubt it has anything to do with with a web.config


Do you work in an industry where admins/security types are known for locking down machines?  (been there done that).  I'd run the .NET framework verification utility, possibly running a repair  and profile the activation.   Is this a one off problem machine or are you seeing it more often?

PS-  One of the things I like to do is have a dummy CA before AppSearch that simply spins up and sets a property like DOTNETVALID=1 and then use that in a LaunchCondition or similiar.  Think of it as a health check.

Rob would say that you can't be sure .NET will be 100% backwards compatible 10 years from now. That is true... but I think the rewards are worth the risk.

Hi Christopher

Yes, I haven't really seen any issues with this CA or DTF. It was built
with 3.5, probably about 6 years ago and compiled into a wixlib and hasn't
been touched since. I haven't been able to reproduce it. The only issue I
recall seeing is where admins locked down the root web.config, but the
typically failure in those cases happen at the end of the CA when it
attempts to save the modifications to the file. This is failing before
InstallFiles when the initialize step to generate the custom action data
for the deferred CA that does the actual work is suppose to run.

The CustomAction.config file itself has the following:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0.30319"/>
    </startup>
</configuration>
