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

[Christopher Painter]

I don't think Managed CAs are bad. :)


What version of WiX did you build it with?  What does your CustomAction.Config look like?  Can you reprod with a basic ca that only does a session.Log()?


DTF has been really solid for me over the years and I'd know what may or may not be going on here.

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

Hi

I've got a managed CA that I wrote years ago. I know, managed CAs are bad,
but this one actually fiddles with the root web.config so it's a necessary
evil. Recently a customer reported seeing the error below

SFXCA: Extracting custom action to temporary directory:
C:\Windows\Installer\MSI84B8.tmp-\
SFXCA: Binding to CLR version v4.0.30319
SFXCA: Failed to start the CLR. Error code 0x80070005

Typically when it runs successfully, you'd see something like

SFXCA: Extracting custom action to temporary directory:
C:\Windows\Installer\MSI1E57.tmp-\
SFXCA: Binding to CLR version v4.0.30319

The HRESULT has me puzzled since it indicates Access Denied. Could the
permissions on .NET be corrupted? Would running SubInAcl potentially fix it
or is there another option to consider exploring?

Thanks,
Jacques
