I am glad it helped.

What I have suggested shouldn't normally be needed, but we have met situations in the past where it was necessary. Still not sure what's the root cause, though.

Best regards

OK, that's weird.

Can you please re-run the Setup program, select the "custom" installation (on the 2nd wizard page), and then, when it makes to the Installation Components page with the tree of component, make sure that

Assemblies (.NET Framework) -> Embedded assemblies

is also checked (this is turned off by default).

It might help
Thank you

Hello,

in order to rule out that this is not somehow related to PHP only, can you try one of the VBScript examples that come with the product as well? Does it work, or does it give some error - and if so, is it the same error?

Thank you
