Bug #52352 .net connector install fails due to missing machine.config bug fix

Description:
The connector assumes a machine.config file if the CONFIG directory exists, it should just skip over that version if there is no machine.config.

How to repeat:
Have a config folder in a .net version without a machine.config inside (seems this can occur with older versions of .net)

Suggested fix:
ensure machine.config exists before trying to do edits on it.

Hi Nick and thanks for your catch.

I do not believe .NET FW is of much use without machine.config but we should check anyways.

Definitely is of no use, problem is old versions of .net may exist in this situation (basically uninstalled but a few folders remaining) so when the connector goes to install itself into every .net version setup fails and rolls back because it can't properly handle the situation of a missing machine.config in older version.

have you heard of this error also affecting the unistall/ repair from running on a  machine.  I currently have a situation where I am needing to reinstall the connector, but i get an error when trying to repair or unistall it.

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:
