Hi Walter,
I have tried to reproduce your issue on our machine, unfortunately I was not successful in reproducing your issue.
I have tried following scenarios:
1. Standard engineering machine configuration - win 7 32-bit Enterprise version and try to install Config Tool
2. Standard engineering machine configuration - win 7 32-bit Enterprise version with your dll you sent and try to install Config Tool
3. Clean windows 7 Professional 32-bit installation in my Virtual box and try to install Config Tool
4. Clean windows 7 Professional 32-bit installation in my Virtual box with with your dll you sent and try to install Config Tool.
In all cases I have been successful to install and run the Config Tools without any issues.
Seems that there is some strange deep issue with oleaut32.dll and your system configuration.
As a last chance you can try to install new clean virtual windows machine and try to install Config Tools if it helps.
I have already logged this issue into our system as a bug.
Will you inform if any solution will be available for your case.
