There was an error during the IIS configuration process while trying to install Virtual directory 'Default Web Site//

I am receiving the error in the subject of this topic for the first time while installing my application on a customer's server. The chain of errors before this error seem to indicate there is something unique about their IIS configuration or an issue with the authentication from being set on the Virtual directory my application is setting up. The errors I believe are the culprit are:

COM Error [0xffffffff]: (Unknown error 0xFFFFFFFF)[ERR] Cannot execute Commit operation.
COM Error [0xffffffff]: (Unknown error 0xFFFFFFFF)[ERR] Could not set Authentication for 'Default Web Site/EIDSAGE100DIS'.
COM Error [0xffffffff]: (Unknown error 0xFFFFFFFF)[ERR] Could not set common entity properties.
COM Error [0xffffffff]: (Unknown error 0xFFFFFFFF)[ERR] Could not create WebApp/VDir, isWebApp = true

MSI (s) (98!4C) [14:01:26:173]: Product: Ei Dynamics - Sage 100 Contractor Data Integration Suite -- Error 4034. There was an error during the IIS configuration process while trying to install Virtual directory 'Default Web Site//EIDSAGE100DIS/'.

These are from the .log file generated using /L*V command line arguments. I was hoping you could help diagnose the issue. I am happy to provide the .aip and .log files but I am unable to attach them here.
