Creating an instance of the COM component with CLSID {E1C5D730-7E97-4D8A-9E42-BBAE87C2059F} from the IClassFactory failed due to the following error: 80070005.

 Your error is a typical error message, if  IIS is not allowed to create instances of a  specific com component.

In order to make the webpart work, please perform the following steps:

1. Add access rights for the users IIS_IUSRS and NETWORKSERVICE to some DCOM-Components, which are:

-WIA Device Manager
-WIA Extension Host for 64 bit extensions

If you are not able to set any access permissions for this DCOM-Components - you have to take ownership to them via the registry, if you don't know how to do this, watch

Hi, sorry for the late reply, but this is problem occurs, because the paper size is fix. It is set hardcoded to A4. I will implement to choose the paper size you use in your countries.

In the next few days I will also publish a concept, for the next generation of this software. It will be turned into donation-ware. You can donate what you want - even nothing - it will

not influence the functionality of the software. I will also need your and the suggestions of other users regarding the concept.
