Question

Answer 1

You must register zkemkeeper in every computer that will use your program, not just in the development environment.

To register the zkemkeeper dll in both development and deployment computers, follow the steps provided in the solution of this post: Error when inserting finger print data into database table. When registering in deployment computers, avoid the steps related with the Visual Studio.

You should also take a look to this document, it provides useful information to understand how zkemkeeper works: COM Class Objects and CLSIDs.

Best regards.
