Which files do I have to install on the customer side?
You just have to install the LicProtector.DLL and the license file with your application. That is all - no active service on the server is required, even when using the concurrent user testing. The DLL has to be registered either with an installation setup or with regsvr32.exe.
An installation, which needs no admin rights and also without registering the DLL and is possible. Click here for details.
