[[image:vtl_3_EOleSysError_Message.png|500px]]<br><br>


==OUR DISCOVERY PROCESS==
* The term "Class not registered" means that VTube is referring to an external function or procedure that has not been registered in Windows.<br><br>

* We know that the installation program is responsible for registering DLL and OCX files. If the registration process fails, then VTube will throw this error.<br><br>

* I logged into the customer computer using ConnectWise Control. The computer system was not using the FARO arm, so the error could not be coming from the FARO driver not being installed (which would be one possibility).<br><br>

* The latest build of VTube-LASER was being used (v3 build 516).<br><br>

* I decided that we should then start with reinstalling VTube-LASER.<br><br>

==OUR SOLUTION==
So, we ran the VTL installation again. We ensured that it was running in Adminstrator mode.


==RESULT==
VTube-LASER loads without issues now.
