To be able to install a new driver, it is sometimes necessary to first uninstall older versions. Please also note that other software packages than cadett ELSA might have installed Sentinel drivers that might interfere.

 

The standard procedure to uninstall Sentinel drivers is to use the Control Panel in an ordinary fashion. We recommend that method to be tested first.

 

However, using the Control Panel is not always successful in this respect. Therefore, there are also special driver removal utilities available, which will search the computer for any interfering old drivers and remove them.

 

Please check the directory specified below:

 

\ELSA\HWLOCK\Tools to find and fix problems\Cleanup

 

It contains two sub-folders, one for 32 and one for 64 bit operating systems.

 

In each one, you will find both a PDF instruction file and the utility itself.
