This issue has been known to occur when installing and accessing Silk Performer on a remote machine through an RDP session.  RDP connection settings can affect the operation of certain Silk Performer components when enabled.  

Under Local Resources in the RDP options tab, if printers are enabled this triggers the installation of a virtual printer driver (this process happens in the background) which gets installed on the remote machine and this installation can lock access to specific parts of the registry required by Silk Performer. 

To resolve this error click on START | RUN | mstsc [enter]. Click on options and go to the local resources tab and disable printers.  At this stage try connecting and starting Silk Performer.  If you have installed Silk Performer over RDP with printer's enabled then you may need to uninstall/reinstall with the printers options disabled to fully resolve the issue.
