You have installed XP/VS Terminal Server with Core Isolation mode enabled you may encounter following error:
“ThinRDPSrv is not a valid Win32 application.”
Or you are trying to install XPVS Server and get following error message:
"Could not start Thin RDP Server driver"
Thinstuff XP/VS Server uses kernel drivers and these must be allowed to install or start - otherwise our software does not work. Unfortunately that is the case when using XP/VS Terminal Server and Core isolation mode is enabled.
How to switch Off Core Isolation ?
Open Windows Security --> Device security --> Core isolation details --> Memory Integrity --> Off
