There have been some reports that the error message "Your current operating system update level is not compatible with the currently installed version of XP/VS server!" appears.
Please check if you have install all latest Windows updates and did you update the XPVS Server version as well ?
You will find the latest XPVS Server version shown on our website https://www.thinstuff.com/products/xpvs-server/
and in the changelog: https://www.thinstuff.com/releases/changelog.txt
Might happen that system files are corrupted:
Open a command promt as Administrator and run "sfc /SCANNOW" to repair system files.
If the problem still persists, create and upload our diagnostic file TSRP (Thinstuff Support Request Package) .
Most of the time this is the fastest and most simple way to analyze 90% of possible server-side configuration problems and errors.
Please run :
C:\Program Files\Thinstuff\XPVS Server\TSSupportPackage.exe
on that computer where XP/VS Termial Server is installed and follow the instructions to upload the package.
You can upload this file directly to our webserver (https://www.thinstuff.com/tsrp/xpvs/)
We will then analyse it to find the problem.
