There could be any number of reasons. First I'd check the 2008 is patched fully and that health is 100%
I'd verify system and servicing health by running;
sfc /scannow
also system update readiness tool
Then check for errors in;
%SYSTEMROOT%\Logs\CBS\CheckSUR.log

and they're still unknown to us. Other options were mentioned. I'd suggest contacting the application developer or starting a case here with product support.
