Dispatcher dies after startup - sapdb / libpcr

Question

We have a NW04 server on Windows whose primary purpose is as an XI hub. 
It was recently moved from one network to another (same machine name) and initially worked properly, but is now not starting up.
I just had to extend the data volume, as it was full, if thats of any relevance.
It seems to be having issue loading "libpcr".  I did some searches, and re-registered the library, as well as setting the SABDBLIBDIR env variable.  To no avail.
Here's the trace of dev_w3, which seems to be the first process that dies:
