PDN Analysis Static IR drop sim fails

$

I'm experimenting with PDN analysis on a trivially simple design (2 DC sources, 4 caps and 1 load resistor).  

 

Static IR drop analysis fails with this log message:

10:46:04:       Parse all pin shape short ...

10:46:04:               Parsing static model for all power/ground/signal traces...

10:46:05:       Generating static model by field solver ...

10:46:13:               Fail to solve umf matrix in 64bit with error (-127).

 

Single Node analysis succeeds with no errors.

 

Power Integrity  analysis fails with this message:

<my installdir>\SPB_16.6\tools\pcb\bin\pdnsim.exe is not a valid Win32 application.

 

 I haven't found any references to error code -127. 

Has anyone seen these errors before?  I'm having no issues with Capture CIS, or other Allegro license options.
