After installing Foundation 3.1i Service Pack 8, I get the following message
every time the project manager tries to load a vhdl file:
Pcm :Cannot initialize Automation - Synopsis initialization failed"
For both Windows NT/98 the workaround has been to reinstall service pack 7
for all three downloads (Aldec180, FPGA Express, Service pack for xilinx) on
top of Service Pack 8. Then reinstall Service Pack 8 (making sure to install
all three downloads again by checking the boxes for each portion) on top of
Service pack 7.
