Can't find JTAG Server

This is not a good solution. Restarting the pc everytime the jtag server is unavailable.

the jtag server is gone very often. it is not as stable as it was before quartus v.61 we have couple of licence and on every computer the jtag server still dies unexpectedly.

in other words it is still not posssibel to catch a "strange bug" with signal tap as the jtag sever dies. what we need to do ist to shut down quartus and restart quartus.

my support told us to completly setup those computers from scratch. done that but nothing changes still having a dying jtag server. even with quartus V7.0 this problem exists.

great to hear that we are not alone with that, but hopefully there is fix for this available shortly.

could it be that one of those microsoft updates has changed something that kills the service ?

btw ... the jtag server is started under the service options.
