I have installed EDA tools (IC, SOC32, Calibre, Debussy...)with various license files, but
I do not know how to manage these files.
I cannot assign the variable LM_LICENSE_FILE to all of these licenses.
Can anyone tell me how to deal with it or point me to any materials for solution?
It is quite simple: put everything in the same c:\FLEXLM\license.dat and it should work.
May be that you could find some problems if there are some specific environmets set by some apps. In this case you need to redirect these environments to license.dat.
