I have a . tq6 certificate and have recently loaded Ububntu dumping windows on same pc. I opened TQSL and it asked for certificate. Tried loading it and got the error that it was not for this computer. Reading the instruction, it states, "If you receive a .tq8 certificate, it is absolutely essential to convert it to more usual .p12 format which can be transferred. Do this immediately!" How is this accomplished?
