I just downloaded and installed both the 32- and 64-bit versions of Take Command. The Install processes were able to successfully start each of them. I then went to the JPSoft website to buy them and paid and got registration keys. I then shut down both the 32- and 64-bit versions of Take Command with the intention to restart them and provide the proper registration key. However, neither the 32- or 64-bit versions of tcmd will start; starting them either directly from the Windows GUI, the run box in the GUI, or a cmd.exe session yields a "system busy" mouse pointer for a few seconds followed by - nothing. Both TCC's will start however, if's just the Take Command programs that will not start.
