There is another way to change your installation of TransMagic from Workgroup to Standalone – without having to uninstall and reinstall – if you are comfortable editing text files, use Notepad to open the file called TMInfo.txt which resides in C:/Program Files / TransMagic Inc / TransMagic R 10 sp1 / System. Look for a line that says:
Network=true and change it to Network=false
Then restart TransMagic and you should be able to launch (at which point you may need to request or enter your license key).
