hi, thanks for the reply.
1. Actually, both softwares can be installed together. The problem was that TODO Backup 1.0 keep warning me about COMODO Disk Encryption is installed on my system and there will be problem with TODO Backup 1.0 to operate correctly. For further info, you may try to install COMODO Disk Encryption and start TODO Backup 1.0. Then you will see the warning popup by TODO Backup 1.0.
2. Nope. Never used that COMODO Disk Encryption that has been installed to enrypt any of my drive of partition. I uninstalled COMODO Disk Encryption when TODO Backup 1.0 gave me the warning.
3. Ok, thanks for this info about Win7 compatibility. Maybe the problem that I encountered will be solved in this release.
Thanks again for your help.
