Both the 3666 and 3677 builds have broken installers which lose the serial number during the "upgrade" process... It is INCREDIBLY frustrating to myself (as well as others in this forum) when you folks screw up an Installer as it takes THREE reboot cycles (one to discover the install failed, another to uninstall and a third to re-install) to get the product properly installed AND then we are forced to recreate all scheduled jobs (since you "lose" the scheduling info but keep the "job" entries). Then, after all that horsing around we then discover that you didn't even fix the bug! Don't you people even TEST your new builds? If you did, you would discover immediately that the installer didn't work. I've been a professional software developer for over 25 years; I would have been fired long ago for the sort of sloppiness we see on a fairly regular basis from Acronis. Another help would be to DOCUMENT exactly what is changing in each build; not simply say "Better hardware support and GUI fixes" which is what you list for the last 20+ builds! If you tell us the truth, we would notice that a given fix was NOT in a given build and we could skip it waiting for the next one. As a professional, I understand that bugs happen and are a part of the software industry but the goal is to REDUCE the bugs; not simply chase them from "room to room".
