FYI, I just sent the following to StompSoft Support with the Subject: "My bizarre experience with your Download Update for Backup MyPC v6.0":
"I was previously running Backup MyPC v5.0. Last night I downloaded your "Download Update" for Backup MyPC v6.0 from your web page at <
http://www.stompsoft.com/downloads.html?SourceID=BPUS6>.
"However, when I attempted to install your v6.0 update, I kept getting error messages stating that this update could not find any valid version of Backup MyPC installed on my computer. So I completely uninstalled and reinstalled Backup MyPC v5.0 on my computer with no problems. However, when I again attempted to upgrade my reinstalled Backup MyPC v5.0 to Backup MyPC v6.0, I still got the same error message that Backup MyPC v6.0 could not find any valid version of Backup MyPC installed on my computer.
"Then as an afterthought, I realized that I had an obsolete installation file for Backup MyPC v4.85. So I uninstalled Backup MyPC v5.0, which I have been running for well over a year, and installed this old obsolete Backup MyPC v4.85. Then when I attempted to upgrade this obsolete Backup MyPC v4.85 to Backup MyPC v6.0, to my great surprise this update/upgrade actually worked. I find this experience incredibly bizarre.
"Have I uncovered a bug, or is this part of your systems design that no ordinary mortal like me could ever comprehend? If this is in the latter category, was this designed by the same person or group that developed this new version 6.0 of Backup MyPC, which 'cannot be used to restore backup sets created with versions of Backup MyPC prior to version 6.0'"???
"FYI, all of my previous versions of Backup MyPC have been downloaded over the Internet.
