I've been searching for a solution for a few days now, I've browsed through countless of threads everywhere, and no one seems to have the same problem as me. I've even searched through all Hamachi related threads on the Swedish tech forum I daily visit. So here's the deal; about 1 year ago I uninstalled Hamachi from my computer (don't ask me why) and lately I wanted to get it again. So I downloaded the hamachi.msi installer from the LogMeIn website, ran it; and got the message that an older version had been found on the computer and asked if I wanted to update it. I clicked no, which caused the installation to turn off completely, I started it again and clicked yes this time, which caused it to proceed with 5/6 of the installation before shutting down and giving me the message saying that it couldn't be installed and that no changes had been made to my system. After this, I started googling around, I found that if you deleted all logs and registry entries connected directly to hamachi it would work. But as always when it comes to me and software, it didn't. Now, when I try to install it gives me the message; "LogMeIn Hamachi Version [PREVIOUSVERSION] has been on your computer. Would you like to proceed with an update?". Just like the last time, when you click no it shuts down completely, and when you click yes you get the message saying that it couldn't be installed and that no changes has been made to the system. Here's a guy who seems to have the same problem with his Hamachi installation, but his solution doesn't work for me: http://forums.techguy.org/all-other-software/1009134-logmein-hamachi-installer-error.html System Specs Windows 7 AMD Athlon II x4 640 @ 3.3 GHz Gainward GTX560 Fractal Design Tesla 650W Gigabyte GA-870A-UD3 Rev 2.1 Western Digital 7200 RPM 64MB 1TB A little offtopic..
