I have tried installing Chrome on numerous occasions thinking that this time it will work and every time I get "The installer encountered error 102." At one time I did have Chrome installed, but then I couldn't install the updated version, so I completely removed Chrome and now I can't get it installed.
I am running Windows 7 Pro 64-bit. I have tried the troubleshooting steps mentioned and didn't help me in any way. I have tried logging into the same PC under a different account with the same results. I have ran the installer as Administrator - same thing. I even changed the compatability mode to XP SP3 and I still get the same error.
Not worth it enough to rebuild my system, but I think that is the only way I will get Chrome installed on this system again.
