Trying to upgrade MSE I get the error 0x80070643. Rebooted and tried again with same result. Don't know what to do.

Just finished running the upgrade as the built-in administrator. Worked OK.

Now run a full system scan so no more errors occur.

This is the golden question of the century. It appears MSE does not play fair with other AVs when upgrading.

I am using Threatfire on the side and MSE's upgrade kept giving me errors. After trying variations with my install process, disabling TF (not uninstalling) I came to the realization that it is not playing when it says you have to uninstall your other AV.

So download the MSE installer from the website (I avoid MSE upgrades/updates through Windows update), I also downloaded a new installer for my other AV (just in case there is a newer build for that as well)

I disconnected my internet, uninstalled both AVs - made sure all was removed through the add/remove/registry/windows install cleaner and installed MSE then TF and it appears to be ok so far -

2 Things I have learned:

1) Install with a fresh installer - don't run the upgrade/windows update options
2) Make sure all other AVs are uninstalled

I can't guarantee this is a consistent process for all machines, but it has finally worked for me

Two issues: Upgrade install of W7x86 fails and W7x64 fails to clean install
Clean installing W7 x86 is no problem. But 1) upgrading Vista x86 to W7 x86 fails and automatically rolls back to Vista, and 2) attempt to clean install W7 x64 results in BSOD when rebooting to finalize the process. Any suggestion would be appreciated.
