Have you also rebooted your computer after installing?

naturally, yes.

DId you have BOTH redis before? If yes have you tried repairing them and performing a reboot?

as i said, i cleanly reinstalled them. as in uninstalled, rebooted, reinstalled, rebooted again. both redists, x86 and x64.

not sure what to do, it wont run on the laptop either (which has 64bit win7 as well)

Edit: Id like to add that this is the only trainer that has this problem. every other, including the fairy fencer f trainer uploaded yesterday, injects fine.

I also have this problem. I have both Redis installed.

i got this problem too, never had a problem with any of the other trainers on this site.

No luck here either ive uninstalled, rebooted and reinstalled .net 4.5 with no love.

Shouken told me he had broken variables in Windows according to the VC++ Redis and now trainer activation works for him. I've downloaded the trainer here on CH and activation works flawless.

You can try to uninstall the redis, reboot, install and reboot again.
