hmm, strange!

the failure in installing the redistributable has nothing to do with the plugin!

anyway, it seems you copied the plugin in the correct place and enabled the plugin in rivatuner - good!

look in the folder where you copied the vt1165.dll into. you should find a vt1165.log there. delete this logfile, close hardware monitoring and reopen hardware monitoring again. this simply starts off with a now empty logfile and logs some info into the file.

use the pm system of this forum to send me the logfile, or upload it somewhere and i will have a look at it.
