KeePass application was unable to start correctly.

Hello Experts,
A KeePass was installed in my other system unit Windows Vista 64bit with an update version of net framework 3.5.1. Opening the application was unable to start correctly.
I rather temporarily disable my NOD32 that some of my application would not start when it is on normal mode. When try to launched KeePass same error surprise me.
I reboot the system and have scan the registry of KeePass then run again but still error appear.
I'm clueless what's causing this, but it's quite annoying…
Thanks
