Hi,
Downloaded pc 0.1.9, installed it and then exec'd it.
Looked around the menus and then clicked UPDATE. It 'updated' to v0.1.7 ;-)
My system is Win7 64bit on a laptop. Cannot verify that it does this on anyone else's comp.
Perhaps check the version available on server and compare with version making query? (sorry.. not sure how you're updating). I'll stop now :-D
