Update Error

when i open smartftp it tries to do an update and i get this error message:

and then...

Image

and finally:

'Fatal error during installation'

I updated the latest version and it was fine for a few days until now!

In the first picture I browsed and sent it to this file:

C:Program FilesSmartFTP Setup FilesSmartFTP.msi

but still nothing!
help??

but if i get the full setup will it replace smartftp entirely and will all my previous ftp accounts to different sites be gone?

yey done it thanks a lot

oh yeh 1 other question is smartftp coded in visual basic or c# or c++ ??
