i have th older virsio and i uninstalled this just now i have tried to download virsion 1.5.1.4.but the following message has come up every time
NSIS error
the installer you are trying to use is corrupted or incomplete.
this could be the result of a damaged disk,or a failed download or a virus.
you may want to contact the autor of this installer to obtain a new copy.
it may be possible to skip this check using/NCRC command line swich (not recommended).
i have tried several times but this always comes up so what do i do or is there an other version i can download from somewhere else.

thank you for any help.

Have you tried deleting the downloaded file and then downloading again "from scratch"?

The same thing has been happening to me. How can I install the package without that thing popping up
