After an update the exe file seems to be removed from the game folder. I found a few old threads that mentioned this. This one with a workaround: http://www.vendetta-online.com/x/msgboard/4/26870

I just wanted to report this happened to me when I first installed the game a couple months ago and then just now after the most recent update.

Very strange. Do you have any antivirus running on your PC?

I have AVG free edition 2013. I checked the Virus Vault for the VO file and did not find it there.

Congrats. Your antivirus is out of date.

Hello, this happened again to me after the most recent update 1.8.295. The workaround mentioned in the previous post worked again. I am using AVG free edition 2014 and again no record of AVG taking action against the file. This did not occur with any of the updates between my first report and the most recent.

I bet it's your antivirus. Tell it to NOT mess with vendetta files, I know you can do this in the settings somewhere in AVG.

Or, install Avast and give that a try.

Hello, This message is just to provide an update. I set the vendetta online folder to be excluded from any AVG activity (good suggestion vskye). Today I got the update to .299. I had not logged in for over a week so I believe i was on .297 prior to the update. I was able to update and play as usual, but the .exe file was removed again when I tried later in the day. The previously mentioned workaround worked again. I will continue to monitor the issue and report. Hopefully I will be able to duplicate the issue at will to help determine the cause.
