Ok I have worked with Bert and we have fixed the Missing Vaccine from VIPER please install the newest version from,
http://www.medwaresoftware.comInstall it right over the old one,
After it loads you will need to run the Maintenance from the help menu.
Help - Maintenace "LET IT FINISH"
Even if this is a clean install of VIPER, run the Maintenace.
Even though you will be installing this on many pc's, you only need to run the maintenance on just ONE PC. Once it's finished it not needed to be run again, unless asked to do so.
Note that most of the old issues are coming from the file Settings.ini
If you have a startup problem please delete this file.
C:\ProgramData\Medware Software Inc\V.I.P.E.R\Settings.ini
Just the file, not the whole folder.
Note:
On some PC's this folder is Hidden, Just copy and paste
C:\ProgramData\Medware Software Inc\V.I.P.E.R
into your Address Bar Above
and hit enter
Once in the folder delete the settings.ini file.
Thanks
