Sometime after VOS3000 Client Installation it shows ‘msvcr71.dll file missing’ error, in that case you have to download the Latest DLL file from the internet. You can Search DLL file with its name and download from any authorized website. We are also attaching .dll file in our website but sometime it shows Virus or not safe. So always better Download latest one and put this file to C:\WINDOWS\system32 directory. Just simply copy and paste that file in system32 directory.
