Installer Problem - "Scanning For Virus TI"


Im having an issue, that iv seen a few people mention, although the suggested fixes dont seem to be working for me.

I have a problem where when I attempt to install OS 3.3 Beta, the installation appears to run as normal, then it comes to a screen that simply says "Scanning For Virus TI"

It never gets past this screen. I end up cancelling every time, although the VST installs, it wont work obviously. The firmware never updates on my Virus unit.

Iv tried , Turning off for 30 seconds, then pluggin power back in whilst holding EDIT+ARP ON , then re-running the installer ... Still the same thing .. Also , starting the unit whilst holding TAP+CONFIG , still the same thing .. Iv switching different USB ports with no luck either .. I have 8 USB ports on the back of my PC and only 4 are in use, for light peripherals like keyboard and mouse ..

im running out of ideas .. Can anyone help please ? Specs are below.

Core i5 750
Windows 7 - 32Bit

Having the same problem with Xp32. But it works in a Vista x64 Laptop :wacko:

I have tried to install 3.3 in the same pc with Vista x86. Same errors. Keep working fine in laptop x64.

I have tried to plug in all USB ports in my motherboard...

Also I can not downgrade the firmware because the USB Update Mode only works in my laptop with Vista x64 and I can not install any 32 bits drivers in it.

I am totally block.

Thanks in advanced and sorry for my poor english skills.

After two days of a try and error process I have found a solution and a new problem.

Using a USB Port that does not work before, I have tried a different combination of connections of my mouse, keyboard, etc.

Then, install the drivers and choosing repair.

My VC now opens, try to sync the Virus but, 2 or 3 seconds later, it lost the USB Connection ("A communication error has ocurred. The device does not respond to request messages or the transmited data is corrupt")

Vista x32, Ableton Live 7, 8 Gb RAM (4)...

Keep trying

depending on how well all the drivers work under different windows versions, you might get different results. but the basic problem remains: the virus needs a USB port to itself and eventually some of the ports on your PC are shared using a root hub. the error message you're facing essentially means that only parts of the information send to the virus or received from the virus came through.
you might want to consider buying a dedicated USB card.

Hi Marc,

I bought a PCI USB card and its solved the problem, as you mentioned. I was able to update my Virus TI using the onboard USB , but only if I completely unplugged everything else, which wasnt going to work.

Im up and working now, although the interface is quite slow , and occationaly drops out of sync , displaying a red error message ... Iv seen other people mention this on Windows 7 , so im assuming you guys are already aware and are looking into a fix.

Thanks for you help.
