The scanner application failled to start because of missed STI.dll operating system is Vista

try reinstalling the scanner driver (right click on the installer) but run it as administrator so that all its files will be allowed by vista, check also if your scanner is compatible with vista

Vista driver for 1200S scanner

Install on Vista and Windows 7 using driver files from a XP installation. Copy the following driver files from XP: umax.inf, layout.inf, sti.inf, scsiscan.sys, sti.dll, umaxscan.dll, umaxud32.dll, umax.pnf (this may be more files than you need, but it works). Edit the umax.inf file to remove all by the 1200s/SCSI related sections (or copy it from below). Perform a manual installation of the 1200s and select the umax.inf installation file that you copied and edited. This worked perfectly. My Umax 1200s is recognized and works great in Windows 7.

Compaq S4 100 scanner won't work with new computer on MS Vista

I went to compaq's support site and got the XP drivers here:

I installed the drivers first S4-100 Color USB Scanner Drivers for Windows XP

Then installed the application: Vistascan Support Software Module for the Compaq S4-100 Scanner

*be sure all your "Windows Updates" are up to date.

Once installed I had to go to the default directory C:\VistaScan to find the .exe file. The software booted right up! But, it said the device was not on. I simply pulled the USB out and put it back in and it worked perfectly.

I imagine you might have to start up vista scan and pull the USB cord in and out every time you reboot your machine, which is kinda a cheap work around. However, it is a way to "give it to the man"!! and I like that idea ;)

Canoscan driver

Check Canon. But don't hold your breath- the peripherals industry are up in arms about have to provide drivers because of Vista. If the Scanner worked on XP/2000 it should have carried on. But no chance if it is one from the 95/98 era. I am not familiar with yet with Vista[perhaps never will be] but in XP under Start/Programs/accessories/ you would find a compatibility tab. here you can reset the system to run as 95/8- does such a thing exist with Vista?
