Location of drivers in Win 7 Pro 64 bit system

I couldn't find any software/drivers on Fujitsu support pages for that discontinued scanner, what I could find seemed to indicate it was designed for win9*

So I'm puzzled, perhaps provide a link to the software/drivers pages

There appear to be some Vista drivers at the Fujitsu - Global site.  Perhaps the OP will provide more information --> http://www.fujitsu.com/global/support/computing/peripheral/scanners/drivers/fi-4x20c2.html

The fj4120c2dj is listed under the discontinued section of the support site.  Recommendations from other folks on the community indicate that I should download the Vista driver listed 9.18.709 and install it.  I have followed those instructions completely but the referenced driver does not get installed.  The most recent driver is listed as 9.20.605 and is in the Windows-fjmini folder as a x64 driver for this 4120 scaner and is installed every time.  However, it will work once installed until I log out or restart the PC, then the communication error comes up again.

I am prepared to buy a later model scanner but I am not sure that will fix this problem.  I am also prepared to restore the system folder as a last resort. 

thanks for you response.

leefrost,

thanks for the suggestion.  I used the utility but could not find any driver listed from fujitsu of anything for this scanner.

I used the 32 bit and the 64 bit utility both to no avail.

IU found the driver set up info in the Coimp0ter-windows-fjmini folder.  However the Vista driver that I downloaded from the fujitsu site is not in that folder and never gets installed.

This fjmini folder may be MS versions of the fujitsu drivers and seem to be IA drivers.  I need Twain drivers for special remote scanner operations.

I am going to try some other things today, then give up until I can be on site with this PC ncxt week.  thanks for you suggestion, I like that utility.

I downloaded the Vista driver which I am told will workwith Win 7 X64.  It is ver 9.18.709.  However, so far I have been unable to get that driver installed.

I am going o try one more time today, then give up until I can be on site with this sick PC nest week.  thanks for you help.

I would have thought that driver version 9.20.605 (which you say is installed) is a more recent driver than version 9.18.709.  I wonder where the 9.20.605 driver came from and why you believe that the older one will work better.  Perhaps, as you suggest, the newer version is not a Twain driver, although the numbering scheme suggests that it is the same as the other one.

The following is based on XP.  It's probably the same for Windows 7, but I don't know for sure. 

Typically, drivers are installed from a *.inf "package."  Inf files are text-based files containing information required by the system to install a device's software components.  However, the first time an inf file is used, Windows "precompiles" it and creates a corresponding *.pnf file to facilitate efficient processing. A PNF file includes information about the content of the original INF file, as well as the name of the INF file and other file attributes. Setup uses the PNF file instead of the original INF file. If a PNF file does not exist, Setup generates one for the INF file. For vendor-supplied INF files, the information contained in a PNF file also includes the location of the original INF file.

See http://msdn.microsoft.com/en-us/library/aa741213%28v=VS.85%29.aspx and http://www.filesuffix.com/en/extension/pnf

The reason that the paragraph above may be relevant is that frequently an updated driver has the same name for the inf file as the previous driver.  Thus, when the new inf file is saved in C:\Windows\inf, it overwrites the old file -- which is what you want.  However, when Windows goes to actually install the driver, it uses the old pnf file, which may result in the old driver being installed, notwithstanding the new inf file.

Because the Fujitsu download is an exe file (and it's not a compressed file that 7zip can open), I can't tell exactly how the Fujitsu driver installation proceeds.  However, one thing you might try is to look in C:\Windows\inf for any inf files that relate to Fujitsu.  I assume that the file names will start with fj.  If there are corresponding pnf files, either rename them (e.g., *.pnX) or move them to a non-system folder.  Then try reinstalling the downloaded driver and perhaps you'll get the new version.

I looked at the files you suggested.  there were some old fj inf files but no pnf files for any of the fj inf files.

Since I am trying to solve this problem in a remote session, I may not be completing some of these installation procedures.  I am going to terminate this effort no until I can get on site and work directly on that PC.

there has been some discussion in another community about how to install this fj4120 scanner and make it work with win 7.  this unit has worked well on this PC for a year now but just quit working a week ago.  the driver I mentioned 9.20.605 is the latest x64 driver and an installation (via driver update process) will work with Scanall and my remote scan server as long as I do not log off or change a user.  Once that happens, the twain driver disappears and no longer works.

I appreciate you help but I think I will delay any more work on this until I get on site next week
