G3010 Scanner Twain and WIA problem

[jamesastrolee]

I was running the above scanner with XP 32 with no problems.  I had originally installed Vista 64 on my computer back in 2007 but found it imcompatible with most of my software and reluctantly bought the XP OS.  So I never tried the scanner at that time with Vista.  I recently reinstalled my Vista OS and immediately got problems with the scanner: i.e the daignostic utility said that windows imaging service was not running etc.  Skipping to the next stage of the test, and there were problems with the twain side too.  Uninstalled, reinstalled, tried everything.  My OS later developed a trojan after reluctantly downloading a few of those drive utility scans.  So I had to reinstall my OS, and so decided to install Windows 7 32 bit.  Everything works great except, you guest it, the HP scanner.  My HP Photosmart printer is fine.  I have downloaded all the latest drivers, software and fixes for the G3010 scanner from the HP website but end up with the same issue(s).  My computer installed the drivers and software ok and the test operates the scanner, but simply stops at the WIA and twain check stages.  I have read up somewhat on WIA but would appreciate any help.  It was suggested that I post this issue before paying for HP support.  I had almost come to the conclusion that this scanner was not supported by Vista or 7 but I read that others are in fact using the scanner with these OS.  Any help would be appreciated.  Clearly, it is not any of my hardware that is the problem as the scanner still works perfectly on my other XP machine.  However, I have the same issue on my Vista 32 laptop.  So need some help!  Thank you!

Just thought I would update everyone on the above problem.  I managed to fix the issue(s) in the end.  It was while I was looking through the services section in good old XP (Control Panel and into Administrator Tools) that I noticed the WIA (Windows Image Activation) service.  So I looked at this same section in Windows 7.  The Service was set to Automatic in XP Home and was started.  It made me realize that the service may not be started in the case of Windows 7 (I was correct and this tied in to what the HP Diagnostic Utility had told me).   This was set to automatic as required but could not start due to two dependant services: 1) Remote Procedure Call and 2) Shell Hardware Detection.  These may not be generally required within the newer windows system but are required for certain compatible devices etc.  The WIA service required me therefore to start both these other two services (there may also be processes required for your HP device which may require starting to.)  However, on doing this, the HP Diagnostic Utility advanced and completed the WIA stage of the test, allowing me to scan with the Microsoft Paint program.  However, the test failed on the HP Twain stage, even after a reboot.  So I then decided to uninstall and then reinstall the G3010 software.  I followed this to the letter and then opened the HP Solution software program, and behold for the first time, the scanner symbol was present and could be selected.  Shame I bought a new OS before taking the time to resolve the issues but got there in the end.  Hope this helps someone.  Well that's it folks.  So if you want something doing, well "do it yourself."
