Hello mike, thank you for your response. i appreciate your concern. yes, the scanner gets listed under "devices and printers".i would suggest you to add the scanner under "devices and printers" and then set it as default.to add the scanner, please use steps provided in this article.. Change which programs windows 7 uses by default. content provided by microsoft. applies to: windows 7. select product version. a default program is the program that windows uses when you open a particular type of file, such as a music file, an image, or a webpage. for example, if you have more than one web browser installed on your computer, you can choose one of them to be the default browser. To specify which programs are set up in windows 7 and windows vista, follow these steps: open the control panel. choose programs, and then beneath the heading default programs, click the link set your default programs..
Wia 2.0 work perfectly, i can scan and set properties of scanner, but i cant use button on front panel of scanner for scanning. i had older hp scanner and when i pushed scanner button, on winxp was showed box with programs (these programs can be changed by windows registry) or my program handle event (actually i think that there was wia 1.0 maybe).. With windows 7, you have more opportunities than ever before to override the default microsoft programs with your own choices. make sure that the program you want to make default is fully installed. otherwise, windows can’t find them and doesn’t offer them.. 1) bring "epson v500 photo scanner start button program" to front. (in case it's buried beneath a bunch of windows and to make sure it's the window in focus) (in case it's buried beneath a bunch of windows and to make sure it's the window in focus).
