OVT scanner does not calibrate nor allow "acquire picture"

There's nothing you can do to make that scanner work for a Mac because it was made (and its software) exclusively for Windows.

You could try:
-use the scanner and its software on a Windows computer -go to a computer shop and have the slides scanned and saved on your flash drive

have you updated the security protocalls product websight under solutions and updates

Acquiring images from a TWAIN Device PhotoImpression accepts images acquired via standard TWAIN devices. 1. Click the Get Photo button on the Main Screen, and select Camera/Scanner. A list of your TWAIN devices will appear. 2. Select your desired device from the Select Source pull-down. 3. Select the album to which you wish to link the acquired image(s). 4. Click the Acquire Options button to set your acquire parameters: a. Specify the file format for the acquired images. b. Specify the save directory for the acquired images. c. Choose whether or not to retain the original file format (for example, some cameras may save in a specific format-you can have the program convert the files to an option of your choice, or retain the original format). d. Set the file names for the incoming files. You can choose to have the program automatically name the files using the current date, or you can specify your own unique file name. 5. Click the Acquire button if you are capturing from a still camera or scanner; click the Video Camera button if you are capturing a still from a video. Follow the procedures specific to your device to import the image into PhotoImpression.
Updates for the Arcsoft application "PhotoImpression" are available from Arcsoft
If there are connection errors, that could be from:

1. USB connection error
2. Hardware issue

Try plugging the camera (via USB) to a different port on the computer, then acquire the pictures using the included software, or your own photo editing software that is capable of acquiring images from a TWAIN device.
Hope this helps!

Install the driver for your camera from the manufacturers website.
Once the camera is installed the software will probably find it.
Also check with Arcsoft and make sure your software is compatible with windows 7. It may require and additional driver.

For a scanner driver it should not matter whether you have XP Home or XP Pro. Most probably there's a simple problem with the disc.
You can ask the vendor for a replacement disc, or go to manufacturer's website and find downloadable drivers & software there. However, on the website there may not be the full software set available, as usually scanners come with some bundled extra 3rd party software that cannot be made available online by the manufacturer for everyone to download.
The essential thing is to install the drivers properly, the other bells & whistles are not needed, you can use applications either built into the system, or available free online for image scanning and manipulation.

Unfortunately there is no arcsoft photoimpression 6 or later for mac. All their mac products can be found at the following link, http://www.arcsoftsupport.com/products/mac_software.asp, and as you can see, the only photoimpression being sold for mac is photoimpression 5. Sorry mate

I have the same problem. If I try to scan my colour negative it comes up totally blue. They are not very old negatives either and have been stored in the dark since developing. I can use the Black and White option quite successfully but have given up on achieving colour.

i doestn`t understand

Windows Vista Compatibility Center states PhotoImpression versions 5 and 6.5 as Windows Vista compatible.
