Downloading 32-bit RegiStar
Like all image-processing programs, RegiStar manipulates a large amount of data. The 64-bit version can access a much larger amount of image data than the 32-bit version and is much less likely to exhaust your computer’s available memory. You should use 32-bit RegiStar only if your computer has a 32-bit operating system. The vast majority of computers have a 64-bit operating system. You can verify that your computer has a 64-bit operating system by going to Windows Settings > System > About or Control Panel > System.
Return to the Download page to download and install RegiStar.
