I am about to upgrade from CS5 to CS6. I found that CS5 automatically installed in 32 and 64 bit in my Windows 7 64 bit PC. I use 32 bit to scan as it has a TWAIN plug in, and 64 bit to manipulate images as the File Automate Batch causes the 32 bit programme to crash with the plug in - but I really want to go on with TWAIN . There is a plug in for the CS6, (for the 32bit version) so I just wanted to know that it does instal in both versions as did its predecessor.
Mine did. Adobe Photoshop Lightroom = no, Adobe Photoshop CS6 = yes. However, if it does not as in the case of LR, you should be able to download either version from Adobe.
