Yes, that's right! I tried a search, but the (Google) search engine told me that I don't know what I am talking about! I downloaded an application DfuSe, and tried to install it. Wine installer told me that I needed another program and offered to download. I agreed, but this was unsuccessful. However the Install Wizard went ahead and installed. But trying to run was a failure. Today, I checked .wine, and found that the whole program WAS present, so I read what I could of the Docs and other text files and found that it was a 64 bit application. And that is the problem - my venerable home assembled machine is based on a KT7 motherboard with an 800Mc/s Athlon processor, running 32 bit architecture with MEPIS 6.5, MEPIS 8.5, and Debian Lenny 5.0.7. All I wanted to know is, is there any way of running the DfuSe on this system? Thanks and Regards Alan
