That would be wonderful! Also, haveing speccy installed, it would be great, if snapshots could be opened by double-clicking. For now, the only way is to open speccy, waiting it load all your computer information and then either choose load snapshot from menu or drag&drop the .speccy file on opened GUI. It should be easier.
I have taken 30 snapshots of Win XP Pro x86 computers, having different hardware configurations with version 1.04 sth. And read them with My W7 x64. Everything works for me perfectly. I also have saved .txt snapshots and created Macros for making summaries of Speccy databases. No problems there either.
