I use InfoSmart 1.1 SP2 R2. I used it on Windows 7 x64 for a year or so. After I upgraded to Windows 8 x64, I could not get InfoSmart to install properly. I tried making an exception in Data Protection Execution, along with many other adjustments, but no go. P&K have a new version for Windows 8, but as I don't have a purchased account, I couldn't download it. Eventually I just loaded it into a Win7 virtual machine (Oracle) and run it from there when I need to.
More recently, SleepyHead's latest version (http:\\sourceforge.net/projects/sleepyhead/files/Testing/ - I'm not allowed to post links in this forum, so please change the first '\\' to '//' to get the correct url), I found works well with my P&K Icon. I'm using the 'test' version - 0.9.5
Hope that helps, Roger
