By Adobe Reader, I presume that you mean Adobe Acrobat Reader??............Adobe Reader, Adobe Flash, ............. IS that Clear enought???.............
By Adobe Flash, I presume you mean Adobe Flash CS4 (and not the Flash plugin for web sites)??
If so, then I have to say that Adobe Acrobat, Adobe Flash CS4 and even the Flash plugin are working fine on my system. To use Flash you must be using a 32-bit version of your browser, if you are using the 64-bit version of Internet Explorer, then unfortunately Adobe has not released a 64-bit version of its plugin yet and therefore will not show any flash based pages/parts of pages.
Sorry I don't use the other programs which you mention.
