I recall reading that most apps should now install silently when the portableapps platform is running but I notice on initial download and install, the majority of apps still seem to present the MSI dialogues?
Also would it be possible to have a dropdown list of suggested selections e.g. All, Popular?
Most apps updated in the last few years will be silent unless they have a license to agree to. Which specific apps are you seeing this with? What OS are you on and is it 32 or 64 bit? What's the full install path? How large is the drive it's on? Do you see a warning before running through about drive over 2TB or installing older apps? Have you tried rebooting your PC?
Sometimes, the impossible can become possible, if you're awesome!
