Hi, I'm trying to install native SDK for z10 on my win7 laptop, after double click the installer exe file, the screen shows the extracting percentage window, after it hit 100%, it shows a bit "!" icon, and ask me to choose another directory to extract. I tried other directories, but it still loop here. Anyone has same issue like me? or if my win7 laptop doesn't meet the NDK requirement? but if it's the case, it should tell the user about it.
