NSIs error:error Writing temporary file. Fix sure your Temp folder is valid

Wife used his own WIN7 system for some time, has been said that the system is getting slower, let me help her reload the system. All right, then reload the order. Luckily, I backed her up with a ghost after installing WIN7. Shutdown, GHOST, wait 6 minutes ... OK, installation is complete. Then is to install the prerequisite software, what 360 Ah, QQ Ah, Sogou Input method ah. But the problem is, no matter what software I install, always reported "NSIs Error:" Error writing temporary file. Make sure your the Temp folder is valid. "" This error, see figure below.

However, if I move the software to the system disk (c disk) for installation (which is always installed in D disk), there is no problem that can be installed. MD, what's the problem? Start Google, saying that it is possible that the TEMP and TMP folders specified in the environment variables (see the figure below) may not exist, but they are really real.

Then I thought it was the right access to the folder, and after check, I found it was fine. So I really confused, I do not know what to do.

Finally, on a foreigner's website found a friend sent a similar issue of the post, there is such an order in the post, he said he tried after it: "Icacls D:/setintegritylevel H". (Note: where D represents the letter of the problem, please modify it as the problem letter) I tried to try the same attitude, OMG, really good.
