First installation Anaconda3.7 (64 - bit Windows) is very successful, can also be used, but I never put off till tomorrow what you can put to use Anaconda2.7, so I uninstalled Anaconda3.7, on the official website to download Anaconda2.7 (64 - bit Windows), the below error, and nowhere Anaconda,


I tried the following method 1 to 4, all useless:
Method 1: (1) use the administrator to run: conda prompt

(2) execute commands conda update anaconda - the navigator

(3) or not try command: anaconda - the navigator - reset
Method 2: change the install path, anaconda from E disc to install to D plate, after installed still appear the same mistake, can't open anaconda (with an administrator to run nor
Use),
Method 3: doubt after the first installation anaconda uninstall uninstall clean, after I install the anaconda in E disk, unload E dish associated with anaconda software file deletion very dry
Net, so I worry about is system disk (C) some related to software files, I don't know, I will use "file search" to delete the disk C under all about "anaconda"
And "conda" file, reinstall the anaconda, is still the same error,
Method 4: open under the control of the "environment variables" in the advanced system Settings, see the "ComSpec" whether the value of the variable is
"% SystemRoot % \ system32 \ CMD. The exe", I have no problem, as shown in figure:


I see a lot of bloggers, have you tried many ways to did not solve my problem, hope to know the net friend can help me see, give me a little help, now do you really worry,
