Vensim PLE installation error

[ntuEric]

Hello,I have downloaded VensimPLEx64Setup.exe from the email link. I am trying to install it, but I am encountering and error message after entering my registration name.(Error during installation: Do not change the installation filename) I have read the related topic on the forum (http://www.ventanasystems.co.uk/forum/v ... php?t=6201), and I have found that the process is titled VensimPLEx64Setup.tmp instead of VensimPLEx64Setup.exe in the process manager. I guess that it is the main problem, and what can I do? Thanks for your assistance!
PS: I am running the installer in Windows 10 with Windows Defender(the only anti-virus software).

Make sure you download the file rather than run the temporary version that Internet Explorer often downloads, that might be the problem.
