[Anonymous]

Hello (sorry for my english)

I've a problem : I had an error when installing the first time Autocadmap 3D 2015 on Win 8.1 (64bit) - it stops ...

Then I tried to reinstall and it does'nt work : it says "Autocadmap already installed"

I have uninstalled all products autodesk (following : http://knowledge.autodesk.com/customer-service/installation-activation-licensing/get-ready/remove-pr... also clean uninstall Autocad 2015

Then I reinstall Autocad 2015 : it works, but then I tried to reinstall Autocadmap 3D 2015 again and it still says me "Autocadmap already installed"... (same message...) ... I searched on internet but i didnt found solutions.

What should I do to fix it ?

Thank you;

Hello and welcome to the community @Anonymous!

One of the best workarounds when a program cannot be installed because the installer indicates that it is already installed (but isn't), is to run Microsoft Fixit.

The typical cause for such an error is caused by a prior install that has failed, left residual keys in the registry that make the installer think the program is already installed.

Failed Install - Program lists as already installed
