Cannot install AutoCAD MEP 2015

[grd.aph]

I have downloaded AutoCAD MEP 2015 as free trial. But cannot install because it aborts messaging that another more recent version is already installed. I've never installed MEP any version. But I've another Autodesk products 2015. I think maybe their updates are more recent than download version of MEP 2015. Any help? thanks.

Check if the program is listed in Applicattion Manager.

Start > Autodesk > Autodesk Application Manager > Autodesk uninstall tool

If the MEP 2015 is not listed here it may be related to corrupted registry entries, or possibly some beta versions.

You may also want to take a look at 'Fix it' tool available from Microsoft:

I would try uninstalling the Autodesk Applications Manager and then try reinstalling AutoCAD MEP.  If you really want the applications manager then MEP will reinstall it by default and then it will upgrade to the latest version.
