Your 64bit AutoCAD 2015 was never designed to run in Windows 10 (this version of Windows is newer than AutoCAD 2015). In order for your AutoCAD 2015 to run as it did in previous versions of Windows, you need to follow these easy steps…
NOTE: These steps do not bypass normal Autodesk licensing/authorization, you should expect to use your own serial numbers in the normal way.
If you use VBA inside of 32bit AutoCAD you will have noticed that it is around 1000x times slower when running the same VBA code inside of 64bit AutoCAD.
This is because AutoCAD 64bit ships with the 32bit VBA DLL in a separate out-of-process executable rather than loading the VBA DLL inside of AutoCAD itself. Therefore, a lot of marshaling is incurred communicating between the out-of-process VBA executable and 64bit AutoCAD.

The best solution is to install 32bit AutoCAD on 64bit Windows, here are the affected versions along with their solution text…
Users complain of “autocad crashes when clicking anything” and “autocad crashing when using ribbon”
It seems that a new Computers with the latest version of Windows 10 or computers that recently ran Windows Update for Windows 10 has caused Ribbon crashing issues with AutoCAD versions…
AutoCAD starts up, but any interactions with AutoCAD’s Ribbon, Status bar, or Right clicking the Command line causes AutoCAD to crash out instantly with:
Error: Unhandled Exception
We found that this issue is caused by the new .NET 4.7 update.
This update came down as part of KB3186568 and comes as standard in Windows 10 Creators Update (version 1703). Uninstalling all of the affected Windows Updates is not a solution because they are eventually forced down by Microsoft; besides Windows updates usually have security updates which stop hackers from gaining access to your computer so they should always be installed.
We have just released an update to fully fix this issue so you can once again rely on Windows Updates. We have solved this problem via our Longbow Converter App, you will need V10.18 or newer. Here’s what you need to do:

Using Windows Explorer, copy Disk 1 of your AutoCAD LT 2015 CD to your hard drive, to a folder path c:\Autodesk\AutoCADLT2015
If you have more CD’s, copy them all directly over the top of Disk 1, overwrite all files in your previously copied c:\Autodesk\AutoCADLT2015 folder
If you have a single self extracting exe downloaded from Autodesk called something like AutoCAD_LT_2015_English_Win_32bit.exe
Simply run the exe, it will ask to unzip to a folder inside of c:\Autodesk, make a note of the folder for later use (we’ll refer to it from here as c:\Autodesk\AutoCADLT2015), now click OK. Wait until all of the files have extracted, when they do, the AutoCAD LT 2015 setup will automatically launch – simply close it and move to the next step.
Now, start the Longbow Converter tool, select the 1st tab named ‘AutoCAD 32bit Installer Converter‘
pick the c:\Autodesk\AutoCADLT2015 folder
click the ‘Convert‘ button.
Once the conversion process is complete
Click ‘Install/Run Setup‘ to start setup

– If you are unable to activate your product, or the activation process crashes:
The Intel Integrated Graphics is a so called “feature” that bypasses your main graphics card to utilize the integrated graphics card save power – the problem is that it for AutoCAD it literally kills AutoCAD performance.
All you need to do is disable the Integrated Graphics feature in your computer’s BIOS setup (usually accessed by pressing a series of shortcut keys right at the start of your computer’s boot sequence startup) and you will be back to normal in no time – just know that disabling this power saving feature will use more battery power obviously.
I can’t comment on how to specifically disable it in your BIOS because it is computer specific, you will have to search for that yourself – I created this link to save you the time searching for “How to disable intel integrated graphics”
