Diablo 2 version 1.0 please insert play disc error Diablo II failed to run. Please make sure your Diablo II Play Disc is in your CD-ROM drive, then click on 'Retry'. Never saw a solution online for my problem, hopefully this will help other people out. Install classic Diablo II version 1.0 After the video test select DirectDraw 2D. I couldn't get it to run in 3D selection. set windows 7 theme to windows classic (right click desktop, click personalize, find windows classic theme). Right click Diablo II icon select properties, click Compatibility tab. Check Run the compatibility mode for Windows 7. then right click any where on your desktop, and click screen resolution. then double click diablo ii icon and play. If any of you guys have any solution to play in 3D please let me know how you did it.
