I have, for a long while, used 3DHome 3.0 Deluxe on my Windows 7 laptop. I had to download d3drm.dll to do so. I recently had to reload Windows and have not been able to install the program again because I have been unable to load the above dll. If anyone can assist me in this issue, suggestions would be greatly appreciated. I haven't upgraded because I like the simplicity of 3.0 deluxe for DIY projects.
