Strange, it should be on your computer if you already have Autodesk products installed. Typically this file is in the setup folder. Perhaps your 2012 files are corrupt. Based on the fact that you already have 2011 products, I doubt it is an SSE2 issue.
Yes, those files are in the setup folder, but the install does NOT know to look there.
I got it to install by copying all the files from the DVD to the hard drive, and copying many of the dlls from the setup and 'english' folders to the outer layer where the install exe was located.
But, WHY is this happening?
Ours is not to reason why...
It seems quite common that copying the media to the HDD has always been a good way to resolve strange installation errors. Thanks for posting your work-around as it may be helpful to someone down the road.
Hey, we're all in this together, right?
But - are replies in this forum from Autodesk - or from kind souls who are helping out?
I guess I'd expected a response more along the lines of "we'll have to fix that!" from Autodesk?
This is mostly a user forum of peers helping peers. Autodesk does review the boards though and pitch in when they can or need to. Their involvement has gotten a lot better as of late.
I just experienced the same problem with AutoCAD 2013 but fortunately I know exactly what I did to cause it.
There is an idiot feature that can be implemented by system administrators that causes the DLL Load Path to ignore "dlls in the current directory".
If you enable this, you get the complaint about LiteHtml.dll.
If you disable it, you don't.
This is a .REG file to clear out the problem, but your system admin will probably hate you loading it.
Windows Registry Editor Version 5.00
If you want to experience the problem, change the value to dword:FFFFFFFF
Anyone from Autodesk who is listening needs to research the SetDllDirectory() function on MSDN and call it appropriately from inside their installer.
Try checking C:\Windows\SysWOW64 for the litehtml.dll - if there is a copy there, move or rename it & try the install again. I ran into this issue when installing AutoCAD 2013. After moving the litehtml file, I got an error with another dll. It was in the same SysWOW64 folder and had the same date as the litehtml. I ended up moving all files that matched that date out of the SysWOW64 folder. After doing that, I was able to successful install the product.
I am getting system error:Litehtml.ddl missing from your machine for AUTOCAD2013 when i try to install the trial version silently.could you please tell me a workaround for this.I have this file along with my package.
