Anyone getting errors when they try to install?  I've downloaded the program repeatedly and get the same error everytime.

The procedure entry point

library LiteHtml.dll

I would start by searching your system for copies of the LiteHtml.dll, it maybe there are copies in folders other than the Revit folders that are causing problems. If you find this DLL in folders other than the Revit folders try renaming it then installing Revit again.

When searching your system for copies of this DLL make sure to search System and Hidden folders.

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.
