For those of you who tried to install VS 2005 and were met with the dreaded htmllite.dll file missing message. You should know that it is not the media fault or your fault it is just an annoying bug in the installation code. The bug seems to be related to the naming of the media and location of the files.
Here is one simple solution that solved the problem for us:
1. Create a new directory on the machine you want to install VS 2005 (for example: D:\VS2005).
2. Copy the contents of [DVD Drive]\English\VS2005Pro\Disk2 into D:\VS2005(this is not a mistake copy files in disk 2 first!!!).
3. Copy the contents of [DVD Drive]\English\VS2005Pro\DISK1 into D:\VS2005(when prompted, answer yes to all, to overwrite all duplicate files).
4. Go to D:\VS2005 and run Setup.exe.
You should be good to go. Just remember to install VS 2005 service pack 1 and check for Microsoft updates after your done.
