We have seen where there can be problems installing ADR if there was a previous version of the product on the machine. Please follow the steps below to clear the machine of all prior releases:
1) Remove all versions of ADR using Add/Remove Programs.
2) Make sure the following folders are deleted:
C:\Program Files\Autodesk\Autodesk Design Review
C:\Program Files\Common Files\Autodesk Shared\DWF Common
3) Do a search for any files or folders containing the terms "ADR" or "Design Review" and delete them off the machine.
4) Delete any old DWF viewers that may be on the machine.
5) Remove the following registry keys by going to Start > Run > REGEDIT
HKEY_CURRENT_USER > Software > Autodesk > Design Review
HKEY_CURRENT_USER > Software > Autodesk > DWF Common
HKEY_LOCAL_MACHINE > SOFTWARE > Autodesk > Design Review
HKEY_LOCAL_MACHINE > SOFTWARE > Autodesk > DWF Common
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Uninstall > Autodesk Design Review 2010
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Uninstall > {55D9E026-DCB0-46FF-B60A-68B972228CF6}
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Installer > UserData\S-1-5-18 > Products > 620E9D550BCDFF646BA0869B2722C86F
6) You can then try to install ADR once again. I am going to put a link below where you can find it on our website. On this page you will see two options for downloading the program. You want to choose the 'EXE' option. This will then download the entire program as well as all other files that it needs to run. This includes things like the proper version of .Net Framework and other necessary files. It is a large download, but I think it may be the best way for you to make sure you have all the correct files.

Are these XP or Vista machines? 32 or 64 bit?
