You run the install and part way through the install you receive a dialog "Allied products not found" error. You click Ok and it seems to continue going.
We were trying to install AutoCAD 2014 from the Building Design Suite Premium 2014 media when we received that error. Since there were other problems installing, he couldn't install the whole suite at once and was installing programs one at a time, that's when this error showed up.
To get around this problem on a clients machine we needed to run the Microsoft Fix It utility and uninstall AutoCAD 2014, which is what we were trying to Install. But it didn't show up in Control Panel>Programs and Features in Win 7. It didn't show up in Start>All Programs>Autodesk and it didn't show up in the Autodesk Uninstall Tool.
MS FixIt to the Rescue!
We ran the Microsoft Fix it utility and ...
Select that you have an install problem...
Scroll down and click "Run Now"
Click to "Detect Problem and let me select the fixes to apply"
Click "Uninstalling". I like this one as it shows you everything the FixIt utility things may have been installed, even when you cannot see it anywhere (no shortcut icon, nothing in Programs and Features, etc...)
Now we wait a few....
Here's where it gets interesting... The clients' machine had AutoCAD 2014 and the AutoCAD 2014 language pack listed, but it wasn't listed anywhere else you'd normally see it. So, we selected the language pack and clicked next.
It uninstalled the AutoCAD 2014 language pack and we ran the Fix it utility again to remove AutoCAD 2014. After both were uninstalled, we started the install and it went through just fine!
Thank you Microsoft for the Fixit Utility!
