Error Number 5 while registering dll

I am having trouble while installing a program called "M1" which is a production/manufacturing software package. This software works fine on XP but am having trouble getting it to make friends with Win7 Pro. It gives me the following error:

Error number 5 occurred while registering
c:\users\jason\m1\TOOLS\Crystal\WinNT\atl.dll

So I register the dll by going to:
Start
regsvr32 c:\users\jason\m1\TOOLS\Crystal\WinNT\atl.dll
and it gives me a registered successfully message.
It then tries to run the program and puts me in a loop, telling me that Error number 5 has occurred.

Ideas???

It then gives me a missing file error.
I have attached a copy of the error.

When i try to register the msado.dll it gives me this message. It appears that the file cannot be found but I verified that it is there.

Lemur,

I checked out the URL for the msado15.dll and just did what it said... i did a regedit and searched for all instances of the "commonprogramfiles" string and replaced it with the correct string. It let me do it in all places except 2. I tried to run the program and now it doesn't bark at me about the msado15.dll anymore but is now stuck in a loop of wanting to upgrade the client software.

I can try running it on a machine running virtual XP. I haven't tried that yet but is a great idea. No go on the compatibility mode.
