Hi Marianne,
I can only advise on the following from my frustrating experience.
Firstly, remove and dump the Device Access Manager, it will inevitably give you errors later. Its been nothing but a problem in my organization.
For everything else, I eventually re-installed notebook (Not particularly necessary) to Windows 8.
I then downloaded all the updated software needed and methodically installed one at a time ensuring to test the launch of each application before the next was installed. Allowing HP to upgrade these apps through the Support Manager broke it all.
On my eventual final replacement notebook, after temp use of another, I did exactly the same after replacement of win7 for win8. Installed one at a time as below.
Most of the app versions were 8.3, I started with Client Security Manager, then followed through with the smaller apps for File Santizer, Finger Print Validity sensor, Drive Encryption. I tried the Device access manager once and it failed again, removed that once again. Finished with HP Support Manager. I installed standard drivers also prior and during where needed.
