First install I had with MVMSetup75-R2.exe was fine.
Subsequently, I can no longer install API service. Installer lists API server as getting installed OK.
Moved to Vulnerability Manager (Foundstone) as a better spot for it - Moderator
On another machine I had success installing it. I saved the relevant reg key (works on 64-bit OS), and hopes somebody can make use of it. The ImagePath and DependOnService hex keys seems to be unicode strings.
Windows Registry Editor Version 5.00
"DisplayName"="Foundstone API Service"
"Description"="Provides programmatic access to Foundstone Enterprise system."
I have very similar issue. Api service will not appear after MVM reinstallation for unknown reason. I have contacted McAfee support.
We had to reinstall whole OS. API service was installed successfully then.
