Check how INSITE uses DiagnosticTestFramework.dll to call ksp_libfnp.dll to get the license data.
Patch ECC by patching FNP dll.
Take library files from FNP sdk, make signature file for IDA.
Use test scripts and scripts found in sdk to get used to how the FlexNet Publisher activates software.
Find multiple package/product types/groups. SIR, HD, LD, MR, etc.
Find default ruleset, change validation period from default 90 days to 9999 days.
Create custom tool using Visual Studio to automate process after testing, use import fnp sdk and patched fnp dll.

That’s more work then you need to do, but it still works. I used a patched libFNP embedded in my application project to inject the ASR into TS. The original library then treated it as a legal legit license. There’s always a weak point, especially when Trusted Storage is involved.
