SDK Version(s):
Photon-OnPremise-Server-SDK_v4-0-29-11263

OS:
Microsoft Windows 10 Enterprise

I've followed the instructions in the ReadMe.md file for the plugins SDK and could not debug the project. I've tried unblocking any files initially, but none appeared to be blocked. Then, I downloaded the 100cc license, unblocked it (this was blocked) and put it in the appropriate folder. Same result. I followed the troubleshooting guide for licensing and nothing appeared to be wrong.

I've also tried recursive unblocking via Powershell.

# In SDK root directory
get-childitem "./" | unblock-file

Not sure where to go from here.

hi, @davidCan

from time to time we see this odd issue when PhotonLicensing.dll can not be loaded. Still there is no reliable solution.

look here:
https://forum.photonengine.com/search?Search=failed+to+load+PhotonLicensing.dll

try to install net3.5 to your machine may be this will help

best,

Yeah I had .Net 3.5 installed already. I believe the issue was related to Enterprise security software that prevented the loading of the licensing DLL.
I ended up working around this by building out my development environment in a Windows VM.
