Loading dlls ERROR (oFusion Hotfix No.310)

Hi
I’m Technical Director of Gemhorn Co.( http://www.gemho.com/web/) After we install the “oFusion Pro Hotfix No.310oECMSâ€

It seems you have applied the hotfix to the 1.8.x series

To install the hotfix #310oECMS you need to have the 1.9.16 version installed first
