I'm having trouble shutting down TLS 1.0 on my Windows 7 SP1 client machines and still being able to process credit cards.
Specs:
Windows 7 Pro Sp1
SQL Server 2008 R2 SP3 with TLS 1.2 hotfix
RMS 2.0.2000
Retail Realm Cayan Processing Manager plug in Ver 1.0.0.8
Cayan Genius Terminal
RMS works fine with TLS 1.0 disabled in registry Protocol keys, until I run a credit card transaction and then I get the following error:
As soon as I enable TLS 1.0 in the registry, it works fine.
How can I fix this so that I can turn off TLS 1.0 to be PCI compliant on July 1 2018?
