Support for TLS 1.2 required to install BankBI Upload Agent

Due to the deprecation of Transport Layer Security (TLS) 1.0 and 1.1 in March 2020 (https://arstechnica.com/gadgets/2018/10/browser-vendors-unite-to-end-support-for-20-year-old-tls-1-0/), the BankBI Upload Agent needs to be installed on an operating system configured to use strong cryptography by default.

An up to date version of Windows 10 or Windows Server 2019 will support this natively. Older versions of the Windows operating system may cause issues with Powershell and .NET Framework applications connecting to web servers that require a minimum version of TLS 1.2.

To make this the case, ensure that the required security updates have been installed and set the SchUseStrongCrypto flag is set to 1 in the registry. You can perform this update by importing the following .reg Registry file.

```
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v2.0.50727]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001
```
