I'm re-installing on-premises data gateway (personal mode)

Here's the error message:

Hi @nsight, 

Please try to move the folder RSA from C:\Users\<User>\AppData\Roaming\Microsoft\Crypto\RSA to say C:\RSA (just in case there should be a need to restore it) then try installing again. 

Best Regards,
