Unable To Install UltraVNC

Post by Derekbarfield »

Friends, good afternoon. I hope you are doing well. I'm posting this today in response to a request. When I try to install "UltraVNC 1.3.6.0" on my Windows 10 PC, I get an error notice that says "problem opening file for writing." Even when I put in my best effort to install it, the problem persists. I'm not sure why this is happening or how to fix it. Is there anyone who can assist me in resolving this issue? Any suggestions would be greatly appreciated.

My 2 guesses are 1) 32 vs. 64 bit or 2) permissions related.
