I don't know what kind of answers I can get on this, since I know that PcAnywhere has discontinued support, and has put the product on the "sunset" list.
I was very disappointed that they are no longer enhancing the product, but am posting this anyway. I have 2 machines that are running Windows 8.1, 64-Bit and another that is running Windows 10 64-bit. I was able to successfully load PcAnywhere version 12.5.5 Build 1206 on both machines, and with a little "tweaking" of security settings, I was able to get BOTH MACHINES to work with it...with one exception.
Using Remote TCP/IP Connections from either of these machines to a Windows 7, 32-bit machine and to a Windows XP machine works perfectly. However, when the Windows 10 and Windows 8.1 machines are set up as "Hosts" and you attempt to make a Remote Connection TO THEM, regardless of machine type that you connect FROM, the host refresh rate back to the remote machine is VERY SLOW.
I have read every blog and answer I could find on the web and on Symantec's support sites, and have tried disabling the Mirror Driver, updated the pcanyquickconnect.dll file with an update they posted, and checked my router for passing UDP packets, etc. I have updated Video Drivers, Network Card Drivers, etc., all to no avail to make the host refresh back to the remote "quicker."
I'm suspecting the problem has to do with the video graphical enhancements provided on Windows 10 and Windows 8.1, but cannot be sure. The settings on the Graphic options on these 8.1 and 10 host machines are very complicated...things like "Anistropic Filtering,""Async Flip," and "Triple Buffering" are a foreign language to me, and I'm not even sure if changing any of these settings is feasible.
I will write more regarding the problem after getting some ideas from your forum, but was wondering if anyone has had ANY SUCCESS solving speed issues connecting to Windows 10 or Windows 8.1 using TCP/IP, and can give me a better direction on solving the problem. I have also tried running the awhost.exe on these machines under different compatibility modes such as Windows Vista or Windows 7, but it didn't help.
If I have to "live with" the slowness issue I will, but would greatly appreciate it if someone may have a solution to this problem, or ideas on getting it to work better on Windows 10 and 8.1.
