@pulkitn, unfortunately I have to report that this solution does not work, at least not on Windows 7/64 pro. The exe file you've linked seems to be for a different OS version. Anyway, installation of FM2019 in Win 7/64 also fails using the previously described solution. I have copied the AASIapp.exe to the corresponding P7 folder (which did not contain an older version yet, though). On this computer there's a running version of FM2015 already installed, also Internet Explorer 11 with TLS 1.2 enabled. When starting the FrameMaker 2019 installer, all I get is the same old message regarding the required browser/OS update. However, there is nothing more to be updated. I've also done the recommended registry edits (solution 2) for both the AASIapp.exe and Set-up.exe. Restarted the computer, still doesn't work. Anything else to check? I really need to be able install our existing FM2019 licenses… several of them. Update: by removing the network connection from the computer I've been able to install FM2019 as a demo. Afterwards I had to replace the AASIapp.exe in the P7 folder again, because it was overwritten by an older version. However, even after reconnecting to the internet and restarting the computer, I'm still not able to enter my license information now. FrameMaker still pretends to have no internet connection, although the help menu shows the option to log off with my user name (which is probably there because of the working FM 2015 version). The message says there is no internet connection or the time on the computer is wrong (which it isn't): Update #2: I've misunderstood the instructions above. I understood "…just have to replace give Setup.exe…" that I'll have to rename the ZIP file to Setup.exe. This is wrong. After simply unzipping it, I found the file "Set-up.exe", which I then copied into the FrameMaker setup folder, replacing the existing file. Using this file the initial installation went through, however, I still get the error message shown above when trying to log in for entering the license information. Bernd
