Updating with a solution to my installation problem. Here is a recap: -Freshly wiped PC with Windows 10 (this could also be a problem for a freshly wiped Windows 11) -Fresh download from RSI website -Launcher installs -gamepack installs (~13gb) -Launcher quits transitioning to full download -Error 5007 or 5003 -Tried everything listed on the RSI website and help from volunteers (seriously great volunteers here on Spectrum) -Not even an acknowledgment from CIG on a support ticket for 8 days (screw you guys) After a week of trying everything, I had moved on to installing other apps on my computer, when I realized I had been using MS Edge as the browser, and I never use that browser. I added Google Chrome and set it as the default browser. I did a complete redownload and install using Chrome, and it worked perfectly. There were some certificates that the Edge browser was not communicating with or did not have, which were causing the problems. For CIG to let 8 days go without even a message to a support ticket is pathetic and inexcusable, but shame on me for expecting more. As much as I love this game, I do not respect the company building it. Hopefully, this unorthodox fix will help someone. I have seen others having trouble with fresh OS installs.
