Sorry if this is Duplicate information, I searched and didn't find anything quite like it. So here goes...
Upon having problems with the LOTRO TIE & Pando Media accelerator I decided to fire up VMware (running windows 7 in VM) and use it to download the 15GB of installation files. After the download was finished I moved the installation files to my Desktop. Next I manually made a bottle in crossover 12.1.2 and installed ONLY LotRO into it. In addition to the game the installer installed .NET 1.1, .NET 1.1 SP 1 and .NET 2.0. These were the only things that were installed into the bottle.
After installation finished I absent mindedly double clicked on the shortcut it put on my Ubuntu Desktop. Lo and Behold it started the LOTRO native launcher/patcher/login application. The application started to download the loading screens and then started to patch the game. Patching took about 10 mins and then went to the login portion of the application. I put in my info and it logged in to the server selection area. I chose my server and the launcher handed off the login to the game binary. I was floored tht it worked. Below is a video I made of the launcher working.
