Related to this question, I have Ubuntu 20.04.1 LTS. I downloaded PlayOnLinux 4.1.9 (the Precise version) and used it to install Microsoft Office 2010 Pro. PlayOnLinux downloaded Wine 1.5.21 and whatever else it needed to install office. I did a customized installation and it seems to work fine. The only issue is now that I can't quite get file associations to work correctly. So for example, if I have a .docx document, I want to be able to just double click it and have it open with Microsoft Word. When I try to do that I get an error saying "IOPL not enabled" and the document never opens. I googled it and everyone said to open up wine configuration, go to libraries, add gdiplus and edit it to "Native (Windows)" but this still hasn't fixed the problem. I have no idea what this is or how it is supposed to work but can someone who does, please help. Currently I have to start Word and then use it to open up the document. That works fine.
I am not very familiar with linux so hope this isn't too complicated and can be broken down into easy steps which I can follow and execute.
