renault Posted January 7, 2022 Share Posted January 7, 2022 (edited) If you have never experienced this issue, fantastic, read no further. If you have and have found a solution that works all the time for you, then ditto the same. If you have tried every suggestion, fix and concoction under the sun to no avail you might find the following of interest. Until 3 updates ago I was in the last quandary. Endless correspondence with the Zendesk, until I was just resigned to expecting that every MS2020 update will involve redownloading up to approximately 60 GB of data , regardless of the actual size of the update. Trust me, I had tried everything at that point and nothing helped. Oddly enough it was due to a problem (the same problem as with MS2020) with an income tax program install that lead to a root cause analysis and solution. The problem: Spoiler alert- I have the Steam version of MS2020, which is how I was able to watch the process in detail. The install proceeds quite normally until one of the "large" files in MS2020 needs to be updated. This often happens when you are about 97% complete it seems which only adds to the frustration when it fails. The update , in this case what MS/Asobo calls a patch file(s) downloads but as soon as it has finished decompressing the file(s), the downloader jumps back to the beginning of the download and keeps repeating the process. On many different forums I found the suggestion to delete the offending patch file, but then invariably the MS installer would try to reinstall the original large file which was GB in size. There are "thoughts" on many forums as to why the MS installer can't work properly. What I discovered was that this behavior has absolutely nothing to do with MS2020 but is a manifestation of a program that many have on their machine which is actually behaving in the way it was designed to work. I have verified this behavior both with Malwarebytes support (in my particular case) and the Zendesk. In fact, buried in the Zendesk help is a list of programs that they suggest may cause issues with an update , although they don't explain the specific issue(s) in detail. Scroll down to "Check your Antivirus or Anti-Malware/Anti Ransomware" for a list of known applications All versions - Packages installation & decompressing issues - Basic troubleshooting – Microsoft Flight Simulator Support (zendesk.com) In my case Malwarebytes has both Exploit Protection and Ransomware Protection to protect your machine from possible "bad actors". The way the algorithms work (a simplistic explanation) is that when they see a downloaded file trying to attach itself to an existing file, they immediately activate and delete the downloaded file. What I have just described is in "MS2020 speak", the downloaded patch file(s) trying to attach itself to the large base file exactly as Asobo intended it to work. However, as soon as Malwarebytes sees this happening, it deletes the patch file, the MS2020 downloader then says "no file" and starts the download again and the process just keeps repeating itself. The solution is very simple. During a MS2020 update, in my particular case, temporarily turn Malwarebytes completely off until the update is finished. Then turn MWB back on again. As I said , in my case this was both the cause of the looping issue and the solution. I have downloaded 3 complete updates (6,7 and the most recent one of Jan 6th) averaging about 100MB/sec without any issues whatsoever once I discovered what was happening in my particular case. In fact with update 6, just to check, I turned MWB back on during the process and it began looping on files it was working with in the pc-fs-base-bigfiles folder. As soon as the patch file was decompressed, I was watching the process in the folder) the patch deleted and the download restarted. I then deactivated MWB and it properly finished the update with the patch files i.e. the patch files all decompressed in sequence and then were added to the main big file and it was on to the next stage of the download. This may not be relevant to your particular installation, but if you are plagued by this problem, have checked every other suggestion and are using an independent Malware program then I sincerely hope that this info may be of help to you as it can be extremely frustrating.
