Hi All, I have a MacBook Pro M1 running Mac OS 14.2. I'm running Parallels Version 19.2.0 (54827) I have been trying to upgrade to the latest version of Windows 11 Preview for some time without success. I keep getting the following error: Windows 11 Insider Preview 10.0.26016.1012 (rs_prerelease) Install error - 0xc1900101 Can anyone offer any suggestions on how to install this latest Windows 11 update? Thanks.
There is another thread on here with the same issue: Windows Update Install error - 0xc1900101 | Parallels Forums There is a link in there to a MS Feedback Hub thread as well. No resolution yet.
Hello, Thanks for bringing it up! We're aware of the issue and have already reported it to our colleagues from Microsoft.
@Mikhail Ushakov , thanks for the reply. Any update on this issue? I just updated to the latest Parallels version and tried the Windows 11 Insider Preview 26002.1000 update again but it still fails with error code 0xc1900101. Any thoughts/suggestions/guidance for successfully installing this update?
hello @DonovanD , The issue isn't related to any technical faults inside Parallels Desktop, so we've escalated it to our colleagues from the Microsoft team. As far as I know, there is no workaround for this right now but they're actively working to have it addressed (Note: Microsoft Canary channel builds could include major issues that could result in not being able to use your Windows correctly or even in some rare cases require you to reinstall Windows). I'd advise you to reach out to Microsoft support for assistance.
Windows insider builds for Beta and Developer install in Parallels with no problem. The only ongoing problem is with Canary builds which has been happening sincce Canary buil 25997. (20620 is the present Canary build). There is a VERY LONG string of reports on this that you might want to check.
