Hopefully someone might be able to help me, kinda pulling my hair out now (what I have left anyway!). Last night I upgraded a Windows 7 Pro install to Windows 8 Pro and activated by KMS (happy days!). The problem is now that I cant seem to upgrade to 8.1. I have managed to install with the default Pro key up to a certain stage at which point during an expected reboot it returns me to the Windows 8 desktop and says that a problem occurred and Windows 8.1 cannot be installed. Has anyone else experienced this before or know how to solve the problem? Any help is greatly appreciated.
ive had simmilar situation when i was out of space on the C drive. other then that what was the error message? Please check if there is any error in setuperr.log file and setupact.log file and post it here.
You can and I have just finished doing it. Install kept failing until I removed my 2 hotplug drives. Sailed through the install after that with the default GVLK and then activated by KMS.
What meant was you can't upgrade using the Windows Store, if you used a KMS key, you have to upgrade using a VL version of Win8.1 Pro or Enterprise iso. Though I would recommend a clean install, cause lots of users have had problems with upgrading.
Thats fine (and what I myself would normally recommend) unless you have everything working just the way you want it. Lots of different programs doing exactly what I need and want. All is well now, working fine
