Windows VISTA upgrade to Windows 7 problem - failure
Hello.
This topic has been discussed to death but still..
I have some major problems with upgrading Windows Vista, that I could not find any discussion about.
Here is the deal - I have a customer, that had Windows Vista (Slovenian, Home Premium) and bought Windows 7 for upgrade (also Slovenian, Ultimate). Naturally we ran the upgrade adviser and it checked out just fine - it did complain about some Power DVD program but I ignored that since I have upgraded before by others without problem. So the upgrade process began, it ran almost to the end when it suddenly, just before the end, resulted in error that said something about "unspecified or unknown error" and the installation should be ran again (and can not be continued). We tried to reboot without any luck - installation just keeps resuming - ending with the same error, also, it is impossible to run the upgrade again - because another one is in progress, I guess.
So I ask - how to finish the upgrade or, if able, to revert back to Vista - my customer NEEDS working system - he has many programs that are vital for his business and/or business continual. I know that he should back up his important files and such, but there are some accounting databases that could not be backed up so easily by him - and we are past that point now.
So please, any advice or suggestion on the proceedings would be welcomed and appreciated. Thank you!
