Microsoft’s Windows 7 Engineering Team has important information for Windows 7 Beta Users Upgrading to the (upcoming) Release Canditate.
- Upgrading from Windows Vista –> Windows 7 RC — No problem!
- Upgrading from Windows 7 Beta to Windows 7 RC — Mulitple Answers. . .Answer #1 – No. Clean Intsalls or Vista Upgrades Only: "We want to encourage you to revert to a Vista image and upgrade or to do a clean install, rather than upgrade the existing Beta. We know that means reinstalling, recustomizing, reconfiguring, and so on. That is a real pain. The reality is that upgrading from one pre-release build to another is not a scenario we want to focus on because it is not something real-world customers will experience."Answer #2 – Yes; but don’t do it: "We are going to provide a mechanism for you to use if you absolutely require this upgrade."Here’s what you can do to bypass the check for pre-release upgrade IF YOU REALLY REALLY NEED TO:
- Download the ISO as you did previously and burn the ISO to a DVD.
- Copy the whole image to a storage location you wish to run the upgrade from (a bootable flash drive or a directory on any partition on the machine running the pre-release build).
- Browse to the sources directory.
- Open the file cversion.ini in a text editor like Notepad.
- Modify the MinClient build number to a value lower than the down-level build. For example, change 7100 to 7000.
- Save the file in place with the same name.
- Run setup like you would normally from this modified copy of the image and the version check will be bypassed.
